根据近些年勘探研究成果 ,结合部分已开发利用的地热资源情况 ,对南阳市地热资源的赋存规律和成因进行讨论。研究结果表明 :南阳断陷盆地为“热盆” ,南阳市位于“热盆”的边缘。地下热水主要赋存于第三系及以下的砂砾岩沉积层和大理岩裂隙中。成因是在沉积盆地型地热径流传导基础上 ,叠加以沿深大断裂带深部热水 (汽 )上升对流和放射性蜕变热的附加值而形成的。
According to the results of exploration and research in recent years and the development and utilization of geothermal resources in some areas, the occurrence laws and causes of geothermal resources in Nanyang City are discussed. The results show that the Nanyang fault basin is a “hot basin”, and Nanyang City is located at the edge of the “hot basin”. Underground hot water mainly occurs in glutenite sediments and marble fractures in the Tertiary and below. The formation is based on the geothermal runoff in the sedimentary basin and is superimposed with the added value of convective heat and radiative decay heat along the deep hot water (vapor) in the deep major fault zone.
