贵州省南部地区是全国重要的汞、锑资源分布区。2000年由于产于上泥盆统中铅锌矿的陆续发现,贵州省地矿局启动了以铅锌资源评价和成矿规律研究为主的地质工作,目标是总结铅锌矿产出的地质特征和成矿规律。通过三年的研究认为,该区处扬子准地台、华南褶皱带和右江造山带交汇部位,受晚古生代初期发生的陆内裂谷活动影响,产生了一个与桂中台陷相连的大型沉积凹陷区—黔南台陷沉积区,形成了巨厚碳酸盐和碎屑岩沉积,产生了与裂陷盆地边缘同沉积断层活动有关的低温成矿作用,造成了在晚泥盆纪以前的地层中汞、锑、砷、金、铅锌等矿床沿同沉积断层密集分布。本文通过矿床特征总结和矿床成因探讨,建立了准同生沉积成矿作用模式,旨在为该区寻找这类矿床提供参考和借鉴作用。
The southern part of Guizhou Province is an important distribution area of mercury and antimony resources in the country. In 2000, due to the successive discovery of lead-zinc deposits in Upper Devonian, Guizhou Bureau of Geology and Mineral Resources started the geological work mainly on the research of lead-zinc resource evaluation and metallogenic regularity with the goal of summarizing the geological features of lead-zinc mine output And metallogenic regularity. After three years of research, it is believed that the junction of the Yangtze Platform, the South China Fold Belt and the Youjiang Orogenic Belt at the junction of the two regions was affected by the intracontinental rifting in the early Late Paleozoic and resulted in a large-scale Sedimentary depressions - the southern Qianjiang sag sedimentary region formed thick carbonate and clastic sediments, resulting in the marginal synoptic fault activity in the basin-related low-temperature mineralization, resulting in the late Devonian Strata of mercury, antimony, arsenic, gold, lead and zinc deposits along the same sedimentary-intensive distribution. Based on the summary of deposit characteristics and the genesis of the deposit, this paper establishes a quasi-syngenetic sedimentary metallogenic model to provide reference and reference for the area to find such deposits.
