| Abstract: | Combined with groundwater chemistry data and using Sr content and 87Sr/86Sr ratios of hydrous media and groundwater,this paper studies the mechanism of water-rock interaction in the Cretaceous aquifer of Ordos Desert Plateau.The result indicates that K-feldspar,plagioclase and carbonate minerals in hydrous media have different 87Sr/86Sr ratios and the 87Sr/86Sr ratios of groundwater are between 0.709871 and 0.711792.Sr in groundwater is primarily derived from carbonate minerals,sulfate minerals and plagiocl... |
