| 摘 要： | 矿化剂元素硫(S)是绝大多数有色金属矿床成矿矿物中必不可少的组成物质,其对矿床形成的直接控制作用不言而喻。在目前收集到的文献资料中,有关S的研究多集中在示踪成矿流体来源方面,而关于地质体中S初始富集及其在成矿过程中的活动特性对成矿的控制却少有涉及。本科研团队历经十余年,在40多个矿床上对矿化剂元素S与成矿进行了系统研究,结果发现,热液成因矿床均产出在富S地质体中,地质体中S的富集与赋矿围岩同期形成,而且伴生有成矿元素的富集,构成初始矿源,奠定成矿物质基础。热液活动期间,初始矿源中矿化剂元素S及成矿元素发生活化、迁移和再富集,是控制成矿的直接因素。青海野马泉铁多金属矿研究结果证实,试验区灰岩中S的富集与灰岩同期形成,同时伴生有Pb、Zn、Ag、Cu等富集,构成矿源层。后期热液作用主导矿源层中S与成矿元素活化、迁移和再富集是成矿的必要条件,矿源层的沉积环境具有其特殊性。此项研究成果对矿床形成机制研究和矿床地球化学勘查均具有借鉴价值。

| Abstract: | Sulfur, as a mineralizing agent, is indispensable to most of the non ferrous metal ore deposits, contributing to the formation of ore mineral. Nowadays, the researches on S mainly focus on tracing the sources of ore forming fluids, whilst little on its initial enrichment in geologic body and its mineral controlling activities in mineralization. Through a 10 year systematic research on the relationship between S and ore forming processes in more than 40 ore mineral deposits, it is found that all the hydrothermal ore mineral deposits are seated at S rich area. The enrichment of S and the formation of ore bearing rock take place in the same time, accompanied by the enrichment of the ore forming elements which forms the initial source of ore forming substance and lays the foundation of ore mineral formation. It is the direct reason that S and ore forming elements in the initial source of ore forming substance are activated, transported, and re enriched This paper sets Yemaquan test area, Qinghai, as an example to elaborate the above results and new discovery. The results of the study on Yemaquan Fe polymetallic deposit, Qinghai Province, show that the enrichment of S in limestone was happened at the same time as the formation of limestone, accompanied by the enrichments of Pb, Zn, and Cu, forming the ore source. The activation, transportation, and re enrichment of S and ore forming elements, which were led by post mineralization, are necessary to ore forming process. The sedimentary environment of ore source is of special significance. This study is of some reference value for researches on ore forming mechanism and exploration geochemistry. |
