Energy-Dispersive X-Ray Fluorescence analysis of Haleakalā basalt adze quarry materials, Maui, Hawai'i

► We collected lithic materials from a major Hawaiian basalt adze quarry. ► We examined these lithic materials using Energy-Dispersive X-Ray Fluorescence. ► Analysis of Sr and Zr appears sufficient for distinguishing major basalt sources. ► EDXRF appears effective for distinguishing material from major basalt sources.
