Description

Occurrence

Kulanite is known from Austria, Canada, China, the Czech Republic, and the United States.^[1]

History

Alan Kulan and Gunar Penikis, residents of Ross River, Yukon, collected a number of mineral specimens from the Rapid Creek area in 1974. They sent these to the Royal Ontario Museum's Department of Geology, and among them was discovered a new mineral. The mineral was named kulanite in honor of Kulan; the IMA Commission on New Minerals and Mineral Names approved the mineral and its name.^[3]

The type material is held at the Royal Ontario Museum in Toronto and the National Museum of Natural History in Washington, D.C.^[2]
