中文摘要:
      贵州天柱是我国重晶石矿重要资源产地,已探明资源储量2亿多吨。2012—2014年通过天柱县重晶石矿整装勘查,在天柱坪地向斜北西翼发现新的重晶石资源,勘查证实达到大型规模。本文通过矿床特征、成矿条件分析,认为天柱重晶石矿床主要受地层岩性、古沉积盆地、同生断层的控制。以现代成矿作用理论为指导,本区地壳经历了地幔隆起→拉张(裂解)→聚合演化过程,建立区内重晶石矿形成大致经历海底喷流、沉积成矿的成矿模式。结合区域成矿背景分析,认为天柱坪地向斜核部和翼部仍有较大找矿潜力。
英文摘要:
      Tianzhu is one of the most important barite origin of China,more than 200 million ton is provedFrom 2012 to 2014,in the fully equipped exploration of barite,new barite resource was found in northwest limb of Pingdi syncline and proved to be big scaleAccording to the deposit characteristics and metallogenic condition,it’s thought the barite deposit is controlled by strata lithology,ancient sedimentary basin and contemporaneous faultAccording to the modern mineralization theory,the earthcrust in this area experienced the evolution process of mantle uplift-extension-aggregation,the metallogenic mode of barite which experienced submarine exhalation and sedimentary mineralization was built upFor the regional metallogenic background,it’s thought to have big prospecting potential in the core and limb of Pingdi syncline in Tianzhu
