Minerals of the Himalayas
· 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.
Mineral Resources And Their Conservation
· Mineral Resources And Their Conservation. This article explains about mineral resources of India. Minerals like iron ore, mica, copper, gypsum, bauxite, lead, etc are the nonrenewable and exhaustible resources. Minerals in certain areas are on the verge of extinction and hence it is necessary to conserve them.

Ore is like choc chip biscuits where the minerals are spread through the rocks. The only way to find out how many choc chips there are is to crush the biscuit. In the same way we can sometimes see mineral crystals from the outside of the rock, but mostly we don't know what minerals there are and and what concentrations are inside the rock.
