摘要
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。
Based on exploration and research in recent years and on the state of exploration and utilization of geothermal resources,the hosted regularities and genesis of geothermal resources in Nanyang City has systematically studied in detail in the paper.Nanyang broken basin can be named as 'hot basin'and Nanyang City is located in the northern'hot basin'.The results of exploration and researching manifest that underground hot water are mainly abound in sedimentary layer of sandstone and rock fracture of marble which are both within and under Tertiary system.The genesis is the superposition of runoff conduction of sedimentary geotherm with the upward convection of heat water (or steam) in deep part along deep,large fracture and the radioactive spallation heat.
