- Abstract:
- We have studied the Liuhuangdong spring to evaluate whether it is suited for monitoring earthquakes,including hydrochemical type,water cycle characteristics,and formation mechanism.The results indicate that the hydrochemical type of spring is of HCO3·SO4-Ca·Mg.The water originates from a geothermal reservoir at about 4 742.5 m depth and supplies by meteoric water at about 2 200～2 300 m altitude.The temperature of the geothermal reservoir is about 210 ℃.The circulation depth of spring is the same as the preferred plane of focal depth in this area.The research results show that the Liuhuangdong spring mainly comes from rainfall infiltration.The rainfall is heated by the surrounding rock during the runoff.Then,it comes out along the Dabaoshan fault.Hence,the Liuhuangdong spring plays an important role in earthquakes formation in this area.Due to the strong seismic activity of the Dabaoshan fault,the Liuhuangdong spring with a deep circulation is suited for earthquakes monitoring.
