Mineralpedia Details for Whiteite-(CaFeMg)
Whiteite-(CaFeMg)
All Whiteite species are named after John S. White Jr., the Associate Curator of Mineralogy in the Department of Mineral Sciences at the Smithsonian Institution in Washington D.C, USA and also founder and former editor of the Mineralogical Record magazine. Whiteite was formerly described as one mineral but has since been split into alternate species depending on the dominant chemical composition of the mineral in question. At only three localities worldwide, Whiteite-(CaFeMg) is found in “complex zoned granite pegmatites” and iron formations.
