摘要
以板块构造理论为指导,依据矿床在成矿作用、主要控矿因素、矿石建造和组构、容矿岩石建造等方面的特征对已知金矿划分为6个系列17种成因类型,并举例说明了各类金矿在不同岩石建造中的表现样式,将所有金矿归结为内生和外生两个群。
17 types and 6 series of gold deposits shown in the following table are classified based on metallo-genesis,principal metallogenic facters, minerological association,structure and texture of ore and nature of host rost assemblage. The patterns of different type gold deposits are briefly described according to the nature of host rock assemblages.
Endogenic group A. magma bound series : explosive breccia , porphyry and skarn types.
B. fault bound series: fine grain dissemination, altered crush zone , quartz vein and silicified lode types.
C. strata bound series: iron formation bound , carboniferous bed bound and conglomerate bound series types
D. stratiform series : massive sulfide and hot spring types.
Exogenic group E. weathering crust bound series: red soil and iron cap types.
F. detrital series : conglomerate , tillite and placers types.
