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...

Assessments of the complexity of lithic technologies coming from different time periods, regions, or hominid species are recurrent features of the literature on Paleolithic archaeology. Yet the notion of lithic complexity is often defined intuitively and qualitatively, which can easily lead to circular arguments and makes difficult the comparison of assemblages across different regions and time...

The ex ca va tion at Klissoura was planned in 1992, as a joint-pro ject be tween the Ephoreia of Palaeoanthropology and Spe le ol ogy of the Min is-try of Cul ture of Greece and the In sti tute of Ar-chae ol ogy of the Jagiellonian Uni ver sity of Kra-ków, Po land. Our pri mary goal was to in ves ti gate the cir cum stances un der which the neolithisation of NW Peloponnese came about. For this ...

Research into the processes that form the archaeological record is an important component of archaeological practice because formation processes are a key link between the materials that archaeologists study and prehistoric societies that they seek to understand. Computational modeling is a comparatively new technology with potential to provide new insights into the dynamics of human societies,...

Studies of the African Middle Stone Age (MSA) have become central for defining the cultural adaptations that accompanied the evolution of modern humans. While much of recent research in South Africa has focused on the Still Bay and Howiesons Poort (HP), periods following these technocomplexes were often neglected. Here we examine lithic assemblages from Sibudu that post-date the HP to further t...
