Cesplumtantite - Occurrence, Properties, and Distribution

Cesplumtantite is a tetragonal, colorless mineral, containing tin, tantalum, sodium, oxygen, niobium, lead, cesium, calcium, and antimony.

The mineral was first discovered in 1986 from Manono in Shaba, Zaire. It was named after the presence of tantalum, plumium (lead), and cesium in its composition.

How to Identify Cesplumtantite

Cesplumtantite is a colorless, transparent mineral, with white streak, and adamantine luster.

It can be formed as microscopic crystals, and its hardness is 7.

Global Distribution

Cesplumtantite is widely distributed in Manono pegmatite, Katanga Province, Congo.

Occurrence of Cesplumtantite and Useful Mineral Association

Cesplumtantite occurs in veinlets in a museum specimen from a granite pegmatite.

It is closely associated with thoreaulite, microlite, calciotantite, cassiterite, and lithiotantite.
