里伍矿田构造特征及控矿规律

Structural Characteristics and Ore Controlling Law of Liwu Orefield

里伍矿田位于松潘-甘孜造山带的南缘,康滇地轴北段西部。本文对该穹隆的区域地质背景、构造地质特征、及穹隆构造变形与成矿关系进行了分析。综合分析认为,从矿田构造角度探讨了该区铜矿成矿地质条件。通过对矿田内主要的构造特征进行总结,认为区内该穹隆成矿作用受面理、褶皱、断裂等构造作用的影响,矿体主要受穹隆体多层次韧性剪切滑脱带的控制。

The Liwu orefield located in the south edge of Songpan-Ganze orogen and the west of Kangdian Earth'saxis. The paper analysis the dome's regional geological background, structural geology, the relationship between tectonic deformation and mineralization. We hold the view that the dome mineralization affected by the follations, folds, crack, etc. The deposits is controlled by the extensional ductile shear zones. The dome main development Liwu, Heiniu dong, Wa jing gou, etc copper, zinc ore deposits(points).
