	title = {INAA and Obsidian Hydration Dating of Mayan Bladelets from Cahal Pech, Belize, C.A.},

	abstract = {Obsidian bladelet fragments were collected in the 1988 field season with Trent University at the Mayan site of Cabal Pech which is a ceremonial and administrative centre occupied in the Late Preclassic and Late Classic periods. Trace element analysis of these samples resulted in provenience information relating to known obsidian sources for the Central American region, and a relative chronological placement of architectural phases at the site by means of hydration rim dating. The C-14 dating of lirnestone plaster samples from the site was also attempted but with limited success. These resulting dates were far too early to be possible due to the dilution effect of geological carbonates, however the dates were appropriate for a relative chronology and in agreement with the obsidian hydration dates.},
