摘要 本文据随州市北部地区的地质特征,结合稀土元素及元素含量特征、同位素及矿物包体等资料的综合分析,指出了本区金的矿源岩和赋矿岩石;指出岩浆和构造不仅为金银的运移****了热动力,而且****了富钾富硅的高盐度渗流热液;论证本区金银成矿的温压条件介质条件和硫、氧等逸度条件。圈出金银成矿的最佳部位。 According to the geological condition,REE and other elements contents,isotope and mineral inclusion characteristics,the source and hosting rocks for gold ores are identified in this region.Magma and structure provide not only thermodynamic force for gold and silver migration,but also high salinity filtration hydrothermal flow with rich potassium and rich sil- icon.The author has also discussed in the paper the temperature and pressure,media,sulfur and oxygen fugacities for gold and silver ore formation.The optimal areas for gold and silver ore formation are delineated.
