摘要
简要叙述陕西省小西沟地区金矿的地质特征,从断裂构造、岩性、矿化富集、热液活动、化探异常、围岩蚀变等几个方面论述它的成矿规律,认为该区的金矿富集与钾长石脉有很大关系,断裂构造以及其次级构造内的脉岩直接赋存金矿体;钾长石脉、石英脉等是找矿的直接标志。
The geological characteristics of gold deposits in Xiaoxigou area were briefly narrated. The metallogenic regularity of the deposits was discussed by analyzing the fracture structure, lithology, mineralization enrichment, hydrothermal activity,geochemical anomalies and wall rock alteration. The enrichment of gold had great relationship with potassium feldspar veins,fracture structure and its sencondary structure in the ground. Potassium feldspar veins and quartz veins were the direct sign of prospecting.
