Compared with deposits genetically related to granites or basalts, the study of pegmatite and its related deposits is very defective. The knowledge of pegmatite as a tracer of orogenic process is needed. In fact, as the granite and basalt can be used as good tracers of tectonic evolution, pegmatite and pegmatitetype deposits can also be used to trace the tectonic history especially the continental orogenic process. The Altay metallogenetic province is one of the most important pegmatite province in the world, with pegmatites formed in Caledonian, Hercynian, IndoSinian and Yanshanian. It shows a clear regularity that the largest pegmatitetype rare metal deposits formed at the last, [WTBX]i.e[WTBZ]. Yanshanian, stage, with a most complex structure of pegmatite vein and most comprehensive mineral and element assemblages. So, even pegmatite can form at different stage of the continental evolution, the most evolved pegmatite and most important pegmatitetype rare metal deposits formed at the relative silent stage of the orogenic process, because meltfluids can only concentrate and contribute to forming a wellzoned pegmatite vein at an even environment, instead of at a tectonically active environment during the peak stage of orogeny. Similar examples can be found at different orogenic belts around the world. Therefore, pegmatite deposits, especially the larger, wellzoned deposits with multielements and complex mineral assemblages usually represent the product of postorogeny.
