noun
1
a translucent, typically grayish-white aluminosilicate mineral that is an important source of lithium.
The dike is characterized by a greater abundance of muscovite than biotite; it also contains columbite-tantalite, cassiterite, beryl, spodumene , lepidolite, montebrasite, pollucite, and tourmaline.

1. Titanian ferrocolumbite is a rare accessory mineral in the spodumene-bearing pegmatites at Weinebene, Carinthia, Austria.

2. Augite, diopside, jadeite and spodumene are four of the best-known members of the pyroxene group; however, the pyroxene group has many other members

3. Lepidolite and lithian muscovite occur in high-pressure spodumene, low-pressure petalite, phosphorus-enriched amblygonite and fluorine-rich lepidolite subtypes of orogenic affiliated complex type granitic pegmatites and rarely in anorogenic affiliated amazonite-bearing Trace element data determined by X-ray fluorescence for lepidolite of various pegmatite subtypes, morphology (“book”, “scaly”, “fine-grained”), position within the pegmatite (primary zones, replacement units, pockets), mineral assemblages and tectonic affinity (orogenic vs anorogenic) show extreme fractionation of Rb and Cs; modest levels of T1, Ga, Nb, Ta, Sn and Zn; and typically low abundances of Ba, Sr, Ni, Pb, Y, V, W and Zr.
