| 摘 要： | 依据区域地质构造演化、岩石组合及同位素测年资料, 将吉林省晚三叠世-早白垩世花岗岩划分为裂解型、走滑型和会聚型3类成因构造类型。其中, 裂解型岩套与铜镍、磷、钒钛磁铁矿相关; 走滑型岩套与贵金属、多金属矿相关; 会聚型陆内板片(A型) 俯冲亚型花岗岩套与斑岩型钼矿、金矿及铜矿等相关。早侏罗世岩浆作用形成的矿床以钼矿为主, 晚侏罗世-早白垩世转向金、铜、铅锌矿为优势。成因构造类型岩浆岩套呈节律式地更新递进, 反映出太平洋板块与东北亚滨太平洋大陆边缘互动的复杂性, 及岩浆演化活动的规律和动态过程。

| Abstract: | Late Triassic—Early Cretaceous granites in Jilin Province can be divided into three types tectonically originately, including cracking, strick-slip and convergent types, according to the regional tectonic evolution, rock assemblage and isotopic dating data. The cracking type suite is related to Cu, Ni, P, V and Timagnetite, the strick-slip type suite is related to the noble metallic and pollymetallic deposits, and subduction subtype granite suite of convergent type intra-plate sheet (A type) is related to the porphyry Mo, Au and Cu deposits. The deposits formed by Early Jurrasic magmatism are mainly Mo, and turned to Au, Cu and Pb-Zn deposits in Late Jurassic—Early Cretaceous. The regular update and progress of cause structure type magmatic suite reflect the interactive comp lexity between the Pacific Plate and the Northeast Asian continental margin of peri-Pacific Plate, and the evolutinary regulartion of the magmatism. |
