摘要
温泉的岀露严格受哀牢山帚状构造中断裂带控制,在本异常带岩浆活动较强烈,活动性断裂和变质岩网状裂隙为热水循环和赋存提供了有利条件。研究表明,区内热田热源主要为:岩浆余热、放射热、机械热。热流体化学分析表明,热水化学成分随水温变化而变化,地热水水化学类型以SO_4-Ca·Na+K型为主。通过地热温标计算,得出K^Mg温标更适用于该类型中低温地热田热储层温度的估算。
The appearance of hotspring is strictly controlled by fault zone of brush structure in Ailao Mountain.Studies have shown that it has intensive igneous activity of this anomaly zones,and the active fault and mesh cracks of metamorphic rocks have provided advantages for the hot water circulation and occurrence.The heat source of geothermal field：magma heat,radiant heat,mechanical heat.Thermal Fluid Chemical analysis shows that the chemical composition of the hot water changes with the changing water temperatures,and the hydrochemical type of geothermal water is mainly SO_4-Ca·Na ＋ K type;By the calculation of geothermometer,it obtains that the K^Mg thermometric scale is more suitable for the estimation of heat reservoir temperature of geothermal field of this type.
