从岩浆活动的空间分布及演化特征的角度,研究了岩浆活动与金矿成矿、地球动力学之间的内在联系。提出了金矿成岩成矿具有统一性和周期性的6阶段演化的动力学模式。即T1-T2,羌塘地体、冈底斯地体雏形阶段;T3-J1,班怒洋盆、雅江洋盆雏形阶段;J2-J13洋盆不断扩张形成蛇绿岩套及与其有关金矿床阶段;J23-K1、洋盆闭合、地体拼合、雅江洋盆北向俯冲,形成变质热液型金矿床或与花岗岩有关的Au(Cu)、Sn、Pb、Zn成矿系列;K2-E2雅江蛇绿岩侵位阶段;E2以来,地幔柱形成高原隆升,砂金矿形成阶段。
From the perspective of the spatial distribution and evolution characteristics of magmatism, the intrinsic relationship between magmatism and gold mineralization and geodynamics is studied. A unified and periodic 6-stage kinetic model of gold mineralization has been proposed. Namely, T1-T2, Qiangtang terrane, prototype of Gangdese terrane; T3-J1, Banteng ocean basin and the Yawang oceanic basin; J2-J13 oceanic basin expanding to form ophiolite suite and related gold deposits Stage; J23-K1, ocean basin closure, terrane merge, north subduction of the Yangjiang basin to form metamorphic hydrothermal gold deposits or Au (Cu), Sn, Pb and Zn mineralization series related to granite; K2-E2 Yajiang Ophiolite emplacement stage; E2 since mantle plume formed plateau uplift, gold and gold formation stage.
