Kulanite (pronounced KU LĂ·N AIT)[3] is a mineral with formula

Description edit

Occurrence edit

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

History edit

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]
