| 摘 要： | 赋存在前寒武纪地质体中的金矿产,除外生者与地质体沉积期为同时代形成,但一般还有沉积期后内生成矿作用叠加、改造者以外,其他内生金矿产则可能与火山喷发-沉积或岩)或侵入成岩同期,也可能是在成岩期后的前寒武纪构造-岩浆作用下新生、改造和叠加形成,还可以在显生宇地槽阶段、地洼阶段的强烈构造-岩浆作用下新生、改造和叠加形成。本文重点讨论其形成时代的判别及在地洼阶段形成、并赋存在前寒武纪地质体中的金矿产。

METALLOGENETIC EPOCH OF GOLD HOSTED IN PRECAMBRIAN GEOLOGIC BODY |

| Abstract: | The gold mineral product, with the exception of the exogenetie ore deposit, hosted in Precambrian geologic body has possible following metallogenetic epoches:① Some have been formed simultaneously with the volcanic eruption-sedimentary (diagenetic) process or the magmatic invasion (segregation); ②A number of were regenerated (remade) or diplo- ectono-magmatism after their host rock was formed; ③A number of were regenerated (remade)
or diplogenerated by Phanerozoic (geosynclmal and diwa ages) tectono-magmatism. In this article are mainly inquired judgment way to the gold metallogenetic epoch and the gold mineral deposit formed in the diwa age and hosted in Precambrian geologic body. |
