- Abstract
The discovery of jadeitites in Guatemala in 1954 led to the recognition of the Motagua River Valley as a Maya jade source. Matching artifacts with jadeitite sources has been a problematic endeavor. Chemical composition has been used for sourcing many lothic materials, but jadeities are inherently inhomogeneous which precludes matching by whole-rock chemical analysis. Minor mineral constituents are better than whole-rock composition for sourcing, because they do not get lost in the noise of whole-rock analysis. Minor paragonite or barium-rich muscovite mica and titanide are the fingerprint for most Guatemalan jadeitite and Mesoamerican jades.
