Trace element analysis of obsidian artifacts from Moho Cay, Belize, reveals that the obsidian derives primarily from the El Chayal outcrop in highland Guatemala and not from the Ixtepeque source. This is contrary to the widely accepted obsidian trade route model for Classic Maya civilization and suggests that Classic Maya obsidian trade was a more complex economic phenomenon than has been recognized.
对来自伯利兹莫霍凯的黑曜石制品的微量元素分析表明,这些黑曜石主要来自危地马拉高地的埃尔恰亚尔露头,而不是伊克斯泰佩克来源。这与广泛接受的古典玛雅文明黑曜石贸易路线模型相反,表明古典玛雅黑曜石贸易是一种比人们认识到的更为复杂的经济现象。
