Hydrogeochemical and isotopic characteristics of the karst groundwater systems in Longzici spring basin
摘要
Abstract
Through the investigation and analysis of 35 samplesin Longzici spring basin,the hydrochemical characteristics were made by Shukallev classification.Karst groundwater is mainly composed of SO4 · HCO3-Ca · Mg,the sulfate ion plays an important role in water chemistry and water quality.Sulfate ion of two kinds of sources mainly comes from gypsum or pyrite oxidation.The source of replenishment of groundwater in Longzici spring basin is fossilwater and modern,from the test results of hydrogen and oxygen isotopes.Isotope analysis shows that the proportion of sulfate ion in coal measure strata is 22％,which indicates that the geochemical background of the spring area is an important factor for the pollution of karst groundwater.But compared with the calculation of sulfur isotope results in 2004 14.37％),the proportion of SO42-in coal-bearing strata is significantly high 7.85％.关键词
