摘要
紫金矿业公司近年来完成了对内蒙古自治区乌拉特后旗东升庙矿区以东紧邻的三贵口地区的矿产普查工作,发现一超大型锌多金属硫铁矿床,随后完成了对三贵口南部的勘探。与其西部的东升庙矿床一样,三贵口矿床属于形成于中元古界狼山群二岩组石墨片岩和石墨白云质大理岩(原岩分别为泥质碎屑岩和白云岩)中的喷流沉积(SEDEX)型矿床,当时的形成环境为狼山裂陷槽中东升庙?三贵口同生盆地,同生断层控制了矿体的形成与展布。文章叙述了三贵口矿床的勘查过程,最后给出了对地质找矿工作的7点启示,再次验证了对矿床成因的认识程度往往决定了找矿勘查的成效。
Recently, Zijin Mining Company discovered a super-large zinc-multimetals-sulfur ore deposit in Sanguikou area, the east of Dongshengmiao ore deposit, Wulate Houqi, Inner Mongolia, China, after finishing the prospecting. And Zijin Mining then completed the detailed exploration of the southern block of Sanguikou area as the following work. Sanguikou ore deposit is a sedimentary exhalative （SEDEX） type one formed in the small Dongshengmiao-Sanguikou contemporaneous sedimentary basin （where the contemporaneous fault controlled the formation and distribution of ore bodies） of Langshan geosyncline at the Mesoproterozoic and hosted in the metamorphic rocks （graphite schist and graphite dolomitic marble, corresponding to mudrock and dolostone, respectively, as protolith） of the Second Formation of Langshan Group, the same as Dongshengmiao deposit. In this paper, I described the discovering process we did and discussed its implications for future exploration, which confirmed again that the understanding of genesis of ore deposit which most depends on careful observation and research on the site, in general, determined efficiency of exploration to some degree.
