Science, 1978•science.orgIn 1975, archeological surface surveys of trade routes located again a pre-Hispanic obsidian
source in central Mexico first reported in 1902. Initial trace element studies of the Pared�n
source through an analysis by neutron activation have been compared with similar studies
of the obsidian found at Chalcatzingo 150 kilometers from the source. These comparisons
indicate that obsidian from Pared�n, rather than Otumba, was of primary importance during
the Early Formative in central Mexico.
