摘要 最新水文钻孔和露头剖面调查测试资料对鄂尔多斯盆地白垩系含水砂岩的组分特征和空间分布综合研究表明,宜君-洛河含水岩组广泛分布于全盆地,为最主要的区域性含水岩组,以长石石英砂岩、长石砂岩、岩屑长石砂岩发育为主;华池-环河含水岩组分布广泛,也是很好的含水岩组,主要为长石砂岩、长石石英砂岩、岩屑长石砂岩;罗汉洞-泾川含水岩组仅局限于盆地北部和西部,是一套比较局部的含水层,主要为长石石英砂岩和岩屑石英砂岩。总体上,盆地北部白垩系含水砂岩极其发育,南部含水砂岩具多层分布的特点,厚度总体较小。 The research for the latest data on hydrological boreholes and outcrop sections indicates that the Cretaceous Yijun-Luohe aquifer formation widely exposed in the Ordos Basin consists mainly of feldspathic quartzose sandstone, arkose and lithic arkose. The Huachi-Huanhe aquifer formation is another important formation, which can be found throughout the basin and consists mainly of feldspathic quartzose sandstone, arkose and lithic arkose, too. The Luohandong-Jingchuan aquifer formation as a partial aquifer is only exposed in north and west of the basin and consists of feldspathic quartzose sandstone and lithic quartzose sandstone. As a whole, Cretaceous aquifer sandstone is well developed in the north, and characterized by multiple beds with a small thickness in the south.
