| 中文摘要:山东夏甸金矿矿床成因一直有变质热液、岩浆热液和天水之争。经过工作得知，还有幔源流体加入成矿，其主要证据有：①招平深大断裂带存在，为幔源流体加入成矿提供了通道；②金矿脉与中基性脉岩相互交切、相伴产生；③S、H、O、C等同位素测定值表明，含金流体主要来自幔源。 |

| A Tentative Discussion on Mantle Fluids in the Xiadian Gold Deposit, Shandong Province |
|
|
| Abstract:There has been long controversy on the genesis of the Xiadian gold deposit. Some hold that it is of metamorphic hydrothermal origin, others argue for magmatic hydrothermal genesis, and still others think that it results from ground water.Nevertheless,further work shows that the mantle fluids might have played an important role in the formation of the deposit. The main evidence is:①the Xiadian gold deposit is located in the Zhaoping deep fault;②the gold veins are usually associated with the intermediate basic rock veins;③the estimated S,H,O and C isotopic values indicate that gold bearing fluids mainly came from the mantle fluids. |
