The Strontium Isotopic Chemical Analysis of Geothermal Water in Guihu, Fuzhou

Abstract:

This paper takes Fuzhou Guihu geothermal field as the research object, analyzing its geothermal background of regional tectonic characteristics. With the increase of flow path, contents of carbonate and aluminosilicate minerals both raises, while 87Sr/86Sr goes down gradually. 87Sr/86Sr in discharge regions of geothermal water is the lowest. Analysis of the geothermal water chemistry and isotopic characteristics lead to the conclusion that the underground water circular depth of wells located on the alluvia and proluvial fans in front of mountains is relatively deep, which reaches 500-700m. Average of the mixed ratio is 0.14, which means that 14% cold water is mixed.
