中文摘要: 利用Morley 等的调节构造理论和构造几何学分析,借助地质构造图、断层垂直位移分析等,在冀中坳陷识别出5 种调节带类型和7 种调节带构造形式,进而探讨了它们各自出现的特定构造部位、调节作用、主要构造特点和典型实例。同向趋近型调节带呈现鼻状、地垒状和转换断层3 种构造形式,在断层段连接处以鼻状构造形式出现,而在控凹断层连接处则以转换断层与横向凸起并存的形式出现;同向叠覆型调节带以走向斜坡形式调节应变; 同向平行型调节带以翘曲的形式改造河西务潜山带。对向平行型调节带以低凸起的形式发育于雁翎地区; 对向趋近型调节带以鄚州枢纽带为典型,受两期应变的调节形成了底部以断层分叉斜滑与上部呈宽阔翘弯带的双层变形系统。产生调节作用的断层在地质演化过程中活动强度均呈现此起彼伏、此消彼长的构造特征。受调节带的影响与改造,在潜山断坡上可形成以古构造脊为优势运移通道的油气运移路径。
Abstract:According to the accommodation structure theory,in combination with the analysis on geological map and paleo-fall, five accommodation zones and seven structure forms have be recognized in Jizhong Depression.The synthetic approaching-type accommodation zone can occur as nose structure,horst and transform fault,e.g.,it occurs as nose structure exist in fault segment joints,but as coexistence of transform fault and transverse salient in the joints of faults controlling depression.The synthetic overlap-type accommodation zone transfers strain in the form of trend slope.The synthetic collateral-type accommodation zone reforms the Hexiwu buried hill belt in the form of warping.The convergent collateral-type accommodation zone develops in Yanling area in the form of low uplift.The convergent approaching-type accommodation zone,typically observed in the Maozhou hub zone,forms double-layer deformation system,which comprises a bottom of fault bifurcation oblique slip and an upper of wide cup zone.In the geological evolution,a relation of ebb and flow can be obserbed among the activity intensities of the faults which play the part of accommodation.With the effect and reformation of accommodation zone,a migration path for oil and gas,with ancient structural ridge as dominant migration pathway,can be formed on the slop of buried hill.
