In this study on speaking about minerals, we can use the elements from them in high-tech technology in everyday life. The pegmatites are surrounded by gneiss with muscovite, garnets, staurolite; mica schists with garnets, staurolite, kyanite; and amphibolites. In the Con?u area pegmatites appear in tabular veins form, or irregular lenses, arranged by accordance with mica schists of the host metamorphic rocks. The pegmatites veins have a thickness that varies between 2 and 10 meters in the central area and development in the direction between 170 and 475 meters. Viewed from the point of mineralogical composition, pegmatites can be divided into two types: muscovite ?feldspathic pegmatites and Li-bearing pegmatites characterized by the association of albite ? spodumene. In Con?u pegmatites we have mains minerals like spodumene, quartz, albite (cleavelandite variety), and muscovite. Minerals accessories are indicated by "Quensel ? Manson" sequence triphylite ? ferrisicklerite - heterosite, amblygonite - montebrasite, fluorapatite, hydroxylapatite, wolfeite, maricite, monazite, "ferrogatehouseite", beryl, uraninite, sillimanite, microcline, microcline - perthite, oligoclase, biotite, columbite, tantalite, titanite, tourmaline (schorl variety), cassiterite, garnets (almandine and spessartine variety). The analytical methods of analysis are indicated by Polarized Light Microscopy (PLM), X-Ray Powder Diffraction (XRD), Infrared Spectroscopy (IRS), Electron Probe Micro-Analyzer (EPMA), Raman Spectroscopy (RS), Scanning Electron Microscopy (SEM).
