内蒙古东升庙铅锌多金属硫化物矿床位于华北板块北缘西段的狼山多金属成矿带内,铅锌储量达超大型,自上世纪七十年代一直在开采利用。尽管可能有少量岩浆来源硫的参与,东升庙矿床的硫被认为总体上来源于海水硫酸盐的还原(李兆龙,1986;夏学惠,1992)。然而东升庙矿床常见的后生组构特征指示相当一部分硫是来源于热液流体,并不是来自海水中溶解硫酸盐的直接还原。根据国内外铅锌矿床研究,含矿岩系中的蒸发岩地层可以作为矿石硫的重要来源。目前与东升庙矿床硫的蒸发岩
The Dongshengmiao lead-zinc polymetallic sulphide deposit in Inner Mongolia is located within the Langshan polymetallic metallogenic belt in the western segment of the northern margin of the North China Plate. Its lead and zinc reserves have been extremely large and have been exploited since the 1970s. Sulfur in the Dongshengmiao deposit is considered to be derived, in general, from the reduction of seawater sulfate (Li Zhaolong, 1986; Xia Xuehui, 1992), although a small amount of magma-derived sulfur may be involved. However, the common epigenetic structures of the Dongshengmiao deposit indicate that a considerable part of sulfur is derived from hydrothermal fluids and not from the direct reduction of dissolved sulphate in seawater. According to the research of lead-zinc deposits at home and abroad, the evaporite formation in the ore-bearing rock series can be used as an important source of ore sulfur. Sulfur evaporation of the Dongshengmiao deposit currently
