广西镇龙山金(银)矿的构造控制特征

The feature of tectonic control of Zhen-Long-Shan Gold (Silver) Deposit, Guangxi

本文阐述了广西镇龙山金(银)矿化集中区内主要断裂构造的基本特征,并指出,其中规模较大的、与矿化关系较密切的主要是近EW向,次为近SN向断裂,它们组合成线状、交叉状和放射状断裂带,并严格控制着区内岩浆岩、矿化带、矿脉、矿体和“富矿包”的空间展布.这对找矿评价和预测盲矿体都具有实际意义.

The basic features of fracture tectonics of Zhen-Long-Shan gold (silver) mineralized area are described in this paper.It points out that the fracture tectonics in larger scale which has close relation to mineralization are principally those ones which run nearly from east to west and secondarily the other ones which run almost from south to north.They are all composed into fracture zones in linear or intersection or radiation shapes which strictly control the spatial distribution of magmatic rocks, minerlized belt, ore vein, orebody and 'rich ore pocket' in the mineralized area. These features of fracture tectonics are of great significance to the evaluation of ore-prospecting and the prognostication of blind orebody.
