Chapter 7 aims to provide a comprehensive description of the basalt assemblages, a major component of the archaeological horizons of Gesher Benot Ya‘aqov. Analyses consist of taphonomic, morphological, technological, and typological observations, which enable characterization and reconstruction of the operational sequences of basalt. These involve percussive tools (anvils, percussors, and pitted stones) and the use of giant cores for the production of large flakes, which required minimal modification for their transformation into bifaces.
