Abstract. The sites of Hawelti–Melazo in the Tigray region northern Ethiopian Highlands is an archaeological hotspot related to D'mt kingdom (ca. 800–400 BCE). existence several monumental buildings, which have been excavated since 1950s, underline importance this area Ethio-Sabaean period. We investigated geomorphological and geological characteristics site its surroundings carried out sedimen...

Abstract This review paper discusses the basics of optically stimulated luminescence (OSL) phenomenon, phosphors for OSL, functional design OSL phosphors, and application areas such as radiation dose monitoring individual environmental, computed radiography medical dental diagnosis, dating, security, archaeological autoradiography drug discovery. Finally, future prospects phenomenon passive-typ...

Lake sediments in the Larsemann Hills contain a great diversity ofbiological and physical markers from which past environments can be inferred. In order to determine the timing of environmental changes it is essential to have accurate dating of sediments. We used radiometric (*loPb and I3'Cs), radiocarbon (AMS "C) and uranium series (2'*U) methods to date cores from eleven lakes. These were sam...

Dating the construction of dry-stone walls is challenging since such structures are typically built without any mortar that can be used for dating. Rock surface luminescence dating a developing method could advance chronological insights from constructed using techniques. This study explores rock by targeting two enclosure complexes and hut located in pastoral upland landscape Val di Sole, Ital...

Abstract The site of Nokalakevi, in western Georgia, has seen significant excavation since 1973, including, 2001, a collaborative Anglo-Georgian project. However, the interpretation largely rested on architectural analysis standing remains and relative dating deposits based study ceramics. Since 2013, Expedition to Nokalakevi collected diverse dataset derived from multiple scientific techniques...

In the Eurasian Upper Paleolithic after about 35,000 years ago, abstract or depictional images provide evidence for cognitive abilities considered integral to modern human behavior. Here we report on two abstract representations engraved on pieces of red ochre recovered from the Middle Stone Age layers at Blombos Cave in South Africa. A mean date of 77,000 years was obtained for the layers cont...

The lack of Late Pleistocene human fossils from sub-Saharan Africa has limited paleontological testing of competing models of recent human evolution. We have dated a skull from Hofmeyr, South Africa, to 36.2 +/- 3.3 thousand years ago through a combination of optically stimulated luminescence and uranium-series dating methods. The skull is morphologically modern overall but displays some archai...
