据国外地热研究论述,一地区的地热状况,首先取决于该区所处大地构造部位及地壳稳定程度。 世界地热带一般常出现在地壳各大板块边界附近,高热流的部位常在俯冲带前端。地壳变动剧烈地区,为中、新生代造山带往往是地热异常区,而板块内部地壳稳定部位,如古老地盾地台区,地热状况较 According to the study of geothermal in foreign countries, geothermal conditions in a region depend primarily on the stability of the earth’s tectonics and the crust in the area. Generally, the world’s geothermal belt is usually found near the boundaries of major plate boundaries of the crust, and the site of high heat flux is often at the front of the subduction zone. The crustal changes in the violent areas, for the Mesozoic or Cenozoic orogenic belt is often geothermal anomalous area, and plate internal crustal stability areas, such as the ancient shield plateau area, geothermal conditions than
