本文对自然金银矿物的Au、Ag含量的标型意义做了比较全面的论述。自然金银矿物Au、Ag含量的标型意义主要由以下三方面来反映:(1)矿床中自然金银矿物的组合特点;(2)自然金银矿物内部Au、Ag含量的均匀性;(3)自然金银矿物的成色。对以上三方面所反映的矿床成因、矿床形成条件、形成时代及矿床类型等的意义分别作了探讨。对于指导矿床深部的评价及寻找矿金的源区等有实用意义。
This article made a more comprehensive exposition on the standard meaning of Au, Ag content of natural gold and silver minerals. The standard significance of natural gold and silver minerals Au and Ag is mainly reflected in the following three aspects: (1) the combination of natural gold and silver minerals in the deposit; (2) the uniformity of Au and Ag contents in natural gold and silver minerals; ( 3) natural gold and silver mineral fineness. The above three aspects reflect the genesis of the deposit, the forming conditions of the deposit, the forming age and the significance of the type of deposit. It has practical significance for guiding the deep evaluation of the deposit and searching for the source area of the gold deposit.
