| 摘 要： | 半宽金矿床的成矿物质具有多源性.微量元素特征显示金矿床的成矿物质来自混合岩.同位素研究表明含矿流体为岩浆成因,但有变质流体和天水的混合.稀土元素特征反映矿质来自下地壳或地幔,是下地壳物质重熔的结果,但受到上壳岩石的混染.矿床的成因为岩浆活化的金矿床.

| Abstract: | Bankuan gold deposit,located in the north part of the basement uplift of Xiaoshan terrain,is of multi source of ore forming material.The features of minor elements show that the ore forming material was derived from migmatite.Study of isotopes proves the magmatic origin of ore bearing fluid,which was then mixed with metamorphic fluid and meteoric water.REE data suggest that the ore forming material should be from the lower crust or the mantle It was resulted from the remelting of lower crustal material and the hybridization of upper crustal rocks The deposit is genetically a magmatic mobilized gold deposit |

| Keywords: | gold deposit material source genesis magmatic mobilization Henan Province |
