Identification the tectonic setting of granite using geochemistry and trace elements: implication for the granites in the Syrostan massive (Southern Ural)

Abstract

Relevance and the purpose of the work. Te use of trace element to diferentiate granite types and tectonic setting is a well-established method in geology and mineral exploration. Te aim of the paper is to determine the tectonic environment of the granite in the Syrostan massive using trace elements and geochemistry which lead to signifcant outcome and revealed of related deposits. Methods of research. X-ray spectral fuorescence analysis was used to determine the concentrations of petrogenic oxides and trace elements in the samples, while trace element and rare earth element (REE) contents were measured using (ICP-MS). Results of the work. Sericite and muscovite are discovered afer plagioclase. Plagioclase exhibits sericitization and epidotization as a result of hydrothermal activity. Accessory minerals (zircon and apatite), include opaque minerals are distinguished. Te trace element geochemistry of intrusion is refected in the YbN vs. (La/Yb)N ratio, which is typical of magmas found in island arcs. Granite and granodiorite formation is a segment of the island arc formed as a result of the post-subduction or syn-collision tectonic setting. indicating that the intrusion associated with the Dark Kingdom Marble deposit can be considered a part of the Syrostan massive with the same general characteristics. Conclusion. Tese fndings imply that the granite formed in a volcanic arc tectonic environment. Finally, these results present the characteristics and tectonic environment of granitic rocks, which can provide valuable insight into related mineralization and rare element concentration.
