Geological map of Nepal. The Himalayan mountains are not rich in economically valuable precious minerals. However, trapped within the earthly confines of pegmatites, marbles, and gneisses are minerals of low economic value. These minerals include: Garnets, kupfferite, tourmaline, spinels, chrysolite, euclase, kyanite, corundum, ruby, beryl, muscovite, jade, jasper and many others.

The color is usually caused by an elevated content of Pb (up to 1.2% PbO, see list of references).
Tanzanite is the blue and violet variety of the mineral zoisite (a calcium aluminium hydroxyl sorosilicate), caused by small amounts of vanadium. Tanzanite belongs to the epidote mineral group. Tanzanite is only found in Tanzania, in a very small mining area (approximately 7 km (4.3 mi) long and 2 km (1.2 mi) wide) near the Mererani Hills.
Small amounts of salt and phosphate are mined from Barbuda and Redonda, respectively. But the main quarrying activity that takes place in Antigua and Barbuda is sand mining on the island of Barbuda. Sand mining has historically been the largest industry on the island, despite its potentially devastating side effects.
Fluorapatite, often with the alternate spelling of fluoroapatite, is a phosphate mineral with the formula Ca 5 (PO 4) 3 F (calcium fluorophosphate). Fluorapatite is a hard crystalline solid. Although samples can have various color (green, brown, blue, yellow, violet, or colorless), the pure mineral is colorless, as expected for a material lacking transition metals.
Larimar is a type of pectolite or a rock composed largely of pectolite, an acid silicate hydrate of calcium and sodium.
