Lithium-cesium-tantalum (LCT) pegmatites are highly evolved granitic pegmatites enriched in lithium, cesium, tantalum, and other rare elements. They can host economically important minerals such as spodumene and may also contain tantalum-, tin-, and cesium-bearing minerals. Their coarse mineralogy and variable internal zoning strongly influence exploration, resource evaluation, and mineral processing.
The following Elements and Minerals may be found in this Deposit Type.
Mineral: Spodumene - LiAlSi₂O₆ - Spodumene is one of the principal lithium ore minerals in lithium-cesium-tantalum (LCT) pegmatites.
