金矿床以具有仅限于某一类金矿床的典型矿物组合(金-黄铁矿-毒砂,金-多金属-硫化物;金-碲化物;金-辉锑矿;金-辰砂)之一为特征。特定的矿物组合主要受沉淀环境的pH值和温度变化的控制。具有前3种矿物组合的金矿床起源于与花岗岩类或岩浆体系有关的流体,具有后2种矿物组合的金矿床起源于壳下非岩浆流体。
The gold deposit is one of the typical mineral assemblages (gold-pyrite-arsenopyrite, gold-polymetallic-sulfide; gold-telluride; gold-stibnite; gold-cinnabar) with only one type of gold deposit For the characteristics. Specific mineral assemblages are mainly controlled by changes in pH and temperature of the precipitation environment. The gold deposits with the first three mineral assemblages originated from fluids related to granitoids or magmatic systems and the gold deposits with the last two mineral assemblages originated from undercasing non-magmatic fluids.
