| 摘 要： | 根据20世纪60年代全国范围内展开的自然重砂测量工作所累积的自然重砂数据资料,统计了全国各省72个典型银矿床的自然重砂情况,通过计算和分析各自然重砂矿物在所对应的类型的矿床中的报出频率,得出火山沉积型、沉积型、变质型、侵入岩型4种类型的银矿所对应的自然重砂矿物组合。展现这4种类型矿床的重砂矿物组合的相似之处及不同之处。按照这种方式建立的不同矿床类型的自然重砂矿物组合,对于建立自然重砂找矿模型具有重要的意义。

| Abstract: | Based on the data of natural heavy minerals accumulated by the nationwide work of measuring the natural heavy minerals in the 1960s, the authors made a statistic analysis of the occurrence situation of 72 typical silver deposits (mining areas), calculated the frequency of occurrence of many kinds of natural heavy minerals and summed up the mineral assemblages of sedimentary volcanogenic silver deposits, sedimentary silver deposits, metamorphic silver deposits and intrusion silver deposits. The results show that there exist some similarities and differences in mineral assemblages of these four types of silver deposits. The natural placer mineral assemblages based on different types of deposits have significance for building the ore-prospecting model of natural heavy minerals. |
