Object Description

The Erfkroon 2025 OSL samples consist of sands, silts, and gravels collected for the purposes of optically stimulated luminescence (OSL) dating. The samples are Pleistocene in age, and were collected from two locales in the Erfkroon study area (Area M, Area N). Sample counts are as follows: Area M=7, Area N=6. All samples are stored in copper metal tubing to prevent exposure to light until they can be prepared for dating at the Luminescence Dating Laboratory located at the University of the Fraser Valley, Abbotsford, British Columbia, Canada. 

Provenance

OSL samples were collected from two geological profile exposures located in the main eroded donga at the site of Erfkroon. The samples range in depth from ~80-270 cm below the modern surface.

User Comment
The samples will be run by Dr. Olav Lian at the Luminescence Dating Laboratory located at the University of the Fraser Valley in Abbotsford, British Columbia, Canada, in collaboration with PhD candidate, Ms. Sarah E. Morris at Simon Fraser University, Burnaby, British Columbia, and the National Museum of Bloemfontein. The dating results will be incorporated into Ms. Morris' PhD dissertation research as well as publications produced in collaboration with the National Museum of Bloemfontein (Dr. Will Archer) and researchers affiliated with Texas State University (Dr. Britt Bousman, Dr. Holly Meier).
