Abstract:
Abstract We describe a new species of shorebird, tentatively referred to the family Charadriidae, from the Huadian Formation (Middle Eocene) in Jilin Province, China. In general morphology the specimen closely matches that of an extant charadriid, and corresponds in size to the Killdeer (Charadrius vociferus). If correctly identified this is the oldest record of the Charadriidae. The Middle Eocene paleoenvironment of the Huadian region is thought to have resembled a subtropical swamp. Un Ave Playera de China del Eoceno Medio Resumen. Describimos una nueva especie de ave playera, tentativamente clasificada como de la Familia Charadriidae, de la Formación Huadian (Eoceno Medio) en la Provincia de Jilin, China. En términos de morfología general, el ejemplar coincide mayormente con la morfología de un charádrido actual, y se asemeja en tamaño a Charadrius vociferus. Si la identificación es correcta, este representa el registro más antiguo para la Familia Charadriidae. El paleoambiente del Eoceno Medio de la región de Huadian se asemejaba probablemente a un pantano subtropical.

Abstract:
The present work is one of several planned articles on updating information on the biodiversity of malacofauna and palaeogeography of the Middle-Late Eocen Tavda Sea, which existed in the Western Siberia. Paper contains data on fossil species diversity of the family Naticidae of the Middle and Late Eocene West Siberian Sea and on drill holes. The drill holes indicate predator activity, prey of Naticidae and influence of abiotic factors on their behavior. Previously the invertebrate macroauna of the Eocene of Western Siberia was not studied. As a result, the biodiversity, paleogeography and paleoecology remained incompletely studied. This requires additional collecting, generalization and systematization of paleontological material.

Abstract:
The article considers the results of a comprehensive study of the Cretaceous-Eocene deposits of the Central Crimea (Ak-Kaya mount.). The temperature and salinity of the formation of Maastrichtian and Eocene rocks have been determined, and a correlation has been made with the global climatic event EЕСO (Early Eocene Climate Optimum). The synchronicity of the formation of steep submeridional fractures and the basal horizon of the Eocene has been proved. Three major stages of deformation have been identified: pre-Eocene, Eocene, and post-Eocene. It is shown that the Eocene stage corresponds to the formation of paleoseismic dislocations during the main phase of tectonic activity in the Pontids (Eastern Turkey).

Abstract:
The tectonic complexity to which the post-Cretaceous Cesar-Ranchería basin has been subjected has generated alterations in the evolution of its oil system, evidence of this is the lack of stratigraphic record in the Cesar sub-basin belonging to ages ranging from the Eocene to the Early Miocene. These units that are no longer present could have been deposited and eroded during this period of time, leaving their mark on the closest overlying units. Previously mentioned hypothesis oriented this research to study how the basin filling was in the time range from the Eocene to the early Miocene based on both organic (24 Tmax and 14 %Ro data) and inorganic (514 data of porosity) paleo-geothermometer data of Paleocene age formations present in two new wells ANH-LA LOMA-2 and ANH-CR-LOS CEREZOS-1X. In addition to the data provided by the wells drilled for this study, 31 published Tmax and 13 %Ro data from Los Cuervos Formation in the Calenturitas and La Jagua Mines were used. The results obtained indicate that the continuous deposition of sedimentary units did occur from the Paleocene to the middle Eocene and it is expected that the Sedimentitas del Eoceno Formation has reached a thickness between 2.5 to 3.5km with characteristics of quartz sandstones (density and compaction). This thickness of rock began to be eroded in the late Eocene to the Miocene according to recent thermo-chronological studies. The evidence obtained allow to improve the thermal evolution models of the oil system, to establish when the greatest advances were made in the transformation ratios and to estimate how the oldest source rocks of the Cesar sub-basin are currently in the studied area.

The section extends from Maestrichtian Subzone CC25a to lowermost Eocene Subzone NP9c. The composite Paleocene-lower Eocene Dababiya section recovered in the core and accessible in outcrop in the DababiyaQuarry exhibits an unexpected contrast in thickness between the Lower Eocene succession (~Esna Shales) and the Paleocene one (~Dakhla Shales and Tarawan Chalk).

Abstract:
A map of reconstructed Eocene physiography and drainage directions is presented for the southern Interior Plateau region, British Columbia south of 53°N. Eocene landforms are inferred from the distribution and depositional paleoenvironment of Eocene rocks and from crosscutting relationships between regional-scale geomorphology and bedrock geology of known age. Eocene drainage directions are inferred from physiography, relief, and base level elevations of the sub-Eocene unconformity and the documented distribution, provenance, and paleocurrents of early Cenozoic fluvial sediments. The Eocene landscape of the southern Interior Plateau resembled its modern counterpart, with highlands, plains, and deeply incised drainages, except regional drainage was to the north. An anabranching valley system trending west and northwest from Quesnel and Shuswap Highlands, across the Cariboo Plateau to the Fraser River valley, contained north-flowing streams from Eocene to early Quaternary time. Other valleys dating back at least to Middle Eocene time include the North Thompson valley south of Clearwater, Thompson valley from Kamloops to Spences Bridge, the valley containing Nicola Lake, Bridge River valley, and Okanagan Lake valley. During the early Cenozoic, highlands existed where the Coast Mountains are today. Southward drainage along the modern Fraser, Chilcotin, and Thompson River valleys was established after the Late Miocene.

Abstract:
The development of modern glacial climates occurred during the Eocene-Oligocene transition (34 to 35.5 Ma) when a decrease of atmospheric CO2 led to a global temperature fall. The ocean was deeply affected, both in the surface and the deep-sea, suffering a strong reorganization including currents and phytoplankton distribution. Spanning that time, 35 samples from the North Atlantic Ocean Drilling Program Site 612 have been analyzed by counting coccoliths abundance in different size groups (< 4 µm, 4 to 8 µm and > 8 µm) and silica fragments abundance. Absolute coccoliths abundance were estimated with two different methods, the “drop” technique and microbeads calibration. In addition, a fragmentation index was calculated to assess the preservational state of the samples. The results obtained fit in the global picture of a decrease in phytoplankton abundance across theEocene-Oligocene boundary, although coccolith and silica fragments abundances show slight different patterns. Absolute abundances estimates showed a large difference between the “drop” and the microbeads methods. The temperature at which samples are dried seems to affect microbeads distribution, leading to an underestimation at temperatures higher than 60º C. In future work the current dataset will be updated with additional calibration and replicate counts to confirm that the “drop” estimates are the more valid results. As the fragmentation index was fairly constant in all samples, no major differences in nannofossil preservation were inferred. Coccoliths abundance drops are thought to be triggered by global temperature fall, general decrease of atmospheric CO2, changes in oceanic circulation, pulses of nutrients or a combination of those.
Under tidsspannet som täcker övergången mellan eocen och oligocen, för ungefär 35.5 till 34 miljoner år sedan, genomgick jordens klimat en stor förändring. Under eocen hade vår planet ett varmare klimat och var i ett så kallat ”greenhouse state”. Mot slutet av denna period och i början av oligocen skiftade emellertid klimatet till en kallare regim, ett så kallat ”icehouse state”. Under detta tillstånd minskade andelen koldioxid i atmosfären vilket medförde att den globala temperaturen minskade. Vidare påverkades också havet och speciellt de fytoplankton som levde där, då de påverkas av temperatur och inflödet av näringsämnen. Fytoplankton står för en betydande del av jordens pågående fotosyntes samt är basen av den organiska matkedjan. Syftet med denna undersökning är att studera förekomsten av coccoliter, små kalcitplattor som produceras av en typ av nannoplankton som kallas coccolitoforider. Coccoliter från en djuphavskärna härstammande från norra Atlanten har därför samlats in och för-ändringen av mängden fytoplankton över nämnda tidsspann mätts. Vidare har också bitar av kisel från andra växtplankton räknats. Resultatet av denna studie var att båda grupperna var rikligare under den sista delen av eocen men mängden sjönk snabbt i början av oligocen. Det finns inte tillräckligt med information för att reda ut orsakerna av detta, men det är troligt att minskningen i temperatur och CO2-tillgängligheten för fotosyntesen är viktiga faktorer.

Abstract:
Understanding warm climate states is increasingly important as projections of anthropogenic climate change indicate atmospheric carbon dioxide concentrations in the coming century not previously seen on Earth for tens of millions of years. The Eocene (~56-34 Ma) is a critical period in the long-term Cenozoic climate evolution, encompassing the transition from widespread greenhouse warmth and high atmospheric carbon dioxide levels pervasive during the early Eocene to an icehouse world with major Antarctic ice sheets and cooler temperatures. Increasingly, it has become apparent that global climate during this transition was not gradual; the middle Eocene is characterized by significant short-term climate variability with recent findings including both transient warming and cooling events. However, the timing, and nature of many of the climate fluctuations during this interval are poorly constrained. To this end, this thesis aims to better characterize the long-term background trends and investigate the nature of short-term transient perturbations during the greenhouse climate of the middle Eocene. In Chapter 2, new nine million year long benthic foraminiferal stable isotope records (~46 to 38 Ma) generated from recently drilled equatorial Pacific sediments with excellent age control are presented. These are the first records to document that the seven enigmatic equatorial Pacific Carbon Accumulation Events (CAEs) are not associated with transient global cooling and/or glaciation events, as previously hypothesized. Further, new carbonate accumulation records in Chapter 3 provide the first robust evidence for the presence of CAEs 3 and 4 in the Atlantic basin. Together, these findings constrain the feasibility of potential CAE forcing mechanisms and imply that there are only two viable mechanisms; (1) solute flux from continental weathering, and (2) increased organic carbon burial from marine assemblage changes. A new compilation (including new and published records) of carbonate accumulation records from a paleodepth transect (2-4 km) in the Atlantic and Pacific basins provides the first multi-basin look at deep-sea carbonate burial at high temporal resolution across the Middle Eocene Climatic Optimum global warming event (~40 Ma). New CCD and lysocline interpretations reveal for the first time that multiple rapid fluctuations (< 100 kyrs) and extreme lysocline shoaling (reaching > 2 km water depth) are superimposed on long-term trends. This finding implies multiple pulses of carbon input to the ocean–atmosphere system during the MECO and provides critical time constraints to potential forcing mechanisms, which have so far remained elusive. In the final Chapter 4, new lithological and geochemical data from the Atlantic and Pacific Basins are presented which reveal the global nature of the transient ‘C19r event’ (~41.5 Ma) and confirm that the event meets the criteria to be defined as a ‘hyperthermal’. Further, analyses of the stable isotope datasets suggests that the C19r event was not exceptional and is one (albeit the most extreme) of a large number of transient ‘warming’ events throughout the middle Eocene, adding to the growing body of data implying that hyperthermal occurrence is pervasive outside of the very warm late Paleocene and early Eocene.

Abstract:
A new genus and five new species of fossil cichlid fishes (Perciformes: Labroidei) are described from Mahenge, Tanzania. These cichlids represent the oldest confirmed fossils of the family, dating from the middle of the Eocene. The specimens share many lepidological characters, and, from comparison with other members of the family, are identified as being a monophyletic group. Therefore, they are described as belonging to a single genus, Mahengechromis gen. nov., named for the type locality. Detailed anatomical study of the well-preserved specimens allows five species to be identified, M. plethos, M. rotundus, M. brachycranium , M. ellipticus, and M. curvifrons spp. nov. These species are distinguished on the basis of osteological characters, including the shape of the frontal bones, hyomandibulae and opercular bones. The species are believed to be endemic to the type locality, which, along with monophyly of the species, indicates that these fishes formed a species flock. This suggests that the capacity for cichlids to form species flocks arose early in the family's history.
Previously published phylogenetic analyses of the family Cichlidae have included few characters that can be used to incorporate fossil material. Osteological features that may be useful for determining relationships are identified and used in a phylogenetic analysis of the family. The results of this analysis are compared with the results of previous analyses to determine the usefulness of the characters. This comparison indicates that most osteological characters are homoplastic among cichlids, although some of the characters may prove to be phylogenetically useful. Although phylogenetic analysis of osteologic characters does not result in a well-resolved phylogeny, the most parsimonious placement of the fossil cichlids from Mahenge is in a relatively basal position among the African lineages, as the sister group to the hemichromine cichlids from West Africa.
The biogeographic relationships of members of the Cichlidae are examined based on information from the fossil record and the interrelationships of the lineages within the family. Two suggestions have been made for the age of the family; either the cichlids originated in the Early Cretaceous or they evolved near the end of the Mesozoic. The later time of origin would have required a trans-Atlantic dispersal. Based on the distribution of Recent and fossil cichlids, the latter hypothesis is accepted. A reconstruction of the dispersal patterns and possible means of dispersal are evaluated.

Abstract:
The Cretaceous and Eocene sequence of South Westland crops out within a 6km wide coastal area from Ship Creek to the Mahitahi River. The oldest unit, the Otumotu Formation (Motuan-Arowhanan), lies with angular unconformity on the Paleozoic Greenland Group. It is divided into two members, an older Tauweritiki Member (new) overlain by the Topsy Member. Both are entirely clastic but the lower unit is significantly coarser ranging from boulder conglomerate to mudstone, while granule conglomerate, sandstone analysis of sedimentary features to pebble breccia and the upper member comprises and mudstone. Detailed suggests that the lower member represents alluvial fan and plain sedimentation in a tectonically active setting changing to a more stable semi-arid fluvial and lacustrine depositional regime in the younger deposits. The Butler Formation (new) (Piripauan), which lies unconformably on the Otumotu Formation, consists of conglomerate, sandstone and mudstone, with high and medium volatile bituminous coal seams. The sediments represent an environment of rivers and coal forming swamps and lakes which produced thick (up to 3m) coal seams. The Tauperikaka Formation (new), previously the Tauperikaka Coal Measures, (Haumurian) overlies the Butler Formation, with a disconformity marked by a low relief scour surface, and is divided into the Moeraki (lower), Paringa (middle) and Rasselas (upper) Members. The Moeraki Member consists of pebble conglomerate, cross-bedded and horizontally bedded pebbly and granular sandstone and carbonaceous massive silty mudstone. The sequence is thought to represent a coastal fluvial environment. The Paringa Member includes large scale planar tabular cross-bedding with mud drapes (“tidal bundles”), bi-directional flaser bedded, trough and planar cross-bedded sandstone, siltstone and mudstone. The depositional environment is interpreted as a tide dominated coastline. The Rasselas Member, which consists of interbedded burrowed and structureless glauconitic sandstone in which both the density and diversity of burrows and the sediment grain size decrease upwards, was probably deposited in a large open marine bay. The sediments of the Otumotu, Butler and Tauperikaka Formations are derived from a Greenland Group and Tuhua Group source which probably lay to the west of the basin. The change in depositional environment within the Tauperikaka Formation, from a marginal marine to an off shore marine environment is responsible constituents in the sediment composition, and the rock fragment component has been greatly depleted. The eruption of the Arnott Basalt towards the end of the Haumurian is possibly related to extension which led to thinning of the crust. The Eocene Law Coal Measures (new) (Kaiatan) are composed of clast supported very well rounded cobble to pebble conglomerate, well sorted medium sandstones, carbonaceous siltstone and mudstone and thick (up to 4m) high volatile bituminous coal seams. The sequence is interpreted as marginal marine, with coal forming reed swamps developing between fluvial clastic fans. A marine transgression from the east resulted in the end of coal measure sedimentation. The Tititira Formation (Miocene) lies unconformably on the Law Coal Measures. Differences in coal type and coal geochemistry distinguish the coal in the Butler Formation from coal in the Law Coal Measures. The pH of the Law Coal Measure swamps was elevated by a marine influence which has produced a distinctive coal type characterised by a low Tissue Preservation Index. The coal also contains very little inertinite compared with coal from the Butler Formation. The Coal in the Law Coal Measures can be distinguished using the relatively high Na₂O content which is totally organically associated and is present in a constant amount within different seams. The Butler Formation coal contains a high proportion of clay compared to the coal in the Law Coal Measures and has negligible Na₂O. A thrust system involving both Paleozoic basement and cretaceous and Tertiary cover rocks has developed in post, Miocene time and accounts for a substantial amount of shorting (in the range of 40km and possibly more). The Mistake fault, a splay off the Alpine Fault, is the sole thrust of the Mistake Thrust Sheet which is part of a duplex thrust system which has subsequently been buckled into an antiformal stack. The anti formal stack includes at least two other thrust sheets, one below and one above the Mistake Thrust Sheet. The thrust complex appears to extend south to Milford Sound and up to 100km north of the area mapped and it is likely similar thrust systems are developed along the entire length of the Alpine Fault.

Abstract:
The morphological and ecologicalevolution of middle-upper Eocene planktonic foraminiferal family Hantkeninidae is investigated in the context of the dramatic palaeoceanographic and climatic changes that marked the transition from Paleogene "greenhouse" to Neogene "icehouse" climatic conditions. Morphometric analysis proves that evolution in family Hantkeninidae was gradual but complex in detail with periods of relative stasis. Multiple lines of evidence demonstrate that Hantkenina evolved from planispiral clavate genus Clavigerinella and not, as was previously believed, from Pseudohastigerina micra. The ancestor of Clavigerinella was probably a low trochospiral form Paragloborotalia sp., which has been recognized for the first time in this study at a number of sites. Trends in chamber inflation, tubulospine angle and the position of the tubulospine on each chamber show the most dramatic evolutionary changes, indicating that these are the most useful characters for taxonomy. These morphological changes correlate well with known palaeoceanographic changes as well as the shift in hantkeninid ecology from a deep to a surface water habitat. Hantkeninids underwent pronounced adaptive evolution in depth habitats during the initial phase of the climatic transition. Lower middle Eocene forms lived in a cool deep-water environment within or below the oceanic thermocline and shifted to warmer surface waters in the late middle Eocene. They evolved in the low latitudes and were primarily. a tropical-subtropical group. The occurrence of Hantkenma australis at relatively high northerly and southerly latitudes during the middle Eocene may record a temporary expansion of warmer water conditions into these regions, possibly representing a hitherto unknown "hyperthermal" event. Clavigerinella is rare in middle Eocene open-ocean sequences but occasionally occurs in relative abundance in other localities (such as on continental margins and oceanic seamounts), suggesting that it was specialized for living in upwelling regions. A revised taxonomy of family Hantkeninidae is presented that reflects new understanding ofhantkeninid evolution. The reconstructed phylogeny demonstrates that the tubulospine-bearing genera Hantkenina and Cribrohantkenina represent a monophyletic clade. Multivariate analysis suggests that more than one morphological population existed at several times and that these may represent biological species. The results demonstrate that the hantkeninids are not merely passive recorders of ocean conditions but have instead evolved morphology and changed habitat in response to climate change.

Full text
Abstract:
A study of calcareous nannofossils from the Maastrichtian-Early Eocene from Egypt has resulted in the recognition of four Maastrichtian and seven Early Tertiary biostratigraphic zones. These nannoplankton zones are based upon local ranges and compared with the zones proposed by Martini (1971), Sissingh (1977), Verbeek (1977) and Romein (1979). A new zone, the Fasciculithus ragaae Zone is described and the E1lipsolithus macellus Zone and the Fasciculithus tympaniformis Zone are emended. Study of the vertical ranges of the species provided many markers (including the zonal markers) with distinctive first and/or last occurrence levels. The uppermost Maastrichtian and Lower Danian are missing in the study sections. There is no change in the lithology at the Cretaceous-Tertiary boundary as observed in the Esh Mellaha area, but biostratigraphic evidence shows that there is a time gap and the boundary missing. This boundary is, however, marked by a conglomerate band at Gebel Urn El Ghanayem, a thin bed of black non-calcareous shale at Gebel Duwi and a change in the lithology from chalky limestone (upper part of Sudr Chalk Formation) of Maastrichtian age to shale (lower part of Esna Shale Formation) of Early Palaeocene age at Wadi Tarfa. No continuous Cretaceous-Tertiary boundary sequence was analysed. The palaeoenvironment during the Maastrichtian-Early Eocene according to the nannofossil assemblages, was a warm open marine inner to outer shelf, although the absence of late Maastrichtian and early Danian age sediments limits observation and comment. One hundred and sixty five species have been identified. Descriptions, remarks and figures as well as schematic drawings of many species are presented. A new family RHOMBOASTERACEAE, a new genus Diadochiastozygus, five new species Fasciculithus ragaae, F. gelelii, Discoaster atefii, D. duwiensis and D. amrii are described. New combinations for Bomolithus megastypus, B. cantabriae, Diadochiastozygus imbriei, D. saepes, D. eosaepes, Tranolithus tarboulensis, Vekshinella dorfii and V. compacta are proposed. The evolution of some Cretaceous and Early Tertiary nannofloral groups is discussed and a link between the Bomolithus and Discoaster groups proposed.

[superscript 206]Pb/[superscript 238]U calibrated age-depth models were used to constrain the age of magnetic reversals between 26.5-36 Ma (C8r-C16n.2n). Interpolated magnetic reversal ages are consistent with relatively constant seafloor spreading rates, and provide a fully integrated and robust chronostratigraphic framework for the EOT, as shown by mutual consistency of chron boundary ages from the Umbria-Marche basin and the WRG between 31-36 Ma. These data effectively eliminate the discrepancies between astronomically tuned and radio-isotopically calibrated time scales of the EOT. An evaluation of the fidelity of planktonic foraminifer bioevent based chronostratigraphy across the EOT indicates that the last occurrence of hantkeninids and the last common occurrence of Chiloguembelina cubensis which mark the Eocene-Oligocene (34.090 ± 0.074 Ma) and Rupelian – Chattian (28.126 ± 0.175 Ma) boundaries are not timetransgressive across oceanic basins. However, other Oligocene planktonic foraminifer bioevents occur 0.4-0.8 Myr later in the western Tethys than in tropical and subtropical open ocean settings. In the WRG sedimentary succession, the first and last appearance datums of key Late Eocene mammal taxa show diachroneity of ca. 1 Myr over a distance of 400 km. Long-term aridification recorded by the WRG appears to be time-transgressive, and progressed gradually from west to east, while abrupt Early Oligocene cooling reported from WRG outcrops in NE Nebraska was synchronous with Early Oligocene glaciation of Antarctica.

Abstract:
The Early Eocene (47-56 Ma) 'greenhouse' climate represented the warmest climatic conditions witnessed in the last 90 million years, with peak Eocene warmth (the Early Eocene Climatic optimum, EECO) occurring around 50-52 Ma (Sexton et al. 2006; Bijl et al. 2009; Zachos et al. 2008; Littler et al. 2014) with subsequent global cooling thereafter (Sexton et al. 2006; Zachos et al. 2008). Ocean circulation plays a critical role in redistributing thermal energy across the planet and providing ventilation to the deepest parts of the ocean. Understanding how it may have operated in a globally warm world with little equator-to-pole gradients is paramount to understanding how it may respond to increasing temperatures today. The prevailing view of the early Eocene ocean was that deep-water formation was confined to the Southern Ocean, with little or no deep-water formation in the North Atlantic, unlike today. This study explores whether there is evidence for deep-water formation in the high latitude North Atlantic during the extreme climatic warmth of the early Eocene and its stability across transient climatic excursions. It also explores the strength and vigour of ocean circulation and whether this was influenced by the global decline in temperature following early Eocene peak-warmth. It utilises the neodymium isotopic signature of fossilised fish teeth (εNd) that is widely utilised to trace the movements of deep-water masses and can be used to reconstruct paleooceanic circulation along with detrital εNd that is an indicator of sediment provenance. It combines these with fish tooth rare earth element concentrations and sediment core XRF. Four key locations are utilised. Two on the Newfoundland margin in the West North Atlantic, and one from the high North Atlantic in the Labrador Sea, both idea1 locations to identify the potential outputs of North Atlantic deep-water formation. The fourth site is Demerara Rise in the Equatorial Atlantic, chosen to monitor changes in the dominant source of deep-water sources from the North or the South.

Abstract:
North Anggursi Sub-basin is one of the sub-basins in the North West Java Basin, located on northern of North West Java Basin. North Anggursi Sub-basin regionally was a sinistral pull-apart basin with northeast-southwest orientation which the direction of the extension was east west at Eocene. This subbasin is a back-arc basin during the Eocene to Oligocene. The dynamics of the North Anggursi Sub-basin were analysed using the palinspastic reconstruction method using 2D seismic lines which have east-west direction and biostratigraphy data. This analysis was carried out to determine the tectonic evolution to sub-basin tectonostratigraphy. Based on the results of subsurface mapping, the dominant type of geological structure in the study area is normal fault with NW-SE orientation. There was one unconformity phase during the Eocene. The forming of the North Anggursi Sub-basin began with the formation of Pre-Tertiary basement rock with an average rift of 6%. At Eocene began the syn-rift tectonic event with an average rift of 3%. After Eocene I, there was the deposition of Eocene II units which had compression with an average compression rate of 7% and then eroded. Syn-rift events began to end in the Oligocene with an average rift of 2%. Early Miocene began the post-rift phase with an average of rift of 1%. In Middle Miocene, there was an rift with an average of 1% and ended with Late Miocene by 0%. The intensity of rifting was very high during the Eocene, resulting in horst and half-graben morphology. The dynamics of the North Anggursi Sub-basin started from the Eocene to recent with three tectonic phases, they were the pre-rift that occurred during the Pre-Tertiary with the type of poly history basin of Continental Interior Sag (CIS), the syn-rift that occurred in the Eocene-Oligocene with the type of poly history basin of Continental Interior Fracture (CIF), and the post-rift the occurred in the Early Miocene-Late Miocene with the type of poly history basin of Continental Interior Sag (CIS).

Abstract:
The Labrador Sea formed during rifting between North America and Greenland beginning in the Early Cretaceous, with subsequent seafloor spreading from the Maastrichtian (chron C31) to Early Paleocene (chron C27n) that ended by chron C13 (earliest Oligocene). Early Cretaceous rifting resulted in accumulation of Alexis Formation basalt units and Bjarni Formation nonmarine and marginal marine clastic rocks. In the Late Cretaceous, extension focused further offshore as sag basin conditions formed across the shelf, with a basinwide transgression of Markland Formation shale and localized Freydis Member sandstone development. A Middle Paleocene to Early Eocene regression formed Gudrid Formation shoreline sandstone units, with correlative Cartwright Formation marine shale units. This was followed by an Early Eocene transgression of the Kenamu Formation and Middle Eocene Leif Member shoreline development. During the Late Eocene through Pleistocene, transgression took place once again at the base of the Mokami Formation, with subsequent development of the partly correlative shallow-marine sandstone units of the Saglek Formation.
