Uncertainties surround the timing of modern human emergence and occupation in East and Southeast Asia. Although genetic and archeological data indicate a rapid migration out of Africa and into Southeast Asia by at least 60 ka, mainland Southeast Asia is notable for its absence of fossil evidence for early modern human occupation. Here we report on a modern human cranium from Tam Pa Ling, Laos, ...
Distribution of radionuclides in the soil samples, Infra-red stimulated luminescence dating techniques, electrical conductivity, pH measurements and grain size analysis of soils of the region between the Ganga and Yamuna Rivers (in the Upper Gangetic plain) have been studied. Soil characteristics are highly sensitive to climate changes and the degree of soil development indicated by higher thic...
The success of optically stimulated luminescence (OSL) dating relies to a large extent on suitable characteristics the analysed mineral, in this case quartz. Previous OSL Quaternary sediments Scandinavia has shown that quartz vary widely across region, resulting studies with varied success. aim study is provide an overview Sweden and Norway, evaluate their effect results discuss underlying caus...
Newly obtained ages, based on electron spin resonance combined with uranium series isotopic analysis, and infrared/post-infrared luminescence dating, provide a minimum age that lies between 397 and 525 ka for the hominin mandible BH-1 from Mala Balanica cave, Serbia. This confirms it as the easternmost hominin specimen in Europe dated to the Middle Pleistocene. Inferences drawn from the morphol...
Abstract The kinetics of expansion in ceramic materials due to rehydration and rehydroxylation was investigated since the early XX century as a cause crazing glazed ceramics. Since then, study mass gain has been studied extending monitored times modeling involved processes. In last 20 years, interest this process grew its possible application dating field, supporting well-established techniques...
