| Abstract | ||||
| Gala En Nahal area constitute late Precambrian Alpine-type mafic-ultramafic rocks, considered as ophiolites masses. These ophiolite masses are deformed, sheared and dismembered. They consist of serpentinized chromitiferous ultrabasic rocks, metagabbro, diorite and dykes of various composition. Later talc magnesite schist and biribrite are formed as an alteration product of the mafic ultra-mafic rocks. Industrial minerals such as chromite, talc, asbestos and magnesite have been reported. Samples are taken from biribrite rock and subjected to (XRF) and (AAS) analysis. The results of analysis show sigificant values for Au, PGE, Ni, Co and Ag Analysis of Talc-carbonate rocks also show ore minerals of Ni-Co arsenide, pyrite, and chalcopyrite silica-carbonate stock works are surface criteria for mineralization. | ||||
