产于太古宙岩石中的四种类型金矿床,无一例外地都具有明显的后生性、伴生性和叠生性,可划属同生构造型矿床(褶皱区)和叠生构造型矿床(断块区)。小秦岭金矿带的实际地质资料表明,金矿床与褶皱作用和与之同步形成的剪滑断裂,以及随后叠加的脆性断裂等多期动力变形—变质(混合岩化)环境相联系。因此,找矿工作应着眼于成矿作用的特殊地球动力学环境,从不同地区的具体条件出发。
The four types of gold deposits produced in the Archean rocks show obvious epigenetic, associative and superimposed characteristics, all of which can be classified into syngenetic tectonic deposits (fold zones) and superimposed tectonic deposits Block area). The actual geologic data of the Xiaoqinling gold belt show that the gold deposits are associated with fold and synchrotron shear-slip faults and subsequent superimposed brittle faults such as multistage dynamic deformation-metamorphism (mixed rockification). Therefore, the prospecting work should focus on the special geodynamic environment of mineralization, starting from the specific conditions in different regions.
