AN ENERGY-DISPERSIVE X-RAY FLUORESCENCE ANALYSIS OF OBSIDIAN ARTIFACTS FROM FOUR ARCHAEOLOGICAL SITES IN SOUTHEASTER NNEW MEXICO
Abstract
The source provenance of the artifacts is dominated by Jemez Mountains sources(Table 1and Figure1; see Shackley 2016). Cerro Toledo Rhyolite obsidianis available as secondary deposits in Rio Grande Quaternary alluviumat least to Las Cruces, but Valles Rhyolite (Cerro del Medio) has not been found south of Albuquerque, and only as a few small diameter samples(Church 2000; Shackley 2005, 2013, 2020).
