摘要
本区位于滇西特提斯沟—弧—盆构造体系的主火山弧地体中,处于澜沧江褶断束东凸弧形转折处,上三叠统小定西组钙碱性火山碎屑岩、次火山岩含矿,火山机构控制矿体的产出形态,后期构造、侵入体使矿体叠加、富积,矿化类型为火山—次火山岩热液改造矿床;地、物、化、遥等成矿地质条件有利,具有很好的找矿前景。
This area is in the Tethys main volcanic arc terrain of trough-arc-basin structural system,the E convex arcuate turn of Lancangjiang fold-fault bundle.The occurrence form of ore body is controlled by Upper Triassic Xiaodingxi Formation calc-alkali volcanic clastic rock,subvolcanic rock and volcanic mechanism,the superimposition and concentration of ore body are caused by posterior structure and intrusion.The metallogenetic type belongs to the volcanic—subvolcanic hydrothermal reformation deposit.The metallogenetic conditions of geological,geophysical,geochemical and remote sensing information are advantageous,with good ore prospecting potentiality.
