| 摘 要： | 白垩纪鄂尔多斯盆地在燕山期抬升-沉降及气候演变的背景条件下,受水力、风力等地质作用,经历了早白垩世宜君-洛河期→环河期与罗汉洞期→泾川期两个沙漠沉积演化阶段。其中,洛河期和罗汉洞期是沙漠发育的两个主要时期,形成了旱谷、沙丘、丘间及沙漠湖等多类型沙漠亚相碎屑岩沉积。沙丘沉积砂岩作为白垩系沙漠相最主要的沉积岩石,具有分布稳定、厚度巨大、含盐量低、孔隙空间发育、储水性和透水性强等特点,不但具有良好的地下水赋存和循环条件,而且一般赋存着水质较好的地下水。

| Abstract: | During Cretaceous, Ordos Basin had gone two desert sedimentation evolution stages involved from Yijun-Luohe stage to Huanhe stage and from Luohandong stage to Jingchuan stage, controlled by areolation and hydro dynamism, under the climate evolution and tectonic lifting and subsidence. Luohe stage and Luohandong stage are two major sedimentation stages of desert facies, desert facies can be divided five sub-facies such as gobis, wades, dunes, inter-dunes, and desert lakes. Among them, sandstones of dunes are the most important desert sediments of Cretaceous; they have many pores, big thickness, stable distribution, lower salt content, and good capability of water-bearing, water-leading, water penetrating. So, dunes sediments not only have good groundwater occurrence-circulationconditions, but also bear groundwater of better quality. |
