Osl dating sheffield
Many of these sites remain poorly dated, constraining their value in unraveling the paleoenvironmental evolution of the region.
Since this time, the system has fluctuated but generally strengthened (Siesser, 1977), but a detailed picture is lacking (Pether, 1994a,b; Roberts and Brink, 2002). Aeolianite and barrier dune construction spanning the last two glacial-interglacial cycles from the southern Cape coast, South Africa Quaternary Science Reviews 23, 1681-1698. Late Tertiary to Pleistocene onshore shallow marine and aeolian deposits have the capacity to fill these voids, but again the lack of a detailed and robust chronology (Pether, 1994a,b; Roberts et al., 2007a) hampers progress. The proposed project involves the application of Optically Stimulated Luminescence (OSL) dating. The Cenozoic sediments of the west coast, especially in the Saldanha/Langebaan environs, are richly endowed with archaeological and palaeontological remains, ranging in age from the Miocene to the Holocene. The diverse Mio-Pliocene fauna at the Langebaanweg phosphate quarry itself, the Early/Middle Pleistocene Hopefield site, where the partial cranium of early archaic Homo sapiens (Saldanha Man) was found (Singer and Wymer, 1968) along with ESA artifacts, and several Middle to Late Pleistocene sites have attracted international attention.
