Object Description

ERF-25-Bulk Geochem Samples refers to bulk sediment samples comprised of ancient (Pleistocene) sands, clays, and gravels collected from three geological exposures in the Erfkroon study area. Samples were extracted from various depths below surface, ranging from ~80-370 cm below the modern surface. These samples will be utilized for geochemical and sedimentological analyses, including: laser grain size (texture) analysis, magnetic susceptibility analysis, sedimentological carbon isotope analysis, carbon loss on ignition analysis, and spectroscopic analyses including XRF, FTIR, and Micro-FTIR.

Provenance

Bulk geochem samples were extracted from mid to late Pleistocene-age fluvial and overbank sedimentary deposits. These were extracted from exposed geological profiles at study areas Upper F, Area M, Area N, and Area B. Sample counts from each area are as follows: Upper F = 13 samples; Area N = 16 samples; Area M = 29, Area M Profile 5=9, Area B=3 (total sample count=70).

User Comment
The bulk samples will be utilized for geochemical and sedimentological analyses by Sarah Morris, PhD candidate at Simon Fraser University in British Columbia, Canada. Specifically, she will conduct these analyses in the specialized geoarchaeological laboratory on SFU campus, which contains the necessary equipment (sedimentological analysis - laser sizer grain size analysis, magnetic susceptibility, and spectroscopy - XRF, FTIR, micro-FTIR). The samples are to be run at the Geoarchaeology Laboratory at Simon Fraser University, Burnaby, British Columbia. Ms. Sarah E. Morris will oversee the analyses as part of her PhD dissertation research and in collaboration with the National Museum of Bloemfontein.
