| 摘 要： | 依据鄂尔多斯盆地古构造古地理背景、古水动力以及古气候条件,结合单井沉积相分析建立了马家沟组障壁潟湖沉积相模式,该模式分三个阶段即与海侵期相对应的以灰岩沉积为主的障壁潟湖沉积阶段(阶段Ⅰ)、与海退相对应的以灰岩夹蒸发岩沉积为主的障壁咸化潟湖沉积阶段(阶段Ⅱ)和与低海平面期对应的以膏岩盐沉积为主的障壁膏盐湖沉积阶段(阶段Ⅲ...

| Abstract: | Lower Ordovician Majiagou Formation is composed of six members in which Ma1,Ma3 and Ma5 are evaporate including dolomite,anhydrite and salt and Ma2,Ma4,Ma6 are limestone with dolomite in Ordos Basin.Majiagou Formation is formed by cyclic sedimentation by intermeshed evaporite and carbonate.Upwarps around the basin and a downwarp in the centre of the basin constitute the Early-Ordovician Palaeogeomorphologic pattern.Upwarps as underwater barriers led to exchange limitation between lagoon and exterior sea and... |
