Abstract

The present paper considers petrographic and geochemical features of rocks of the Tigrinoe and Zabytoe stocks, provides their mineral composition, the results of the detailed study of micas and mineral-forming inclusions in quartz. It is shown that the development of ore-magmatic systems (OMSs) of the Zabytoe and Tigrinoe deposits is associated with the same rare-metal Li–F melts. It is confirmed that granitoids of the Tigrinoe stock can be considered as more differentiated analogs of granitoids of the Zabytoe stock. New data concerning the differences in the history of the magmatic stage of development of the OMSs of these deposits are presented. The evolution of melts of both deposits took place at high fluid pressure. Differences in the scale of ore mineralization of the two RMSs under consideration could be due to different fluid regime of magmatic sources evolution and more significant participation of transmagmatic fluid flows in the development of the Tigrinoe OMS.

Tigrinoe 和 Zabytoe Sn-W 矿床矿石-岩浆系统来源中稀有金属 Li-F 花岗岩熔体的演化（滨海边疆区锡霍特-阿林中部）

摘要

本文考虑了 Tigrinoe 和 Zabytoe 种群岩石的岩相和地球化学特征，提供了它们的矿物成分、云母和石英中成矿包裹体的详细研究结果。结果表明，Zabytoe 和 Tigrinoe 矿床的矿石岩浆系统（OMS）的发展与相同的稀有金属 Li-F 熔体有关。经证实，Tigrinoe 群花岗岩可被视为 Zabytoe 群花岗岩的更具差异化的类似物。提出了有关这些矿床 OMS 岩浆发育阶段历史差异的新数据。两种沉积物的熔体演化都是在高流体压力下发生的。所考虑的两个 RMS 矿石成矿规模的差异可能是由于岩浆源演化的不同流体状态以及跨岩浆流体流在 Tigrinoe OMS 的发展中更重要的参与所致。
