Based on geological field investigation, through the study of the following three aspects: (1) petrology and geochemistry of Mesozoic volcanic rock; (2) fluid inclusion features and geochemistry; the chronology of volcanic rock and the gold mineralization, we figured out the initially volcanic genesis, forming age and the gold ore material origin, the fluid origin and the mineralization epoch of the Dong'an gold deposit in Xiaoxing'anling area, and then gave a reasonable explanation on its genesis and geodynamics background of ore forming. The intermediate-acid volcanic rock of the Ningyuancun Formation within study area is a peraluminous K-rich calc-alkaline and calc-alkaline series, which forms from the metasomatosis between differential enriched-mantle magma and continental crust.
本论文在比较详细的野外地质调查的基础上,通过对小兴安岭地区东安金矿区的中生代火山岩的岩石学和地球化学、流体包裹体地质学和地球化学和火山岩与金矿成矿年代学三个方面的研究,初步认定了东安金矿区的火山岩成因和形成时代与金矿的物质来源、流体来源和成矿时代,研究了东安金矿成矿机理,探讨了其形成的地球动力学背景。
