摘要
依据航磁资料对鄂尔多斯盆地北部基底结构及起伏形态、基底大断裂对盆地发展的控制作用提出了一些看法 ,并据地球物理场特征加以描述。通过研究 ,认为伊盟南部和西部是深凹陷。同时 ,利用Parker法对重磁资料进行联合计算 ,对寒武—奥陶系的厚度及分布范围加以确定 ,为今后进行深层油气勘探提供了依据 ,还对盆地的构造发展及盖层的发育特点进行了探讨。
Based on aeromagnetic data,the author advances some opinions on the basement structure and relief of northern Ordos basin as well as the controlling role of the basement fault in the development of the basin,and makes description from characteristics of geophysical fields.Studies show that the southern part and western part of Ih Ju League constitute a deep depression.With Parker method,this paper has made combined calculation for gravity and magnetic data and determined the thickness and distribution of Cambrian Ordovician strata,thus providing grounds for oil and gas exploration at depth.The tectonic development of the basin and characteristics of the cover are also discussed.
