Named for the type locality in St. Peters Dome in the Cheyenne district of El Paso (Elpaso) County in Colorado, USA. Elpasolite is a rare mineral that can be found in additional USA localities as well as in Italy, Greenland, Ukraine, Russia, and the Democratic Republic of the Congo. Elpasoite occurs as a replacement for fluorine minerals in quartz-microcline pegmatites and in quartz veins associated with hydrothermal antimony deposits in silicon rich limestone.

Named for John Ely, a promoter of an early mining company from Nevada, USA and frontiersman. Elyite is an uncommon mineral that forms in oxidized portions of base metal sulfides as well as in dumps and slags. It can be found in localities in the United States, Germany, Japan, Namibia, England, Scotland, Wales, and others.

Named in honor of Peter Godwin Embrey, an English mineralogist for the British Museum of Natural History in London, England. Embreyite is a rare mineral that occurs in Russia at the Berezovskoe gold deposit in the Urals region, in the Argent mine in South Africa, at the Callenberg North No.1 open cut in Saxony, Germany, and in the Le Cantonnier vein in Aquitaine, France. At its Russian locality it occurs on museum samples from the oxidized gold-bearing quartz veins. Associated minerals include crocoites, phoenicochroite, vauquelinite, cassedanneite, cerussite, fornacite, pyromorphite, and mimetite.
