“…Another set of artifact samples attributed to the CVF is present at Rose Spring in the Rose Valley, a N-S trending valley located just south of Owens Valley ~15 km northwest of the Coso Range [150]. The Rose Spring site, which was a locus of cultural activity multiple times during the past 2000 years [53,151], is located near the northern end of the Rose Valley and is the type site for the Rose Springs series of arrow points [152].…”

With the recent introduction of handheld instruments for field use, laser-induced breakdown spectroscopy (LIBS) is emerging as a practical technology for real-time in situ geochemical analysis in the field. LIBS is a form of optical emission spectroscopy that is simultaneously sensitive to all elements with a single laser shot so that a broadband LIBS spectrum can be considered a diagnostic geochemical fingerprint. Sets of LIBS spectra were collected for seven obsidian centers across north-central California, with data processed using multivariate statistical analysis and pattern recognition techniques. Although all obsidians exhibit similar bulk compositions, different regional obsidian sources were effectively discriminated via partial least squares discriminant analysis. Obsidian artifacts from seven archaeological sites were matched to their putative sources with a high degree of confidence.
