Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)

Archaeometry, EarlyView.
ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...

Physical and chemical characterization of recycled glass sand for environmental restoration

Restoration Ecology, EarlyView.
Abstract Introduction We rely on coastal resources for food, water, and energy. However, over 75% of U.S. coastlines are eroding. Concurrently, the U.S. recycles less glass than other developed countries, landfilling hundreds of millions of tons every year.
