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。 |

Tianzhu is one of the most important barite origin of China,more than 200 million ton is provedFrom 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 scaleAccording to the deposit characteristics and metallogenic condition,it’s thought the barite deposit is controlled by strata lithology,ancient sedimentary basin and contemporaneous faultAccording 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 upFor the regional metallogenic background,it’s thought to have big prospecting potential in the core and limb of Pingdi syncline in Tianzhu |
