New Mexico Mineral Symposium — Abstracts

The Hansonburg Mining District, located near Bingham, New Mexico, is host to a large number of minutely-crystallized, late stage oxidation minerals. Because of the rarity of some of these species, many misidentifications have been made by investigators who rely on sight identification. A review of rare minerals verified from this locality by X-ray diffraction, X-ray fluorescence, scanning electron microscopy with energy dispersive X-ray analysis, and optical mineralogy is presented with a brief discussion of species erroneously reported from the area.

In addition to the review, recently gathered data will be presented chat verifies tsumebite from the Hansonburg district. This is the first reported occurrence of this mineral in New Mexico.
