Discovery and occurrence

edit

Mohite was first described in 1982 for an occurrence in the Chatkal-Kuramin Mountains of eastern Uzbekistan. It was named after Günter Harald Moh (1929–1993), University of Heidelberg.[3] It is of hydrothermal origin and occurs associated with tetrahedrite, famatinite, kuramite, mawsonite and emplectite in the type locality in Uzbekistan.[2] It has also been reported from Salamanca Province, Spain; the Organullo Mining District of Salta Province, Argentina; and the Delamar Mountains of Lincoln County, Nevada, US.[2][3]
