摘要
该岩金成矿带控矿构造为位于金木达—南木达断裂带强应变中心部位的控岩控矿韧脆性叠加剪切断裂带,赋矿地层为上三叠统新都桥组,属深海浊积扇的外扇—盆地平原相沉积。该带侵入岩发育,成矿环境优越,具较好的找矿潜力。分析该带金矿的成矿条件及富集规律具有重要的意义。
The Shangduhe-Namda Au metallogenic zone is confined to the Upper Triassic Xinduqiao Formation belonging to turbidity fan-basin plain sedimentary facies. The Au deposits are controlled by the Jinmuda-Namda fracture zone. Intrusions are well developed in the zone. These are of importance to Au prospecting.
