Optically stimulated luminescence (OSL) signals from quartz can be used to determine when
sedimentary archives were deposited. OSL dating uses the accumulation of energy stored in …

Whether during past climate stages or into a progressively warming world, changes in
precipitation constitute a key component of climatic change. Quantitative proxies for palaeo …

The Tibetan Plateau is the highest and one of the most demanding environments ever
inhabited by humans. We investigated the timing and mechanisms of its initial colonization …

Luminescence dating is used extensively to provide absolute chronologies for Late P
leistocene sediments. Nowadays, most optical dates are based on quartz optically …

Questions surrounding the chronology, place, and character of the initial human colonization
of the Americas are a long-standing focus of debate. Interdisciplinary debate continues over …

Different single-aliquot regenerative-dose (SAR) protocols have now been applied for some
years to quartz grains for determining the equivalent dose, in both dating and retrospective …

Radiocarbon dating of the earliest occupational phases at the Cooper's Ferry site in western
Idaho indicates that people repeatedly occupied the Columbia River basin, starting between …

Feldspar infrared stimulated luminescence (IRSL) signals saturate at∼ 2000 Gy, ie∼ 500–
700 ka (assuming a dose rate of 3–4 Gy/ka, typical for loess) and it is therefore theoretically …

Optical dating of sediment using optically stimulated luminescence has become important
for studying Earth surface processes, and this technique continues to develop rapidly. A …

Evidence increasingly suggests that sub-Saharan Africa is at the center of human evolution
and understanding routes of dispersal “out of Africa” is thus becoming increasingly …
