内蒙古乌拉山金矿构造特征浅析

以构造层次的观点剖析了乌拉山塑性变形构造，韧性剪切带和脆性断裂构造的特征及其演化，认为东西向浅层次的脆性断裂－山前大断裂是乌拉山金矿的导矿构造，其后期（加里东－海西）活动派生的近东西向呈右行雁列的一组剪切断裂是容矿构造，并认为容矿断裂是经历了先压后张２个阶段的脆性断裂。

PRIMARY STUDY ON STRUCTURAL FEATURE OF WULASHAN GOLD DEPOSIT, NEI MONGOL

By analysing the features and the evolutions of Wulashan plastic deformation structure, ductile shear zone and brittle fault structure in accordance with the viewpoint of tectonic level, the EW shallow level brittle faultpiedmont major fault is considered the structure as passageway for ore fluid, the host structure is a group of righthanded en echelon shear faults approaching EW trend, which were derived from the late(Caledonian-Hercynian) activity and is considered the ductile fault which has gone through two stages including the early compression and the late tension.
