| 摘 要： | 贵州及邻省区产于局限台地蒸发相和台地边缘斜坡相碳酸盐岩中的汞矿，与蒸发岩和油气存在广泛地地层和区域伴生关系。与蒸发相有关的汞矿，多属贫矿，绝大部分为单汞矿床，围岩蚀变以与硬石膏有关的假层状方解石化为主，与台地边缘斜坡相有关的汞矿，多为中－高品位矿石，相当部分为汞与其它元素（如Se,Tl,Au,Mo,Ni,As）等，伴生的矿床，围岩蚀变以硅化为主，矿石中辰砂常与碳沥青共生，碳沥青的存在，表明地质历史上确实有过生油过程。

| Abstract: | The mercury deposits, produced in the carbonate rocks from the evaporation facies of the limit platform and the slope facies of the platform edge in Guizhou and neighboring areas, have broadly associated relationship with the evaporites and the oil gas in stratum and region. The mercury deposits related to the evaporites mostly belong to the poor deposits, of which greater parts are single mercury deposits and the alteration of the host rock give priority to the similar bedded calcitization in relation to the anhydrite. Most of mercury deposits beared on the slope facies of the platform edge are middle-high grade ores, the considerable parts of the deposits are the associated deposits of the mercury and the elements else (i.e. Se, Ti, Au, Mo, N, Ni, As), their alteration of the host rock is principal in silicification, and the cinnabar frequently keep paragenesis with the carbonate asphalts in the ores, it shows there occur the oil-generating progress in the earth history |
