Abstract

Abstract

Geothermal temperature is an important parameter for classifying the genetic types of geothermal systems and evaluating the geothermal resource potential.In order to rationally develop and utilize the geothermal resources in Zhaojue County of Sichuan Province, and consolidate the achievements of poverty alleviation, the geothermal temperature of the Zhuhe hot springs in this area was studied.Various methods were used to calculate its deep thermal storage temperature, including steam-free loss quartz and steam loss quartz temperature scales, chalcedony a and b, modified SiO₂ temperature scale, K-Mg, Na-Li, Na-K, Na-K-Ca and other cationic temperature scales.The reliability of the above methods is tested by Na-K-Mg triangulation method and mineral saturation index method.The results show that the average temperature calculated by SiO₂ (without steam loss) temperature scale method and modified SiO₂ temperature scale method are most suitable for this hot springs.The thermal temperature of its large hot springs ranges from 81℃ to 93℃, averaging 86℃, and that of small hot springs from 77℃ to 90℃, averaging 82℃.It reveals that the Zhuhe hot springs results from the deep terrestrial heat flow and is controlled by Mufoshan fault and Zhuhe fault.
