Description :
This paper documents the first application of laser Raman and Fourier transform infrared vibrational spectroscopic techniques (Raman/FT-IR) to the analysis of silcrete. Analyses are undertaken at a reconnaissance level on bulk silcrete samples of varying ages, drawn from a range of geomorphological settings across the Kalahari Desert. The extent to which it is possible to identify the environment of cement precipitation and transformation is discussed.
