| 摘 要： | 东闯铅，金矿床是一大型石英脉型矿床，依据实际的观察，测试结果，论述了矿床的矿物充体包裹体地球化学特征，认为成矿溶液为Ｈ２Ｏ－ＣＯ２－ＮａＣｌ体系，富含Ｈ２，Ｎ２，ＣＯ，ＮＨ３，Ｈ２Ｓ，ＣＨ４及其他烃类气体，矿液呈弱酸性一弱碱性，还原条件，氧逸度低，温度高，矿液进入断裂扩容部位后发生的不混现象对矿质的沉淀有着重要影响，是一高温深成热液矿床。

| Abstract: | Dongchuang Pb Au deposit is a large quartz vein type deposit.From the study of fluid inclusions,it is coneluded:ore forming fluid belongs to H 2O CO 2 NaCl system,rich in H 2,N 2,CO,NH 3,H 2S,CH 4 and other hydrocarbon gases,with poorly acid weakly ,reduced condition,low oxygen fugacity,high temperture.Immiscibility occured affer ore fluid filled into flash parts of fault play a important role to ore forming element precipitation.The deposit is a high temperture plutonogenic hydrothermal deposit. |
