荷花山铅锌矿与铜陵地区其它矿床成矿控制因素的对比研究

Comparative Study on the Controlling Factors of Hehuashan Lead-zinc Deposit and Other Deposits in Tongling Area

为了探讨荷花山铅锌矿控矿因素上与铜陵地区其它矿床异同,运用宏、微观相结合,地质观察研究同位素地球化学以及流体包裹体分析相结合的方法,通过地层岩性、地质构造、特定地质体及成矿流体的来源和性质等几个方面与成矿关系的比较,揭示了这种新类型矿床的控矿因素的特点是与岩浆关系不密切的低温热液、角砾岩控矿。得出了这种新类型矿床既具有铜陵地区其它矿床的控矿因素,同时也具有自己独特的控矿因素的结论。

In order to explore the similarities and differences between the ore-concentration factors of the Hehuashan lead-zinc deposit and other deposits in the Tonglimg area,the paper uses macroscopic and microscopic combination,geological observation to study the combination of istotope geochemistry and fluid inclusion analysis,theough stratigraphic lithology,geological structure,The comparison of the source and nature of specific geological bodies and ore-forming fluids with mineralization,reveals that the ore-controlling factors of this new type of deposit are characterized by lowtem-perature hydrothermal and breccia control that are not closely related to magma.It is concluded that this new type of deposit has the ore-controlling factors of other deposits in the Tonglimg area and also has its own unique ore-controlling factors.
