我们在江西南城砂金矿研究过程中,发现河床剖面有独特的地质条件,即地层的“锈板-碳板”构造。笔者就这种现象,对本区砂金矿的地球化学,进行初步探讨。 1.矿床地质概况:南城砂金矿位于赣杭构造带北部,小构造非常发育。河流两岸的山脉,有数十条北东向断裂,被石英脉所充填。人工重砂大样分析证明,有些石英脉含
During the study of Nancheng placer gold deposit in Jiangxi Province, we found that the riverbed profile has unique geological conditions, that is, the “rust plate - carbon plate” structure of the formation. The author of this phenomenon, the area of gold and gold geochemistry, to conduct a preliminary discussion. 1.Geological overview of deposits: Nancheng sand gold deposit is located in the northern part of Gan-Hang tectonic belt with a very small structure. There are dozens of NE-trending faults in the mountains on both sides of the river and are filled with quartz veins. Heavy artificial sand large sample analysis shows that some quartz veins
