摘要
根据岩心、薄片和测井资料,并结合古地貌分析,认为鄂尔多斯盆地东部发育多期岩溶,马四期前因盐刺穿构造作用,地层抬升,马三段地层被剥蚀,形成"后马三期"新的一期岩溶作用。岩溶塌陷发育受控于断裂和底劈作用,并沿断裂带分布。
According to the core, thin slice and logging data, combined with the analysis of the ancient landform, it is considered that there are many stages of karst in the east of Ordos basin,The Ma four antecedents of salt diapir tectonic uplift, Ma three strata denudation, forming ＂after Ma three＂ a new stage of karst.The development of karst collapse is controlled by fracture and bottom splitting, and is distributed along the fault zone.
