摘要
小秦岭地区的断裂构造可划分为:幔型断裂、壳型断裂和区域断裂.幔型和壳型断裂是导矿构造,控制了物化探异常及矿带展布方向,其派生次一级构造控制了物化探异常的高值区及矿体展布方向.本文从不同方向、不同发育规模的断裂构造地球化学特征出发,探讨了断裂构造对金矿的控矿作用.
Among the fracture structures in the Xiaoqinling district, the following types are distinguished: (1) mantle; (2) crustal; (3) regional. The former two types belong to ore-giude structures which contsol the extending direction of geophysical-geochemical anomalies and ore belts. And their derived secondary structures control the geophysical anomaly highs, geochemical anomaly concentration centres and the strike of ore bodies respectively. In this paper proceeded from the geochemical signatures of the fracture structures developed in different directions and scales, their control of gold deposit is discussed.
