摘　　要：利用区域地震大剖面,结合地面地质调查成果,对鄂东南地区的深部地质结构及典型构造样式进行了分析,对上下地质结构的变异进行了探讨,提出志留系滑脱层之下的“原地体”具有变形相对较弱、褶皱宽缓开阔的特点,在后期拉张改造中受到上盘“异地体”的保护,应是有利的油气勘探领域。The deep geologic structures and typical tectonic patterns in the southeastern Hubei Province are analyzed by using regional seismic profile in combination with the result of surface geologic surveys, the differentiation in geologic structures between upper and lower strata are discussed. It is proposed that the “original geologic body” beneath Silurian detachment layer has the characteristics of relatively weaker deformation and wide-slow and open folds and it is protected by late extension and reconstruction in upside “foreign geologic body”, where is a benefitial area for hydrocarbon exploration.
