Abstract:
AbstractPermian strata in the British Isles crop out mainly in northern and central England but are extensive in the subsurface both on land and in several adjoining offshore areas. Their base is defined as in Smith et al. (1974) and their top is within red beds, overlying the Zechstein evaporites.We emphasize that both the base and the top of the nominally Permian rocks lie in continental strata almost devoid of stratigraphically useful fossils and that, accordingly, these boundaries are only doubtfully correlated with internationally acceptable biostratigraphic standards.Subdivision of British Permian strata into Lower and Upper series follows the traditional view summarized by Smith et al. (1974). The junction between the series is taken at the incoming of marine strata in northern England and adjoining offshore areas, and at approximately equivalent levels in continuous continental sequences elsewhere; recent limited palynological studies suggest that the early Permian-late Permian transition adopted here and in most of northwest Europe may be mid or late Kazanian or even Tatarian in age which is somewhat younger than the base-Kazanian/Ufimian position taken in more continuous marine sequences.There has been no comprehensive revision of the stratigraphy and nomenclature of early Permian strata in and around the British Isles since the work of Smith et al. (1974) and Rhys (1974), but these aspects of the early Permian continental deposits of several cuvettes and inland drainage basins in southwest Scotland were reviewed by Brookfield (1978) and the age of continental deposits in the Elgin area was reconsidered

Abstract:
Introduction. The Upper-Kama dialect is one of the varieties of the Komi language, which is rather common in the Afanasyevsky area of the Kirov region. The dialect is an intermediate idiom between the Komi-Permian and Komi-Zyryan languages. The purpose of the paper is to analyze the Komi-Permian and Komi-Zyryan components in the lexical system of the dialect. Materials and Methods. The material for the study was collected during dialectological expeditions to the area of residence of the Kirov Permians in 2002–2012. It was collected from native speakers with a high level of language competence. The research was carried out using descriptive, comparative and statistical methods. Results and Discussion. The vocabulary of the Upper-Kama dialect is heterogeneous. The most numerous group of words common for the Komi-Permian and Komi-Zyryan dialects is distinguished. Lexemes in the Upper Kama dialects and at a larger territory in the Komi-Zyryan language, but are absent in the Komi-Permian one. There is also a group of words which correspondences are recorded in the southern Komi-Zyryan dialects: Mid-Sysola, Luza-Letka and mainly in the Upper-Sysola one. On the territory of the Upper-Kama idiom there are the lexemes, which isoglosses cover the Upper-Kama and Komi-Permian dialects. However, there are not so many similar Komi-Permian-Upper-Kama isoglosses; most of them can be found in the Zyryan dialects. As a result of the analysis of the texts in the Upper-Kama dialect, it turned out that the overwhelming majority of lexemes are found in all varieties of Komi languages. Conclusion. The analysis of the lexical composition of the Upper-Kama dialect has shown that the specified idiom cannot be unconditionally attributed to the Komi-Permian language, since the correlation of the Komi-Zyryan and Komi-Permian lexical features in it is approximately the same.

Abstract:
The Paleozoic to Mesozoic grade ‘Protozygoptera’ is revised. It appears to be composed of two main lineages, namely the superfamily Permagrionoidea, and the Archizygoptera. The latter taxon forms a monophyletic group together with Panodonata (=crown-Odonata plus their closest stem-relatives). Therefore, the ‘Protozygoptera’ as previously understood is paraphyletic. Diagnostic characters of the ‘Protozygoptera’, Permagrionoidea, and Archizygoptera are re-evaluated. The Permolestidae is considered as a junior synonym of the Permagrionidae. The following new taxa are described: Permolestes sheimogorai new species, Permolestes soyanaiensis new species, Epilestes angustapterix new species, Solikamptilon pectinatus new species (all in Permagrionidae); Lodeviidae new family (for Lodevia); Luiseiidae new family (including Luiseia breviata new genus and species); Kennedya azari new species, Kennedya pritykinae new species, Kennedya ivensis new species, Progoneura grimaldii new species (all in Kennedyidae); Engellestes chekardensis new genus and species (in Bakteniidae); and Azaroneura permiana new genus and species (in Voltzialestidae). The Kaltanoneuridae and Oboraneuridae are revised. The evolution of protozygopteran Odonatoptera during the transition from the Permian to the Triassic is discussed. The larger taxa of the permagrionoid lineage apparently did not cross through the Permian–Triassic boundary, unlike the more gracile Archizygoptera. This last group shows a remarkable longevity from the late Carboniferous to the Early Cretaceous. It also presents a great taxonomic and morphological stability, with genera ranging from the Permian to the Triassic, and a wing venation pattern nearly unchanged from the late Carboniferous to the Late Triassic. The mass extinction at the end of the Permian period seemingly had a minor effect on these tiny and delicate insects.

O Grupo Guatá foi alvo de um estudo detalhado ao longo de toda a borda leste da Bacia do Paraná. Por meio da análise e descrição seqüencial de testemunhos e integração com dados de perfis, aproximadamente 100 poços foram analisados desde o norte do Estado do Paraná até a região centro-sul de Santa Catarina. As fácies foram agrupadas em sucessões de fácies, a partir das quais foram definidos os padrões de empilhamento do tipo progradante, retrogradante e agradante, que em conjunto definem os tratos de sistemas e conseqüentemente as seqüências deposicionais. Além disso, foi realizado um estudo de integração entre sedimentologia, icnologia e geoquímica, que definiu critérios para a identificação e interpretação de superfícies com significado estratigráfico regional. Isso possibilitou correlacionar com segurança poços ao longo de toda a borda leste da Bacia do Paraná e mapear a distribuição das seqüências deposicionais de 3ª.e 4ª ordens. O arcabouço estratigráfico revelou que as seqüências são formadas pelos tratos de sistemas transgressivo e de mar alto ou apenas pelo trato de sistemas transgressivo. Notou-se também que as seqüências estão diretamente vinculadas aos principais lineamentos estruturais da bacia. Interpreta-se que as seqüências 1, 2, 3, 4 e 5 foram soerguidas ao longo de toda a borda leste da Bacia do Paraná, com sua expressão máxima na região do Arco de Ponta Grossa. Esse soerguimento gerou uma discordância angular com expressão regional sobre a qual foram depositadas as seqüências 6, 7 e 8. A seqüência 8 é marcada por subsidência entre os Alinhamentos do Rio Piquiri e São Jerônimo-Curiúva, contemporânea à deposição dos tratos de sistemas transgressivo e de trato de mar alto.
The Guatá Group was target of a detailed study along the eastern border of the Paraná Basin. Using integration of core description and well logs, approximately 100 wells were analyzed in Paraná and Santa Catarina states. Facies were grouped in facies successions, which allowed the recognition of the progradational, retrogradational and aggradational stacking patterns and, consequently, system tracts and depositional sequences. Moreover, it was performed an integration among sedimentology, ichnology and geochemistry as a way to obtain criteria for identifying and interpreting regional stratigraphic surfaces. This allowed a detailed correlation along the eastern border of Paraná Basin and the mapping of third and fourth order sequences. The stratigraphic framework has revealed sequences formed either by the transgressive and highstand system tracts or just by the transgressive one. The sequences are directly linked to the main structural linements of the basin. It is interpreted that sequences 1, 2, 3, 4 and 5 were uplifted along the eastern border of the basin, with the maximum expression in the region of the Ponta Grossa Arch. An angular unconformity was generated and sequences 6, 7 and 8 were deposited later in time. Sequence 8 was affected by subsidence between the Rio Piquiri and São Jerônimo-Curiúva linements, contemporaneous to deposition of the transgressive and highstand system tracts.

Resumo: A típica Flora de Glossopteris, que caracteriza o registro paleobotânico do Permiano da Bacia do Paraná possui como um importante componente os lenhos fósseis coniferóides. Aqui foram tomadas sete localidades do estado de São Paulo, de afloramentos da Formação Irati e da Formação Teresina, para as quais se estudaram os lenhos coniferóides encontrados. Os espécimes variam dentre lenhos associados ao corpo primário preservado e lenhos sem associação ao corpo primário preservado (traqueidóxilos). São descritos três taxa com base nos espécimes de lenho com corpo primário associado (todos da Formação Irati):Solenopitys rusticanaMussa, AbietopitysKräusel sp. e Atlanticoxylon bortoluzzii (Guerra) comb. nov. Além da combinação nova proposta, é também sugerida uma emenda ao morfogênero AtlanticoxylonMussa. Para os traqueidóxilos foram descritos cinco taxa (os três primeiros da Formação Irati e os dois últimos da Formação Teresina): AgathoxylonHartig, BrachyoxylonHollick etJeffrey, ProtobrachyoxylonHoldensp. 1, ProtobrachyoxylonHoldensp. 2 e ProtobrachyoxylonHoldensp. 3. A taxonomia dos traqueidóxilosutilizou-se de uma abordagem quantitativa associada à tradicional taxonomia baseada apenas em caracteres qualitativos. Optou-se por não classificar os espécimes formalmente além do nível genérico pelo confuso histórico da taxonomia de traqueidóxilos fósseis e para evitar uma inflação no número de taxa.Há evidências de xeromorfismo nos lenhos estudados: falsos anéis e interrupções do crescimento. Estas corroboram, junto de evidências sedimentológicas, a hipótese de que os ambientes deposicionais das formações Irati e Teresina estão associados à predominância de um clima árido. As evidências xeromórficas podem ainda ser relacionadas à presença de hifas fossilizadas em alguns dos espécimes coletados em Angatuba (Formação Teresina). A proliferação de fungos nos lenhos junto das condições de estresse hídrico retrata um momento de "tempos difíceis" para tais plantas. A fenologia foliar das coníferas retratadas pelos lenhos descritos foi também analisada e aponta para a Formação Irati a presença de uma comunidade vegetal majoritariamente composta de coníferas perenifólias, mas com alguns elementos decíduos, enquanto na Formação Teresina os dados sugerem uma comunidade quase estritamente composta de árvores perenifólias, com menos elementos decíduos. Por fim, os lenhos retratados apresentam similaridades anatômicas com os espécimes encontrados em camadas correlatas do Grupo Ecca, da Bacia do Karoo
Abstract: The Glossopteris Flora, which characterizes the palaeobotanical record of the Permian of the Paraná Basin, has as a significant component the fossil wood related to the Coniferales. Here, seven localities in the state of São Paulo, from outcrops of the Irati Formation and Teresina Formation where conifer fossil wood are found have been studied. Among the specimens, there are both fossil wood with primary body associated and with no primary body associated (tracheidoxyls). The specimens with primary body associated (all from Irati Formation) are included in the following taxa: Solenopitys rusticanaMussa, AbietopitysKräusel sp. and Atlanticoxylon bortoluzzii (Guerra) comb. nov. In addition to the new combination, an emended diagnosis of the morphogenus AtlanticoxylonMussais suggested. The tracheidoxyls studied are included in the following taxa: AgathoxylonHartig, BrachyoxylonHollick etJeffrey, ProtobrachyoxylonHoldensp. 1, ProtobrachyoxylonHoldensp. 2 e ProtobrachyoxylonHoldensp. 3. The taxonomy of the tracheidoxyls was not only based on a tradicional qualitative analysis, but used a quantitative approach. We preferred not to formally classify the specimens beyond the generic level in face of the confusing history of fossil tracheidoxyl taxonomy and to avoid an inflation of the number of taxa. There is evidence of xeromorphy in the wood analyzed suchas false growth rings and growth interruptions. These adaptations corroborate, along with the sedimentological data, the hypothesis of arid conditions on the deposition of the Irati and Teresina formations. The xeromorphic evidence may also be related to the presence of fossilized hyphae on some of the specimens collected in Angatuba (Teresina Formation). The fungi proliferation on the wood along with the xeromorphic features indicate that such plants grew in "hard times". The analysis of the leaf phenology of the conifers studied here shows a community majorly represented by evergreen trees for the Irati Formation, but with some deciduous elements. On the other side, in the Teresina Formation, the analysis shows an almost entirely evergreen community, with less deciduous trees than in the Irati Formation. Finally, the wood studied here show anatomic similarities with the wood found in the Ecca Group, in the Karoo Basin

Abstract:
Carbonate reservoirs are usually diffcult to map and identify in seismic sections due to their complex structure, lithology and diagenetic frabrics. The Midland Basin, located in the Permian Basin of West Texas, is an excellent example of these complex carbonate structures. In order to obtain a better characterization and imaging of the carbonate buildups, an acoustic impedance inversion is proposed here. The resolution of the acoustic impedance is the same as the input seismic data, which is greatly improved with the addition of the low frequency content extracted from well data. From the broadband volume, high resolution maps of acoustic impedance distributions were obtained, and therefore the locations of carbonate buildups were easily determined. A correlation between acoustic impedance and porosity extracted from well data shows that areas with high acoustic impedance were correlated with low porosity values, whereas high porosities were located in areas of low acoustic impedance. Theoretical analyses were performed using the time-average equation and the Gassmann equation. These theoretical models helped to understand how porosity distributions affect acoustic impedance. Both equations predicted a decrease in acoustic impedance as porosity increases. Inversion results showed that average porosity values are 5% [plus or minus] 5%, typical for densely cemented rocks. Previous studies done in the study area indicate that grains are moderately to well-sorted. This suggests that time-average approximation will overestimate porosity values and the Gassmann approach better predicts the measured data. A comparison between measured data and the Gassmann equation suggests that rocks with low porosities (less than 5%) tend to have high acoustic impedance values. On the other hand, rocks with higher porosities (5% to 10%) have lower acoustic impedance values. The inversion performed on well data also shows that the fluid bulk modulus for currently producing wells is lower than in non-productive wells, (wells with low production rates for brine and hydrocarbons), which is consistent with pore fluids containing a larger concentration of oil. The acoustic impedance inversion was demonstrated to be a robust technique for mapping complex structures and estimating porosities as well. However, it is not capable of differentiating different types of carbonate buildups and their origin.

Abstract:
Les ostracodes, microcrustacés (Arthropoda), sont relativement abondants dans les archives paléontologiques. Sensibles aux variations paléoenvironnementales, la composition des assemblages et leur diversité sont d’excellents marqueurs des changements qui affectent le benthos marin néritique. Leur diversité est connue pour être fortement affectée par la crise biologique marquant la limite Permien-Trias, mais leur histoire à la fin du Permien moyen reste peu documentée.Près de 10 Ma avant la limite Permien-Trias, à la fin du Permien moyen, un important épisode d’extinction intervient, préfigurant le déclin de la biodiversité à la fin du Paléozoïque.L’étude systématique des échantillons prélevés le long des coupes de Chaotian (province du Sichuan, Chine) et de Penglaitan (province du Guangxi, Chine) a permis l’identification de 115 espèces d’ostracodes, dont 7 nouvelles. Le travail réalisé sur ces coupes constitue la toute première étude des événements de la fin du Permien moyen et du début du Permien supérieur s’appuyant sur l’observation des assemblages d’ostracodes. L’état de conservation des carapaces d’ostracode, étudié lors de ce travail, enregistre les effets de la fin d’un épisode de régression et le début d’un épisode de transgression au sommet du Permien moyen à Penglaitan. Les résultats s’avèrent en accord avec les données lithologiques et paléontologiques présentées dans la littérature, un modèle de reconstitution paléoenvironnementale basé sur les données de préservation des ostracodes est proposé.Une analyse critique de la qualité du jeu de données a permis d’évaluer l’influence des biais d’échantillonnage sur la représentativité du matériel fossile dans les études sur la paléobiodiversité et la paléoécologie. Les biais peuvent être corrigés par un traitement méthodologique approprié qui rend valide la comparaison des données de biodiversité. La richesse générique et spécifique décroît sensiblement au cours du Capitanien. Le passage du Permien moyen au Permien supérieur enregistre une augmentation de la richesse spécifique, malgré une faible diversité générique. L’ordre des Palaeocopida apparait ici affecté par une baisse de diversité générique et spécifique au Wuchiapingien inférieur. Si ces résultats ne permettent pas pour l’iPermiannstant de caractériser un événement global de renouvellement des communautés d’ostracodes, l’étude de matériel fossile provenant d’autres régions du monde permettra de définir l’ampleur des phénomènes observés
Ostracods, microcrustaceans (Arthropoda), are quite abundant in the fossil record. Highly dependent to palaeoenvironmental conditions, their diversity and the assemblages’ composition are good indicators of changes affecting neritic marine benthos. Ostracods are known to be deeply affected by the Permian-Triassic crisis, but their history is poorly documented for the end of Middle Permian.About10 My before the Permian-Triassic boundary, the end of Middle Permian is characterized by a major extinction episode, which could be the first step of end-Palaeozoic biodiversity drop.Systematic study carried out on Chaotian section (Sichuan Province, P.R. China) and the Penglaitan section (Guangxi Province, P.R. China) samples allowed the identification of 115 species, including seven new species. The work carried out on these two sections provides the first study of end-Middle Permian extinction event, based on the observation of ostracod assemblages.Study of carapace preservation at Penglaitan section, highlighted the end of a regression phase and the beginning of a transgression phase at the top of Middle Permian. These results are relevant with lithologic and palaeontological data from literature. Thus, a palaeoenvironmental reconstruction model has been proposed, based on ostracod preservation data.An estimation of sampling bias consequences on fossil dataset representativeness in palaeobiodiversity and palaeoecology studies was realised. These biases could be corrected by an appropriate methodology allowing comparisons of biodiversity datum. Biodiversity data reveals a decrease of generic and specific richness during Capitanian. Specific richness increased passing the Middle-Upper Permian boundary. Palaeocopida order seems here affected by a generic and specific richness decline at basal Wuchiapingian. If these results do not allow for the time being to characterize a global ostracod turnover, further studies on material from other regions in the world will allow defining the extent of the observed phenomena

Abstract:
In northern South America, Upper Palaeozoic strata were deposited extensively over peri-cratonic areas associated with restricted seas located between Laurentia and Gondwana, in equatorial Pangea. In many places the successions are rarely exposed, and so are poorly documented; this is largely the result of extensive weathering and dense vegetation in the tropical Andes. However, these strata do contain significant information for palaeogeographic and palaeoclimatic reconstructions, and our understanding of the evolution of northern Gondwana and the finally assembly of Pangea. The main objective of this thesis is the study of Permian carbonates in the Venezuelan Andes, their sedimentology, geochemistry, diagenesis and petroleum potential. The Palmarito sediments were deposited on a carbonate ramp that dipped basinwards towards the north facing the open ocean. The formation evolved from the underlying fluvial (Sabaneta Formation) through tidal-flat to mid-outer ramp deposits, with all facies recording a well-developed cyclicity. These strata fill an important gap in the regional palaeogeography and hence have revealed important implications for the palaeoclimate and palaeoceanography of the time. The results of this study of Palmarito strata have significant implications for the palaeogeography of this Permian time. From the facies analysis of the Palmarito Formation, new evidence has been provided for a central Pangean seaway. Furthermore, isotope analyses have improved the time-frame for the succession from 87/86Sr data, and in addition, the long-term stratigraphic trends in the δ13C and δ18O data have permitted interpretations of the climatic and oceanographic controls on Permian carbonate deposition. Moreover, metre-scale cyclicity shows the patterns of short-term controls on sedimentation, where autocyclic and allocyclic processes affected deposition and the vertical stacking of facies. An analysis of the diagenesis of the Palmarito carbonates shows several stages of cementation and alteration, although the strata are mainly fine-grained and coarse cements are rare. Finally the elements of the petroleum system for the Palmarito have been considered for the succession and as a result, it can be proposed that, firstly, fractures in finer-grained facies have the potential to provide reservoir rocks, and secondly, that although high values of Tmax have been obtained from rock-eval analysis from one locality, Palmarito strata do have the potential to form source rocks. Further investigation is required to ascertain the actual hydrocarbon potential of the Palmarito. The high content of finer-grained facies with low permeability provides the Palmarito strata a high potential to perform as a seal, as well as possibility to develop stratigraphic traps.

Abstract:
The British Permian Productidina have not been revised in detail since 1858. In the present study some 2000 specimens from 29 localities in north east of England have been collected and prepared in the laboratory and used together with museum collections. The fauna consists of four species of Strophalosia, one new species of Eostrophalosia, six species of Heteralosia (four new), three species of Craspedalosia (one new), two species of Howseia, four species of Horridonia (one new) and two species of Spinohorridonia new genus. The Strophalosiacea and Horridoniinae are divided according to a new classification produced in this research. British Permian productidinid species are often strongly variable. Some variants suggest possible sexual dimorphism while others are probably of ecological forms. The fauna as a whole is unique and exclusive to the Upper Permian Zechstein Sea. The British Permian fauna shows major radiation periods during the early EZla Ca and early EZlb Ca. In conjunction with these radiations, the Productidina become divided into two distinct assemblages, marking two biozones introduced in this thesis, the Horridonia horrida and Strophalosia excavata biozones. Little is known of the Malaysian Permian Productidina. They comprise one species each of Strophalosia, Craspedalosia, Institella, Antiquatonia, Reticulatia, Echi- noconchus, Linoproductus, Siepanoviella, Striatifera, Liosotella (with new species), Marginifera?, Paucispinifera, Retimarginifera (with new species) and Costispinifera, two species of Dictyoclostus, Waagenoconcha and Echinauris and three species of Cancrinella. Lower Permian productidinids are associated with Artinskian fusulines and show links with the South Tethyan cold water fauna. Upper Permian producti dinids contain a mixture of North Cathaysian elements and the warm South Tethyan lyttoniid fauna. Variation occurs within some of the Malaysian species, but owing to lack of material, no final deductions can be made. Similarly, although significant differences are observed in Malaysian productidinid distributions, tabulation of biostratigraphic zonation is left until more data is available.

Introduction -- Australian ð¹³Corg-isotope profiles about the Permian-Triassic (P/TR) boundary -- Strontium isotope seawater curve in the late Permian of Australia -- ð¹³Cco₃ AND ð¹⁸Oco₃ seawater profiles through the Permian-Triassic of Australasia -- Paleomagnetic stratigraphy about the Permian/Triassic boundary in Australia -- Synthesis.
The Permian-Triassic boundary mass extinction is the largest in the Phanerozoic and therefore is the major event in the Phanerozoic. The mass extinction cause is problematical but studying global geochemical and geophysical signatures about the Permian-Triassic boundary can provide insights into the cause of the mass extinction. Global events about the Permian-Triassic boundary are marked by changes in: ð¹³C values of carbon ; ⁸⁷Sr/⁸⁶Sr in unaltered marine calcite ; magnetic polarity. -- This study aims to identify these features in the sedimentary record and to test the ca libration of the Australian biostratigraphical schemes to the global geological timescale. The following features are found in the Permian-Triassic sediments of Australia: a ð¹³Corg in Total Organic Carbon excursion in 12 marine and nonmarine sections from Northwest to Eastern Australia ; a ⁸⁷Sr/⁸⁶Sr minimum in a composite section mainly from the Bowen Basin ; a magnetic polarity reversal in the Cooper Basin, central Australia. The Australian sections are thus time correlated, as follows: The negative ð¹³Corg excursion indicates the Permian-Triassic boundary and occurs: 1) in Eastern and Central Australia at the change from coal measures to barren measures with red beds at the beginning of the Early Triassic coal gap; 2) in Northwest Australia about the boundary between the Hyland Bay Formation and the Mount Goodwin Formation in the Bonaparte Basin and at the boundary between the Hardman Formation and the Blina Shale in the Canning Basin. The base of the negative ð¹³Corg excursion lies at or near the base of the Protohaploxypinus microcorpuspalynological zone. The ⁸⁷Sr/⁸⁶Sr minimum determined about the Guadalupian/Ochoan stage boundary in North America is found in the Bowen Basin about the boundary between the Ingelara and Peawaddy Formations. The ð¹³Corg excursion in the Cooper Basin is near a magnetic reversal within the Permo-Triassic mixed superchron. The implications of these findings include: confirmation of the traditional placement of the Permian-Triassic boundary at the coal measures/barren measures with redbeds boundary in Eastern Australia ; the linking of the the Permian-Triassic boundary to a mass extinction of plant species on land and the beginning of the Triassic coal gap indicated by the Falcisporites Superzone base that is coincident with the negative ð¹³Corg excursion ; a mass extinction causal model that links the ⁸⁷Sr/⁸⁶Sr minimum determined about the Guadalupian/Ochoan stage boundary to a fall in sealevel that led to changing global environmental conditions. The model invokes greenhouse warming as a contributing cause of the mass extinction.

Abstract:

The Colorado Cheyenne 3D seismic survey in this thesis project is located in Cheyenne and Kiowa counties in eastern Colorado and features the Las Animas Arch. The scope of this project aims to expand the understanding of the processes and products of salt weld development. Throughout the survey, lateral variability of the Nippewalla strata within the Permian section is observed in both seismic and well data and generally is a result of dissolution of the Blaine or the dissolution of the Cedar Hills.

In this project, structural and stratigraphic elements were seismically mapped and interpreted with a focus on salt dissolution and welding. Overall, the characteristics of the dissolution in the strata covered by the 3D seismic survey of this study can be separated by a centrally-located dissolution front with the western half of the area having the lower Blaine halite removed by dissolution and the eastern half having the lower Blaine halite preserved. Dissolution of the upper Blaine halite is pervasive through the study area, especially within the western region due to remnant salt.

The eastern half of the survey is also affected by the dissolution within the Cedar Hills Formation. Unlike the Blaine, the amount of dissolution that occurs in the Cedar Hills seems fairly consistent, removing almost the complete formation or no dissolution at all.

This thesis is intended to serve as an initial investigation of the structural and stratigraphic relations due to dissolution of the Permian salts. Numerous additional questions remain beyond the scope of this thesis.
