    primary mineral, in an igneous rock, any mineral that formed during the original solidification (crystallization) of the rock. (quartz, feldspar, plagioclase, pyroxenes, olivine, micas) secondary minerals form at a later time through processes like weathering and hydrothermal alteration. (clays, salts),gemstone mining techniques — gemstones and sustainable,the mining techniques adopted to extract gemstones invariably reflect the nature of the deposit: primary deposits (in hard rocks, worked underground or in open pits) and secondary deposits (found in sedimentary, soft-rock, placers). the mineralogy of a gem dictates the type of geological environment in which it can be found.
