Object Description
These samples consist of plaster-jacketed micromorphology blocks collected from the site of Erfkroon. The blocks consist of Pleistocene-age sands, silts, and gravels.The blocks are to be embedded with a polyester resin, then turned into petrographic thin sections for micromorphological analysis.
Provenance
The micromorphology blocks were collected from five geological exposures in an eroded donga consisting of ancient overbank and fluvial sediments in the Erfkroon study area (Study Areas M, Upper F, N, Efkroon Terrace, and "Dating Profile").

User Comment
The micromorphology blocks will be shipped to the Geoarchaeology Laboratory at Simon Fraser University, Burnaby, British Columbia, Canada, for embedding and additional analyses, including micromorphological analysis of thin sections and micro FTIR analysis. PhD Candidate Sarah E. Morris will conduct the analyses as part of her PhD dissertation research and in collaboration with the National Museum of Bloemfontein.
Collector Comment
Micromorphology blocks were collected over the course of three field seasons at Erfkroon (2017, 2018, 2025) by Ms. Sarah E. Morris, PhD candidate at Simon Fraser University, Burnaby, British Columbia Canada. The most recent collection occurred between June and July 2025. Samples are currently being held at the National Museum of Bloemfontein Florisbad Quaternary Research Station until they can be shipped to Simon Fraser University for further processing and analysis. Previously, blocks from the 2017 and 2018 field seasons were processed by Ms. Morris for micromorphological analysis. Those results were presented in her MA thesis at Texas State University (Morris, 2019). Preliminary results from that study are also published in Bousman et al. (2023).
