金银的地球化学与成矿学

本文列出各种主要类型岩石和陨石中金、银及与之共生的主要元素之平均含量（最具代表性的均衡含量），这些数据是以元素宇宙地球化学为基础，如亲氧性、亲硅铝性、离心性、亲石性、亲硫性、亲铁性和地壳中标准含量等性质为基础。指出矿床或成矿省中贵金属元素及与之相伴的金属元素分布的相关性，这一关系主要取决于元素的地球化学性质和成矿条件。按元素的铁镁性、硅铝性及成矿作用的不同相条件划分出不同类型矿石中上述元素的标型性关系特点，提出了金、银矿床的地球化学分带性、构造的一般规律性，对于找矿和预测具有重要意义。

COMPARATIVE GEOCHEMISTRY AND METALLOGENESIS OF GOLD AND SILVER

The average contains of gold and silver and main associated elements, which are con-tained in main types of rocks and meteorites are listed in this papers.The datum are based on the element cosmogeochemistry. including oxyphile, sialiphile, centrifugal, siderophile, sulphophile, ferrophile and the standard contents in Earth crust etc. The author have indecated the correlation distribution between the precious metallic elements and associated metallic elements, which are abundant in ore deposits and metalloginic province, this correlation depends on the geochemistry nature and metallogenic conditions.In the light of different facies condition of ferromagnesian, Sialic and metallogenic action, this paper has the standard correlation of the above mentioned elements belonging to different Ore deposits and has presented the geochemistry zoning of gold and silver deposits and the tectonic regularity.It is an important significance to prospect of prognosticate ore deposits.
