这里所提出的分类是根据地质构造环境、围岩性质和矿物共生组合,因此,这种分类具有成因内容,并且力图突出金的稳定性.主要可分为三大类:1.造山前的火山—沉积建造矿床,2.造山后的深成—火山建造矿床3.碎屑建造矿床近三十年来,对矿床成因方面最主要的修正是将台黄铁矿和多金属硫化物团块解释成火山—沉积同生矿床.以加拿大太古代矿床为例,我们惊奇地发现在优地槽的不同层位里出现金矿床和多金属硫化物矿床,而金
The classification proposed here is based on the geological tectonic setting, the nature of the surrounding rock and the symbiosis of minerals, so this classification has genetic causes and attempts to highlight the stability of the gold. There are three major categories: 1. Pre-orogenic volcanoes - Sedimentary deposits 2. Deep orogenic volcanic deposits 3. Post-orogenic detritus 3. Detrital ore deposits The most important revision to the genesis of the deposit over the last three decades was the interpretation of the pyrites and polymetallic sulphides Volcano-sedimentary symbiotic deposits. Taking the Archean Archean deposits of Canada as an example, we were surprised to find that gold deposits and polymetallic sulphide deposits are present in different layers of the Eudemonium,
