辽宁省铁岭市柴河铅锌矿床成矿机理探讨

Metallogenic Mechanism of Chaihe Pb-Zn Deposit in Tieling

辽宁省铁岭市柴河铅锌矿床的成因,一直被地质界所重视。先后有岩浆期后中一低温热液矿床成矿、古地下水成矿、混合岩化成矿、层控型矿床的热卤水成矿等不同观点。分析矿床的成因的焦点主要是矿床成矿热液和矿质的来源问题。本文通过矿床的地质特征、同位素地球化学特征分析认为:辽宁省铁岭市柴河铅锌矿为深层变质热液改造型后生层控铅锌矿床。

Geological academic circles have paid more attention to the cause of formation of Chaihe Pb-Zn deposit all along. There are some different stand points about the cause of Chaihe Pb-Zn deposit such as post magmatic medium-cryogenic hydrothermal deposit; ancient subcutaneous water minerogentic deposit; magmatic minero-gentic deposit; strata bound hot bittern deposit. The central issue is the source of hydrothermal and mineral. The study on geological characteristic and isotope geochemical characteristic indicates that Chaihe Pb-Zn deposit is deep-level metamorphous hydrothermal reformed epigenetic strata bound deposit.
