Quenselite

Named in honor of Professor Perry Dudgeon Quensel, who was a Swedish mineralogist and petrologist at the University of Stockholm at Stockholm, Sweden. Quenselite is found in just a few reported locations including Sweden, India, and Scotland. Mindat reports another set of localities that include China, Japan, Sweden, and the USA. The one locality that can be agreed upon is the type locality at Långban in Sweden. At the type locality, Quenselite occurs within “a metamorphosed Fe-Mn orebody.”
