江西金山金矿床两类矿化及其石英热发光特征

金山金矿床为一大型剪切带型独立矿床，主要矿化类型分为含金石英脉及硅化岩型两种，前者分布于金山剪切带上盘粉砂质千枚岩中，受顺层剪切裂隙控制，规模较小；后者主要受金山剪切带内Ｒ型剪切裂隙控制，规模大。研究表明，两类矿化是性质相同的含矿变质流体以不同方式在不同构造位置发生成矿作用的产物。石英热发光特征是评价两者含矿性的有效标志。

THE TWO MINERALIZATION TYPES AND THE THERMOL UMINESCENT EVALUATION MARKS OF QUARTZ IN JINSHAN GOLD DEPOSIT, JIANGXI

Jinshan gold deposit is an independent large scale shear zone type. The main mineralization can be classified into two types, which are gold bearing quartz vein type and the silicified rock type respectively. The former one which is controlled by bedding shearing fracture and relatively smaller in scale, is mainly distributed in silty phyllite rocks on the upper of Jinshan shear zone. The later one is of a larger scale and mainly controlled by the R type shearing fracture developed in Jinshan shear zone. The study shows that the two types of mineralization are the results of mineralization by the ore bearing metamorphic fluids of same features. The thermoluminescent characteristics of quartz are important and effective marks in evaluating the gold bearing feature.
