摘要
通过野外观察和铅、硫、碳同位素测定、稀土元素组成、微量元素和包裹体资料,对该矿床成矿物质的来源作了系统分析,表明金属元素主要来自围岩灯影组,硫具有地层硫与非生物还原硫的混合来源,脉石碳酸盐矿物中的碳来自围岩碳酸盐岩的溶解,重结晶,但混入有有机碳,介质(水)主要来自大气降水。
Through field observation,analyses of compositon of lead, sulphur and carbon isotops,REE, trace elements and inclusiohs, the source of ore-forming material of the Chipu lead-zinc ore deposit is discussed in this paper and have drawn such following conclusions: the ore-forming materials are of polygene. Its metal elements mainly come from wall rock-Dengying Formation;sulphur comes from stratic sulphur and nonbiological reducting sulphur; carbon in the gangue carbonate mineral is formed by the dissolving and recrystallizing of the surounding carbonate rock,but mixed with some organic carbon; medium (watar) mainly comes from precipitation.
