Baotite

Baotite

Named for the type locality at the Bayan Obo deposit in the Baotou Prefecture of China. Baotite is a rare mineral that can be found in additional localities in the United States, the Czech Republic, Austria, France, and a few others. It occurs in quartz veins that cut quartzite at the type locality and in a carbonate vein that cuts hornblende gneiss that is intruded by diabase sills and pegmatites at a USA locality.
