| 摘 要： | 有关本区矿床成因先后有同生沉积、低温超低温热液、沉积改造等不同看法。本文根据宏观、微观资料的初步分析认为,本区铅锌矿床属于后成深循环热卤水成因——后成层控矿床。本文将对这一问题进行讨论。

| Abstract: | The stratabound lead-zine ore deposits in the study region occur mainly in the upper Cambrian algal limestone. They are controlled by the stratigraphy, lithology and structures. The evidence of magmatic activity has not been found there. There is no evidence on synsedimentary and diagenetic ores in the ore deposits and surrounding rocks, thereby, it is clear that the ore deposits have an epigenetic origin. The results of S-isotopic determination show that the source of S is chiefly the juvenile water, brine in oil field and the vadose brine. The great changes in Pb-isotopic composition indicate that, it comes directly from strata. The barite and anthraxolite are common and salt can be seen in the deposits mentioned-abovte. The temperature determined with fluid inclusions in sphalerite ranges from 60 to 280℃. To sum up, the ore deposits under investigation were generated by the deep circulating hot brine. |
