摘要
本文根据从横径地区获得的温泉水、气体和同位素化学成分资料 ,系统地研究了该区地热水的成因。水、气体、同位素地球化学研究表明 ,横径地区地热水的形成与岩浆和火山活动无关 ;地热水主要起源于大气降水 ,其中气体组分起源于大气、地壳和地幔的混合 ;地热水处在中低温的地热储中 ;地热水的补给区位于乌泥嶂地区 ,其补给区可能的高程为 3 3 7 5～ 743 6m。
The studies of water, gas and isotope chemistry indicate that the formation of geothermal water in Henjing area is not related to the magmatic and volcanic sources. The geothermal water mainly derives from the meteoric source, which the gas components originate from the mixing of meteoric, crust and mantle sources. Moreover the geothermal water is in a low to moderate temperature geothermal reservoir. Based on isotopic data, the possible elevation of recharge water is about 337.5m to 743.6m, which corresponds to Wunizhang area.
