摘要
金矿体赋存于澜沧群惠民组上段中下部F2断层破碎带中,构造角砾岩、碎裂岩、碎斑岩是主要含金岩类。氧化矿石,金包裹于褐铁矿及绢云母中、少量自然金,属中低温破碎带蚀变岩型金矿。
The Au orebody is in the F2 fault fracture zone in middle-lower part of Lancang Group Huimin For- mation Upper Member. The main Au-bearing rocks are structural breccia, cataclastic rock, porphyroclastic rock. The oxide ore, Au inclusion in limonite and sericite, a few natural Au, belonging to middle-low T fracture zone Au deposit of alteration rock type.
