Introduction: Equilibrated lithic clasts in unequilibrated chondrites probably represent thermal metamorphism in the early solar system before or during accretion of chondritic parent bodies. Lithic clasts with equilibrated features are rare in unequilibrated chondrites and their origins are not well-understood [1]. Recently, we observed an unusual lithic clast with thermal-metamorphosed featur...

A metamorphosed lithic clast was discovered in the CM chondrite Grove Mountains 021536, which was collected in the Antarctica by the Chinese Antarctic Research Exploration team. The lithic clast is composed mainly of Fe-rich olivine (Fo62) with minor diopside (Fs9.7–11.1Wo48.3–51.6), plagioclase (An43–46.5), nepheline, merrillite, Al-rich chromite (21.8 wt% Al2O3; 4.43 wt% TiO2), and pentlandit...

of chipped stone tools were obtained by direct procurement from bedrock and transported geologic sources, through exchange, and by means of scavenging stone artifacts from archaeological deposits. Recycling and reuse of found stone artifacts has been historically documented (Amick 2007; Ascher 1968; Gould et al. 1971; Hill 1938; Sedig 2010; Tindale 1965) and identified in the archaeological rec...

Reason for Corrigendum: In the original article (Palladino et al., 2015), there was an error in Figure 1. The vertical axis of the qualitative plot reported erroneously “ratio of juvenile to lithic materials in deposits outside of depression”. The correct wording is as follows: “ratio of juvenile to total (i.e., juvenile+lithic) materials in deposits outside of depression”. In fact, as it was r...

This paper aims to update the information available on the lithic assemblage from the entire sequence of TD6 now that the most recent excavations have been completed, and to explore possible changes in both occupational patterns and technological strategies evidenced in the unit. This is the first study to analyse the entire TD6 sequence, including subunits TD6.3 and TD6.1, which have never bee...

Despite the numerous studies proposing early human population expansions from Africa into Arabia during the Late Pleistocene, no archaeological sites have yet been discovered in Arabia that resemble a specific African industry, which would indicate demographic exchange across the Red Sea. Here we report the discovery of a buried site and more than 100 new surface scatters in the Dhofar region o...

Marcel Otte recently argued (In "Comments on Mezmaiskaya, North Caucasus", Eurasian Prehistory, this issue) that the Early Upper Paleo-lithic (EUP) at Mezmaiskaya Cave can be defined as Aurignacian (versus Golovanova et al., 2006). This raises an old methodological problem concerning the correct use of scientific terms and the definition of the Aurignacian. Lithic definitions such as Aurignacia...
