浅析大渡河金成矿带中的剪切构造及其意义

Shear structure in the Dadu River gold metallogenic belt and its significance

通过对大渡河金成矿带控矿构造的研究发现,成矿带中矿床和矿体均受不同级别的剪切构造的控。区域性韧性剪切带控制了成矿带的展布;其次级构造密集带为矿田边界;剪切破碎带、层间破碎带、裂隙带直接控制矿床和矿体。

Through the study of ore-controlling structures in Daduhe gold metallogenic belt, it is found that ore deposits and orebodies in the metallogenic belt are controlled by shear structures of different grades. The regional ductile shear zone controls the distribution of the metallogenic belt, the secondary structural dense zone is the boundary of the ore field, and the shear fracture zone, interlayer fracture zone and fracture zone directly control the deposit and orebody.
