摘要：

作者通过对依兰-舒兰地区中生代花岗岩构造环境分析和其它构造背景等资料的综合研究,认为依舒断裂带在中生代经历了大陆弧内走滑断裂(T-J32)、造山后期地堑雏形(J33-K11)、被动大陆裂谷(K12-K2)和萎缩(K3)等四个演化阶段。

Abstract:

Yisu(Yilan-Sulan)fault zone is a branch in the north section of the famouse Tancheng-Lujiang fault zone in East China.In application of Maniar's granitoid discrimi-nation,Mesozoic granitoids distributed in Yilan-Sulan area could be classified into follow-ing types:1.continental-arc granitoids(CAG)of Triassic-middle Middle Jurassic;2.post-orogenic granitoids (POG) from late Late Jurassic to early Early Cretaceous;3.the CAG and POG granitoids of Late Jurassic.The tectonic environment of the granitoids and the plate tectonic settings of the whole Northeast China in Mesozoic were coordinated and could be divided into four evolution stages:1.intra-continental arc strike-slip faulting(T-J32);2.post-orogenic rudimento-graben (J33-K11);3.passive rift (K12-K2) and 4.rift contraction (K3).
