From mineralogy to geochemistry (by the example of pyrite from rock complexes of Crimea Mountain)

Integrated mineralogical and geochemical research of pyrites from magmatic and sedimentary complexes of Crimea Mountain is made with microprobe and precision LA-ICP-MS analyses and traditional techniques. The typomorphic and indicating features of pyrites are determined. According to the data of LA-ICP-MS analyses 48 elements of admixtures are established. The values of indicating relations such as Th/Co - La/Sc, Sc - Th/Sc, Co/Ni give the opportunity to conclude that magmatic rocks of basic and average composition are the source of elements in pyrites. The composition of endogenic and sedimentary complexes indicates to the geochemical peculiarities of sulfide mineralization as a specific petrographic and lithogenetic factor.
