Fluorescent minerals in pegmatites

WebJun 20, 2024 · Lithium-cesium-tantalum (LCT) pegmatites comprise a compositionally defined subset of granitic pegmatites. The major minerals are quartz, potassium feldspar, albite, and muscovite; typical accessory minerals include biotite, garnet, tourmaline, and apatite. The principal lithium ore minerals are spodumene, petalite, and lepidolite; … WebMinerals are composed of atoms, which in turn contain electrons at specific energy levels. Ultraviolet light is an energy source. When we shine an ultraviolet lamp on a mineral that fluoresces, the atoms that make up the mineral absorb energy from the light by moving electrons to higher energy levels.
