鄂尔多斯沙漠高原白垩系地下水锶同位素的演化机理
Strontium isotope evolution mechanism of the Cretaceous groundwater in Ordos Desert Plateau
摘要
Abstract
Combined with groundwater chemistry data and using Sr content and 87 Sr/86 Sr 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 87 Sr/86 Sr ratios and the 87 Sr/86 Sr ratios of groundwater are between 0. 709871 and 0. 711792. Sr in groundwater is primarily derived from carbonate minerals, sulfate minerals and plagioclase of silicate minerals. The water-rock interactions in the groundwater of Huan River Group in the Cretaceous aquifer are mainly carbonate mineral dissolution, sulfate mineral dissolution and plagioclase dissolution,and the interactions of Luo River Group are sulfate mineral dissolution and K-feldspar dissolution. The main water-rock interactions include the carbonate mineral dissolution,sulfate mineral dissolution and silicate mineral dissolution in the Cretaceous aquifer of Ordos Desert Plateau.关键词
