The chemistry of mafic volcanic rocks and minor intrusions erupted on continents can be used to define the composition and history of subcontinental asthenospheric and lithospheric mantle domains. We have produced new and collated published data for Antarctica in order to identify mantle domains beneath the continent. Suitable material archived at the British Antarctic Survey, Cambridge, the result of previous geological research, was sampled and prepared for petrographic and geochemical analysis in the intervening period between field collection and sample arrival in the United Kingdom. Field information, petrography and raw geochemical data obtained from XRF (X-ray fluorescence), ICPMS (Inductively coupled plasma-mass spectrometer), TIMS (Thermal Ionization Mass Spectrometer), Ar/Ar analysis and Electron Microprobe analysis of rock samples collected from Palmer Land and Graham Land was used to define a geochemical profile of crust/mantle architecture beneath the Antarctic Peninsula.

Initial work during the 2001/2002 field season commenced with reconnaissance and sampling in northeast Palmer Land. Over a two month period, outcrop from the Welch Mountains to the Eternity Range was visited, the geology described, and mafic dyke samples collected for analysis. This was followed by a further two months based on the ship HMS Endurance, carrying out helicopter assisted sampling of numerous islands and coastal localities along the western and eastern margin of northern Graham Land. Approximately 200 rock samples (400kg of dyke and host rock at Palmer land and 80kg at nine localities in Graham Land) were collected.

A geodatabase of 186 published Quaternary marine and terrestrial dates relating to the Last Glacial Maximum (LGM) glaciation and ice retreat, which capture the dynamics and retreat of the Antarctic Peninsula Ice Sheet (APIS).

The collection consists of over 1 tonne of rock samples from the Theron Mountains, with an emphasis on the mainline of the enscarpment, which was reached by climbing the scree slopes at the base of the cliffs or by traversing the skyline, during the 2004/2005 field season.

Field observations made during the 2004-2005 field season, using such features as sill steps, sill bridges, orientated phenocrysts and asymmetric structures to determine regional magma flow directions in the Theron Mountains. A full photographic record of the cliffs was made at a transit of 1km out from the cliffs.

The dataset comprises of chronostratigraphic data from the Fildes Peninsula, King George Island, South Shetland Islands. The data have been used to constrain deglaciation and climate-glacier dynamics on the Fildes Peninsula. These data include C-14 density probability phases. Data was compiled with with Potter Peninsula and King George Island data and a non-parametric phase model applied.

The dataset comprises of sedimentological, geochemical, biological and chronological data from a sediment core record extracted from Kiteschsee Lake sediment, Fildes Peninsula, King George Island, South Shetland Islands. We undertook multi-proxy analyses (diatom, grain size, geochemical and sedimentological) on a 77 cm-long sediment record extracted from the flat-bottomed eastern basin depocentre of Kiteschsee Lake and compared data obtained with published lake records from the Fildes Peninsula.

Rock samples were collected from the northern LeMay Range, southern Douglas Range and the Lully Foothills of Alexander Island during the 2004-2005 field season, and transferred to the Open University (OU) via the British Antarctic Survey. Samples were stored in the OU rock store during preparation for isotopic work.

Key geological boundaries were identified and mapped onto aerial photos and satellite images.

The dataset comprises of chronostratigraphic data from the Fildes Peninsula, King George Island, South Shetland Islands. The data consists of Radiocarbon (C-14) ages, which were obtained by Accelerator Mass Spectrometry (AMS) dating of marine mollusc shells, terrestrial mosses and seaweed layers embedded in sediments, and Cosmogenic Helium-3 (He-3) nuclide surface exposure dating (CSED). The data have been used to constrain deglaciation and climate-glacier dynamics on the Fildes Peninsula.
