The selection of two mineragenesis epochs of granitoides complexes is confirmed. Metallic (spodumene pegmatites) and non-metal (rough gems: epidosite, rose quartz, graphic granites, petalite) minerals are in granitoides with titanic specialization. Metallic (rare earths and uranium) and non-metal (pegmatites, tourmaline, sodalite) minerals are in granitoides with aluminium specialization. Presently non-metal minerals have a considerable economic attractiveness. Scientific bases of rough gem quality estimation are developed and the algorithm of estimation of gemmological objects is offered.
These results were inculcated in practice of geological survey works and used for the wide list of tasks that are actual for many modern geological researches.
