中国北东部的金矿床具有多因复成特点。大地构造发展阶段的“活动期”是金成矿的有利时期。后一阶段继承并改造前一阶段的金矿床或矿源层,使之形成新的金矿。这个地区金的成矿期主要有两个:一是晚太古-早元古代(前震旦纪结晶基底层中);一是中新生代(地洼构造层)。金矿床主要分布在地洼区四级单元——地穹或地穹与后地洼交接带或地洼区的更次一级正单元中。
The gold deposits in the northeastern part of China have many complex features. The “active period” of the geotectonic development stage is a favorable period of gold mineralization. The latter stage inherited and transformed the gold deposit or source layer of the previous stage to form a new gold mine. There are mainly two gold mineralization stages in this area: Late Late Archean-Early Proterozoic (Pre-Sinian crystalline basement); and Mesozoic-Cenozoic (Diwa structural layer). The gold deposits are mainly distributed in the next more positive units of the fourth level unit in Diwa district - the junction between the dome or the dome and the posterior dike or the depression.
