Geochemistry of Holocene coastal deposits (NW Germany): palaeoenvironmental reconstruction
Grundlage der vorliegenden Dissertation, die Teil eines interdisziplinären Projektes des ICBM und des Forschungszentrums Terramare ist, bilden neun Bohrkerne aus dem nordwestdeutschen Küstenraum. Die erbohrten Kerne erfassen die gesamten holozänen Ablagerungen und wurden in hoher Auflösung u.a. …

VOLCANIC EMISSIONS AND DISTAL PALAEOENVIRONMENTAL IMPACTS IN NEW ZEALAND
… these sites to examine the immediate short-term palaeoenvironmental impacts from volcanic tephra deposition. The methods used included pollen analysis, and the relatively new technique of Energy Dispersive X-ray Micro Analysis (EDMA) which investigated changes in sediment geochemistry to provide …

Geochemical and palynological signals for palaeoenvironmental change in south west England
… a geochemical technique for the investigation of palaeoenvironmental change in south west England. The method, EDMA (Energy Dispersive X-ray Micro Analysis), is a rapid, non-destructive analysis tool, capable of detecting a large range of geochemical elements. This research examines the most …

Plants as biotic indicators of Neogene palaeoenvironmental evolution in the Cape Floristic Region
Comparative biologists have refined the synthesis of molecularly dated phylogenies and ecological data into an important tool to reconstruct the evolution of species and biomes, and to unravel the history and role of abiotic determinants of diversity patterns (fire, climate, tectonism). This has …

Resolving abrupt palaeoenvironmental changes in a lake sediment sequence from Ioannina, northwest Greece
Palaeoenvironmental sequences from the Mediterranean have, for many years, been a cornerstone of our understanding of ecological responses to Quaternary climate change. Lake Ioannina (NW Greece) is one such archive, with a vegetation record which spans multiple glacial-interglacial cycles. This PhD …

Palaeoenvironmental change from the Hettangian to Toarcian in Moyeni (Quthing District), southwestern Lesotho
… this research aims to document Early Jurassic palaeoenvironmental and tectonic changes in this region. The upper Elliot Formation comprises very fine- to fine-grained sandstone units with either massive or with ripple cross-lamination, low-angle cross-bedding as well as sandy siltstone with …

PALAEOECOLOGY, PALAEOENVIRONMENTAL ANALYSIS AND THEIR APPLICATION TO SEQUENCE STRATIGRAPHY: LOWER CRETACEOUS, LUSITANIAN BASIN, PORTUGAL
Palaeoecological data can provide key information on depositional environments. This may be critical to the interpretation of marine sedimentary cycles and the recognition of ancient cycles and sequences. Although many recent studies have attempted to combine palaeoecology and sequence …

Analysis of dental pathologies in the Pliocene herbivores of Langebaanweg and their palaeoenvironmental implications
This study evaluates the extent of dental pathologies in several ungulate species from the Pelletal Phosphate Member (PPM) at Langebaanweg, and uses this analysis, along with stable isotope analyses, to obtain fresh insight into the local palaeoenvironment during the Early Pliocene.

Palaeoenvironmental investigations into the human-environmental interactions of prehistoric communities around loch of Stenness, Orkney
This palaeoenvironmental study explores the interactions of prehistoric communities with natural environments within the Heart of Neolithic Orkney (HONO), by analysing sediment sequences from the Loch of Stenness. This study focuses on the Mesolithic (10000 cal BC to 4100 cal BC) and Neolithic …

Middle and upper jurassic foraminifera and radiolaria of Scotland : an integrated biostratigraphical and palaeoenvironmental approach
… study is an integrated biostratigraphical and palaeoenvironmental analysis of foraminiferal and radiolarian distribution from all the major Middle and Upper Jurassic marine deposits of Scotland. These sampled sites are divided between two basins with Staffin Bay and Bearreraig Bay within the …

GEOARCHAEOLOGICAL AND PALAEOENVIRONMENTAL RECONSTRUCTION OF THE HOLOCENE CLIMATE-ENVIRONMENTAL-HUMAN NEXUS IN THEKURDISTAN REGION OF IRAQ
The geoarchaeological, multiscale approach performed in this research provides several new perspectives for the Holocene paleoclimatic and paleoenvironment reconstruction in the KRI Moreover, it enhances our understanding of the human responses and adaptation to climate, landscape, ecosystem, and …

Palaeoenvironmental and palaeogeographic reconstruction of the Tequixquiac Basin, Central Eastern Mexico: Mid to late Pleistocene environments
… 55 m lithostratigraphic sequence for multi-proxy palaeoenvironmental information. The main research objective was to develop a spatial and temporal Palaeogeographic and Palaeoenvironmental model for the study area the covered the late Pleistocene to early Holocene. The findings of the study, based …

A stratigraphical, sedimentologial and palaeoenvironmental analysis of holocene and present-day coastal sedimentation: Wigtown Bay, S.W. Scotland
Evidence of Holocene marine transgression and regression in South-West Scotland is exhibited in the stratigraphical record of present and former coastal deposits. Remnant areas of Holocene coastal (including marine) sediments are preserved at the head of marine inlets and estuaries along the …

Palaeoenvironmental reconstruction and geoarchaeology of the Cuatro Cienegas Basin, NE Mexico, from the late Pleistocene to the present
… a 15 m carbonate sediment core for multi-proxy palaeoenvironmental information and combined this with stable isotope, modern hydrological and geoarchaeological information in the Cuatro Cienegas Basin.

Glaciomarine sedimentation at the continental margin of Prydz Bay, East Antarctica : implications on palaeoenvironmental changes during the Quaternary
The Antarctic plays an important role in the global climate system. On the one hand, the Antarctic Ice Sheet is the largest freshwater reservoir on Earth. On the other hand, a major proportion of the global bottom-water formation takes place in Antarctic shelf regions, forcing the global …

Palaeoenvironmental reconstruction in South Africa's year-round rainfall zone using multiproxy geochemical analyses on lake sediments from Swartvlei
… Africa contain sediments with good records of palaeoenvironmental changes. Swartvlei is the largest of the lakes in the Wilderness Embayment and is connected to the Indian Ocean via an estuary. The lake is believed to have been formed during sea-level regressions in the quaternary, and …

The morphology, sedimentology and palaeoenvironmental significance of two pan-lunette clusters in the Southwestern Cape of South Africa
Two clusters of pans and associated lunette dunes are distinct landscape featurs in the Swartland and Agulhas Plain regions of the southwestern Cape of South Africa. While occurring in geographic proximity within the Winter Rainfall Region, each of the pan-lunette clusters is hosted by different …

Palaeoenvironmental reconstruction of late Holocene climate dynamics in Southwest Africa using a multi-proxy characterization of Namaqualand mudbelt sediments
… aims to create a catchment-integrated view of palaeoenvironmental conditions in the country's Winter Rainfall Zone (WRZ) and Southern Benguela region during the late Holocene, in order to establish the linkages between oceanic and terrestrial climate components. A multiproxy analysis was …
