The ancient Maya often made these heavy, bulky tools of coarse-grained, heterogeneous materials that are difficult to chemically source, unlike obsidian. This paper describes an application of handheld, energy-dispersive X-ray fluorescence (XRF) to provenance ground stone artifacts (tools and architectural blocks) composed of granite: a nonhomogenous, phaneritic stone. We present a multicomponent methodology that independently tested whole-rock, thin-sectioned, and powdered samples by petrographic microscope, conventional, lab-based XRF, and portable XRF units,
