| 摘 要： | 通过对吉林天宝山多金属矿床地质特征的分析、研究,提出了叠加成矿作用的观点。文中用因子分析法探讨了不同成矿作用下矿化元素的特点,讨论了矿物包裹体测温结果和S、Pb、O、H同位素组成特征。形成矿床的三种成矿作用是:以锌矿化为主的二叠纪海相火山热液成矿作用;以铜矿化为特征的晚海西期岩浆热液成矿作用;以铅、锌矿化为主的三叠纪次火山热液成矿作用。受同化混染和矽卡岩化作用的影响,区内碳酸盐地层提供了部分成矿物质。最后,总结了此类复式成因矿床的一般地质特征。

| Abstract: | The pollymetallic deposit is located near the south margin of Jilin-Hei-longjiang hercynian fold zone and tectonically adjacent to Helong fault block.On the basis of the geological feature of the deposit, the author holds it to belong to a polygenetic origin.Factor analysis is used to seek out the characteristic or ore-forming elements in different mineralization. Inclusion trap temperature and Pb,S,O,H isotope composition are also discussed. Three kinds of ore forming processes are determined as follows; Permian oceanic volcanohydrothermal mineralization signified by Zn;late Hercynian magma-tic hydrothermal mineralization characterized by Cu; Triassic subvolcanic hydrothermal specialized in Pb and Zn. These ore-forming processes are genetically related with the contemporaneous or adjacent volcanic-intrusive events. Finally, the general geology of this king of ore deposit is summarized. |
