Geochemistry and petrography of skarn mineralization associated with Syrostan massive, Miass region (Southern Ural); [ГЕОХИМИЯ И ПЕТРОГРАФИЯ СКАРНОВОГО ОРУДЕНЕНИЯ, СВЯЗАННОГО С МАССИВОМ СЫРОСТАН, МИАССКИЙ РЕГИОН (ЮЖНЫЙ УРАЛ)]

A considerable type of deposits, including those for W, Sn, Mo, and Cu, are found in the skarn. Skarn mineralization can be found southwest of Miass City, near the boundary between marble deposits and diorite in massive complex. We describe the Skarn’s petrography and geochemistry in this research. For our geochemical analysis with ICP-MS, EMPA, and X-ray spectral fluorescence analysis and petrography study, we collected samples of both the skarn and igneous rocks in the Syrostan massive. Petrography study revealed that garnet, epidote, amphibole, and pyroxene dominate skarn mineralization. Garnet and pyroxene minerals represent early metasomatic stage, indicating a prograde stage of alteration. Retrograde alteration, is distinguished by the presence of epidote, quartz, calcite, and chlorite. The skarn is associated with Syrostan massive, which dominant by metaluminous I-type granite and high-K calc-alkaline series granitic rocks. In comparison to igneous rocks granite and diorite, the skarn sample showed high enrichment in HREE. Skarn samples appeared to have higher concentrations of Mo, W, Sn, Ta, and Nb than igneous rocks form the Syrostan massive. skarn mineralization containing iron oxides, the Co/Ni ratios in the iron oxide (2.5 to 5.5) describe how the hydrothermal process affects the magmatic source. Based on these findings, we propose that W, Sn, and iron oxide mineralization may occur in skarn. © 2024 Publishing house Mining book. All rights reserved.
