中文摘要: |
豫西金矿集区是全国最重要的矿集区之一,金矿赋存于古老的前寒武纪地层中,很多人认为金矿的成矿物质来源于这些古老地层。文章通过对区内金矿区含矿地层、化探异常、同位素资料及岩浆岩的分析后,认为金矿的成矿物质来源于地幔,这些古老地层仅仅是赋矿地层,并不提供主要成矿物质;而中酸性岩浆岩的侵入为深部物质向上迁移提供了很好的通道和热量,具有重要的控矿意义。 |
英文摘要: |
The western Henan is one of the Au deposit-clustered areas in China. Gold deposits here occur in the Pre-cambrain strata. It is generally considered that the ore materials are derived from the Pre-cambrain strata. However, careful analysis of the gold ore-bearing strata, geochemical anomlies, isotopic data and magmatic rocks shows derivation of the materials from mantle and the Pre-cambrain strata are only the gold ore-bearing strata and don't supply the materials. |
