Full textAbstract:
Salt Core DV93 -1, from Badwater Basin in California's Death Valley, spans the past 192 ka. An analysis of fossil palynomorphs from 151.8 m (ca. 166 ka) to 103.5 m (ca. 114 ka) delimits four pollen zones. Zone 1, the "cheno -am" zone (151.8 to 143.5 m depth, 166 -154 ka), contains high percentages of Chenopodiaceae /Amaranthus pollen, and correlates with marine Oxygen Isotope Stage (OIS) 7. Zone 2, the juniper zone (143.5 to 117.3 m, 154 -124 ka), correlates with OIS 6 and contains high percentages of Cupressaceae pollen and low percentages of Ambrosia pollen. A simultaneous drop in juniper and increase in oak (Quercus) pollen, followed by replacement of Artemisia with Ambrosia, occurs at the Zone 2 /Zone 3 (oak zone) boundary (124 ka), corresponding to OIS Termination II warming. Zone 4, the Asteraceae zone (108.8 to 103.5 m, 119 -115 ka), contains higher percentages of Asteraceae and cheno -am pollen, indicating further warming.

Full textAbstract:
The "desertification" debate surrounding the Karoo Biome of South Africa has recently inspired much research in this region. The preservation of pollen in middens in arid environments from different parts of the world has great potential for the reconstruction of past vegetation. A lodge of the bush karoo rat (Otomys unisulcatus) was excavated near Prince Albert, South Africa, and the high numbers of well-preserved pollen grains was analysed. The vegetation reconstruction suggested that there was a decline in grasses over the whole sequence, while the vegetation experienced several short-term fluctuations throughout the time period. The ages within the lodge were uncertain, although the material is likely to be modern. The palynological analysis appear to be reliable and corresponds relatively well with other studies. The lodges of these species could therefore provide an exciting new source of historical pollen in the arid regions of southern Africa.

Full textAbstract:
Palynological and stratigraphic investigations have been conducted on sediment cores for three sites in Lothian Region, Scotland: Balgone House, Broxmouth and Corstorphine. All phases of the Lateglacial period, as far as they are manifested in the Lothians at the sites studied, have been investigated with particular reference to the Younger Dryas, the main Interstadial, or Allerod, and also the evidence for the colder conditions that preceded it which are presumed to represent Older Dryas-type vegetation. Further light has been cast on the development of the Postglacial broad - leaved forests. The Cambridge computer program POLLDATA MKV was used to perform the necessary calculations and controlled a graph plotter to generate pollen diagrams. A series of subroutines is described that translated the calls to the Cambridge graphics subroutine library. This may serve as a model for other installations. Objective numerical zonation methods are applied to the pollen data. These methods are used not only to zone the pollen series but also to aid in the generation of hypotheses regarding vegetation changes. Chemical analyses of the sediments from Balgone House were undertaken. The results obtained are at variance with those from published work and it is proposed that the reason is that the chemical pre-treatment of samples employed locally may be less efficient in leaching the cations from the mineral fraction.

Full textAbstract:
Tanzania is one of the East African countries where rich hydrocarbon accumulations are starting to be discovered in both onshore and offshore sedimentary basins, although there is currently little research that has been published in relevant research areas of geology, micropalaeontology or hydrocarbon prospectivity. The hydrocarbon reserves discovered so far are mainly gas, and these have been found in Cretaceous and Cenozoic reservoirs that provide signatures of multi-source rock origins that demonstrate promising future prospects. This thesis presents a series of studies focussing on improving our understanding of the (bio)stratigraphy and hydrocarbon source rock potential of Cretaceous-Cenozoic sediments of Tanzania. The samples studied have unfortunately yielded impoverished organic-walled microfossil (palynomorph) assemblages, and thus the biostratigraphic analysis has formed a smaller component of this project than originally intended. The main aspect of the research undertaken has thus focussed on analysing organic matter composition (palynofacies analysis) and quality (organic richness, kerogen typing), in order to provide interpretations of the palaeoenvironmental conditions prevailing at the time of sediment deposition and hydrocarbon source potential. The hydrocarbon potential has also been examined by undertaking assessments of the thermal maturity of the host sediments using vitrinite reflectance measurements in order to construct thermal histories and burial models for the several of the study locations. This study examines three hundred Cretaceous-Palaeogene cutting samples from three boreholes drilled on the continental shelf (the shallow offshore basin sites Msufi # 1, Mtiki # 1 and Mkongo # 3), one hundred Cretaceous cutting samples from one well from the deep offshore basin (Mvule # 1), and twenty-nine Cretaceous core samples from shallow boreholes from Tanzania Drilling Project (TDP) sites 21, 24, 36 & 37.Biostratigraphic results are limited, with the three shallow offshore basin wells proving largely barren of palynomorphs. The samples from the deep offshore basin (Mvule #1) produced the highest species richness, and although lacking many age-diagnostic taxa, palynological analysis has permitted the recognition of three dinocyst-based bioevents, using first downhole occurrences of taxa, as is appropriate for borehole studies. The four TDP boreholes yielded very restricted palynological assemblages, but a series of downhole dinocyst bioevents have been recognised in the core material, and although not defined using definitively age-diagnositic taxa, the events have been dated by correlation with existing calcareous microfossil biozonations. The sedimentary organic matter (palynofacies) analyses of the onshore and shallow offshore basin sites indicates the sediments studied were deposited in oxic open shelf conditions in close proximity to land, due to the high supply of terrestrial input diluting other palynomaceral components. Certain stratigraphic intervals were subject to periodic lowering of the oxygen conditions. The samples from the deep offshore basin well (Mvule #1) indicates a more marine-influenced setting. Overall, all samples are dominated by Type III kerogens, which are indicative of gas-prone source rocks. The organic richness (total organic carbon: TOC) results range from 0.1% to 3.4% TOC, demonstrating good source potential. In particular, the TOC values for the shallow offshore basin wells are as follows: for Msufi # 1, TOC ranges from 0.3-0.8%; for Mtiki #, 0.1-3.0%; for Mkongo # 3, 0.4-1.1%, and for the deep offshore well Mvule # 1, the TOC values range from 1.0-3.4%. Thermal maturity of the sediments was assessed using vitrinite reflectivity (Rv %), and values range from 0.3-3.4% Rv, indicating mature to post-mature maturity levels, and thus that the sediments studied have reached values appropriate for hydrocarbon generation. Computer modelling of the burial histories of the successions studied reveals that they have entered the window for early liquid hydrocarbon generation and reached the stages for wet-dry gas generation.

Full textAbstract:
Palynological data from a new core from Tswaing Crater Lake within the savanna
biome of South Africa contributes to a better understanding of vegetation and
climate dynamics during the Holocene. A 650cm sediment core section TSW1,
with 65 samples and fourteen AMS 14C dates, covers a time period between ca
10000-2000 cal yrs BP. No pollen data are available from the lower part of the
profile (600-800cm) due to palynomorph destruction, but a single sample with a
low number of pollen grains gives a glimpse into a presumably very dry time
period at ca11300 cal yrs BP. A warm and dry early Holocene (ca 9000-7500 cal
yrs BP) is evidenced by high pollen percentages of Asteraceae, Tarchonanthus
and Dichrostachys. The mid Holocene phase from ca 7500-4000 cal yrs BP is
characterised by an increase of Burkea, Combretaceae and Podocarpus as well as
aquatics and swamp plant pollen. This suggests warm sub-humid conditions and
local moisture during this time interval. A short-term dry period occurred ca 4000
-3600 cal yrs BP characterized by a significant decline of most tree pollen
including Podocarpus, whereas Poaceae pollen increased slightly. From ca 3600 -
2000 cal yrs BP tree pollen percentages gradually increased and the presence of
Spirostachys pollen suggests a return to warm sub-humid conditions. The upper
part of the profile above a depth of 150cm shows disturbances due to salt mining
and was therefore not sampled. The palaeoclimatic interpretation of the pollen
fluctuations was supported by PCA (Principal Components Analysis). From
around ca 1800 cal yrs BP additional samples were studied in this project in
comparison to the previous study of Scott to improve the resolution. The climatic
investigation from the Tswaing pollen record of the current study supports the climatic interpretations which were inferred from the biomarker analysis by
Kristen et al., 2009. A regional comparison between the current Tswaing pollen
profile and pollen records from Wonderkrater and Lake Eteza was done in the
frame of the current study. The general palaeoclimatic changes recorded from
Tswaing pollen sequence are consistent with the pollen evidence inferred from
Wonderkrater which can attributed to regional changes in eastern South Africa.
These trends differ from those in lake Eteza, especially during the early Holocene,
which might be explained as a consequence of the generally more humid climate
in the coastal plain of KwaZulu-Natal.

The aim is to gather pollen sequences and derive from them synthetic information on past species distribution and Holocene vegetation history. Lonicera nigra was selected as a model taxa. The phylogeographic hypothesis that its Alpine and Carpathian populations survived the LGM in separate refugia is supported only by the Late-Glacial record. This shrub migrated rapidly from southern to central Europe during the warm oscilations of the Late Glacial. The synthesis of vegetation history was produced by applying the REVEALS model, which can filter out following factors influencing the relationship between pollen and vegetation: pollen taphonomy, pollen productivity and pollen dispersal. It was necessary to calculate and test those parameters, so the goals were partly methodical. Pollen productivity estimates are calculated within the Relevant Source Area of Pollen, which is influenced by vegetation structure. Subsequent validation of those values in the area of the REVEALS model 10000 km2 and selection of additional values for lacking taxa created the best set of parameters for the study area. The source fossil dataset for purposes of this synthesis is the newly developed Czech Quaternary Pollen database (PALYCZ). Non-direct multivariate analysis of pollen percentages including all taxa revealed a similarity...
