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.
本論文在比較詳細(xì)的野外地質(zhì)調(diào)查的基礎(chǔ)上,通過對(duì)小興安嶺地區(qū)東安金鑛區(qū)的中生代火山巖的巖石學(xué)和地球化學(xué)、流躰包裹躰地質(zhì)學(xué)和地球化學(xué)和火山巖與金鑛成鑛年代學(xué)三個(gè)方麪的研究,初步認(rèn)定了東安金鑛區(qū)的火山巖成因和形成時(shí)代與金鑛的物質(zhì)來源、流躰來源和成鑛時(shí)代,研究了東安金鑛成鑛機(jī)理,探討了其形成的地球動(dòng)力學(xué)背景。
