山东泰山桃花峪地热氡泉水化学演化及氡富集机制
Hydrochemical Evolution and Driving Mechanism of Radon Enrichment of Geothermal Radon Spring in Taohuayu Area in Mount Taishan in Shandong Province
摘要
Abstract
Taohuayu geothermal radon spring is a scarce resource with notable therapeutic and health-pro-moting potential.Relying on regional geological structure background,by using graphical analysis,ion composition ratio and mineral saturation index calculation,hydrochemical evolution laws of geothermal water and the driving mechanism of radon enrichment in the area have been studied.It is indicated that hot water in geothermal field belongs to SO4-Na·Ca type,which can be named as fluorine-metasilicic acid-radon composite hot mineral water.The geothermal water is of steam heated water type,and the water rock interaction is in the transition stage from immature water to partially balanced water,with obvious cold water mixing.The mixing ratio of cold and hot water bodies is 0.63～0.71.The ion composition of water bodies is mainly controlled by the leaching and cation exchange of silicate minerals.Sulfuric acid o-riginates from deep reducing environment and migrates along the fault zone to shallow oxidizing environ-ment through H2S oxidation.Rich uranium sulfur granite can provide material basis for radon enrichment,while the fault fracture zone provide spatial channels for radon migration and accumulation.Fault activity,tectonic shear,hydrothermal alteration,and seismic activity jointly promote radon enrichment.This study can provide theoretical support for exploration,development and utilization of similar geothermal radon spring resources.关键词
