| 摘 要： | 河南省栾川县九龙山汤池温泉出露于马超营断裂与葫芦沟断裂交会部位的破碎带上,热储呈带状分布。研究表明,热储属中低温地热田Ⅱ类2型,地热流体呈上升泉出露,出露标高521m,水温多为69℃,为氟.硅型医疗热矿水。温泉成因机制为:马超营断裂与葫芦沟断裂交会地段岩石破碎十分强烈,从而使地球深部的岩浆入侵,将热量向上传送,形成地热异常区(即储热断裂构造);断裂切截了地壳深部高温岩体,形成的宽度数十米至上百米的构造破碎带为地下水的渗入、运移和储存提供了空间。温泉大气降水的补给,由于断裂带内围岩蚀变强烈,经过水岩的长期接触、长时间的补给、径流及高温高压的溶滤和化学作用,为地热水中有益元素的来源奠定了物质基础。

| Abstract: | Tangchi hot spring is located in the intersection fractural zone of Machaying fault and Hulugou fault in Jiulongshan mountain area in Luanchuan,Henan Province.The geothermal spring distributes in ribbon type,which belongs to mid-lower temperature geothermal fileds II2.This hot spring is an ascension spring which exposed at the elevation of 521 m and the average water temperature is 69℃.It belongs to the type of fluorine-silicon(Si) recombination hot spring.The formation mechanism is that the rock in interaction of Machaying fault and Hulugou fault is fractural,which allows encroaching of igneous magma from deep earth.The thermal goes up and forms the abnomal geothermal zone(geothermal fault structure).The fault cuts the high temperature rockmass and forms the 10-100 m width fracture belt,which supplies the good condition for the water infiltration,flowing and storing.The hot water source of geothermal spring is precipitation.After a long time ineraction between water and rocks,the lixiviation under high temperature and pressure and chemical action,the rock provides abundant mineral element for hot water. |
