类复理石地层中“脉——细脉型和细脉——浸染型”金矿床属于浅成矿床,它们的一般标志是围岩交代改造的体积相当大;矿体的构造随深度的变化不明显;控矿构造除断层外,还有褶皱,以及围岩的岩性特征、矿石物质成份比较简单,金分布均匀.由于石英含量饱和程度及构造——岩石环境的差异,形成的矿石主要为浸染型、细脉浸染型或网脉型.矿床按构造——形态标志和矿物特性可划分为两类:第一类矿床为细脉—脉金—石英矿石的“脉状—网脉型”矿床,具如下特点:
The “vein-fine vein type and veinlet-disseminated type” gold deposits in the class of complex flysch formations belong to the shallow ore-forming beds. The general sign of them is that the volume of the replacement and remolding of the surrounding rock is quite large; the structure of the ore body changes with depth Which is not obvious. In addition to the faults, the ore-controlling structure has folds and lithologic characteristics of the surrounding rocks. The composition of the ore materials is relatively simple and the gold is evenly distributed. Due to the degree of saturation of the quartz content and the difference of the tectonic-lithic environment, Disseminated, vein-disseminated or reticulated type.The deposit can be divided into two types according to tectonic-morphological characteristics and mineralogical characteristics: the first type is vein-vein-vein type "Deposits, with the following characteristics:
