| 中文摘要: |
| 在对赛什塘的野外地质调研的基础上,文章总结归纳了与成矿有关的矿床地质特征。同时结合室内相关岩矿鉴定及部分矿床地球化学分析,重点针对前人提出的喷流沉积型成因的相关论据进行逐一分析讨论,对喷流沉积的观点提出了质疑；然后进一步讨论了大地构造背景、矿体地质特征及其他地质地球化学特征,分析其成矿作用过程,最后得出赛什塘铜矿的形成与石英闪长岩密切相关,整体上是夕卡岩化的结果。赛什塘铜矿的形成并未显示明确的喷流沉积过程,其成因类型应为夕卡岩型。 |
| 英文摘要: |
| On the basis of the detailed field investigation, the paper summarizes the geological characteristics of the Saishitang copper deposit. In combination of the microscopic petro-graphic study and geochemical characteristics analysis of the deposit, the authors discussed the each evidence to support the deposit genesis as the seafloor exhalative deposit proposed by the previous researchers, and proposed different view about the deposit genesis. Furthermore,the tectonic setting, geological features of orebody and other geological and geochemical characteristics of the deposit were discussed, the mineralization process was analyzed. It is concluded that the formation of the Saishitang copper deposit is closely related to the quartz diorite porphyry and is the final product of the skarnization process. In summary, the Saishitang copper deposit belongs to the skarn type and there is no clear exhalative sedimentary process in the deposit area. |
