摘要
紫云县地处贵州省南西部,区域上无岩浆活动,地表无温泉地热流体露头和无明显的其他地热显示,增加了地热勘查的难度。燕山期自东往西的构造应力作用下,产生了近南北向、北东向断层和近南北向褶皱的主体构造,以及碳酸盐岩—碎屑岩沉积建造为区内地热资源的产生提供了前提条件;采用基础地质结合物探方法研究优选出了层状热储较好的牛场坡背斜和带状热储F4小桥断裂结合的有利部位,施工了地热钻孔,取得了良好的地热水找矿成果。
There is no outcrop of magmatic rock and thermal spring in Ziyun County,Guizhou Province.The Yanshanian longitudinal and NE-trending faults and folds and carbonate rock and clastic rock formation provided the precondition for the generation of geothermal resources in the region.The junction of the Niuchang anticline and the Xiaoqiao fault is selected as geothermal drill hole location based on basic geological research in combination with geophysical method,which achieves good results.
