【摘要】 甘孜—理塘断裂带自古生代以来经历了一系列复杂的演化过程,为一规模宏大、结构复杂并受到新生代喜马拉雅期逆冲推覆和左行平移走滑剪切作用强烈改造肢解的蛇绿混杂岩带。金矿成矿主要与新生代喜马拉雅期逆冲推覆和平移走滑以及成矿期后的表生氧化作用有关。沿该断裂带广泛发育水热活动,显示了现代热液成矿作用仍在进行中。重视新生代喜马拉雅期构造活动规律的研究对该区找矿具有重要意义。更多还原

【Abstract】 The Garzê-Litang fault belt has experienced a series of complex evolutionary processes since the Paleozoic and is a large-scale, structurally complex ophiolitic mélange belt that has been strongly reworked and dismembered by overthrusting and sinistral strike-slip shear during the Cenozoic Himalayan orogeny. Gold mineralization is mainly associated with overthrusting, strike-slip motion of the fault belt and post-mineralization supergene oxidationn during the Himalayan orogeny. Hydrothermal activity is widely developed along the fault belt, showing that modern hydrothermal mineralization is just taking place. The study of the regularity of the Himalayan tectonic movement is of great significance for mineral prospecting in the study area.更多还原
