Major Sources of Ecuadorian Archaeological Obsidian and Provenience Assignment of Artifacts

Year: 1981

Type: article

Abstract: del Ecuador.Neutron .. .. activation analyses and x-ray fluorescence measurements strongly suggest that the Hullumica obsidian deposit is variable in composition with linear or nearly linear relationships between all measured elements.This behavior is very similar to that of obsidian from Borax Lake in California in the United States.Two other sources near the voliii cano Antisana, Yanaurco Chico and Quiscatola, have identical and nearly homogeneous chemical abundances.The two composition patterns, Hullumica and Yanaurco Quiscatola account for nearly all (96%) of a group of 126 obsidian artifacts measured in this and a previous study.The Hullumica source is the most prominent of the t\vO and accounts for about 75% of the artifacts.The sources are adequately distinguished by inexpensive non-destructive xray fluorescence measurements of Sr and Zr as well as the more definitive neutron activation analyses.
