大别-苏鲁造山带不同岩片(块)经历了不同的褶皱变形。榴辉岩块(或透镜体)和硬玉石英岩片经历了高压-超高压背景下的两幕褶皱变形之后,在区域性第一幕变形期间主要发生透镜化为主,后期与围岩共同经历紧闭同斜第二幕褶皱。而其它岩片主要经历了现今野外可见的区域性三幕褶皱,其中区域性第一幕褶皱为片内残留褶皱,在斜长角闪岩透镜体中多见,宏观规律不明。区域性第二幕褶皱在露头尺度多见,轴面为折劈理,局部强烈置换成片理化带(复合片理或第二期片理),恢复第三幕褶皱改造作用后,揭示出各种岩片中的各级尺度的第二幕褶皱都为轴面北西倾南东倒、轴迹走向为NNE向的紧闭不对称褶皱,不对称性一致反映其指向与各种岩片向南东的逆冲运动有关。第三幕褶皱为以片理或折劈理为变形面的宽缓褶皱,轴迹走向NWW,枢纽向西倾伏。韧性剪切带为非透入性构造,分早晚两期,早期为韧性逆冲,新县穹隆以南,运动学标志指示向北逆冲,错切第二幕褶皱,结合新县穹隆北部向南的逆冲特征,反映这些韧性逆冲断层多数为第二幕大型褶皱翼部的次级逆冲断层;晚期为韧性滑脱带,其发育局限于几个岩性差异较大的接触带,带内伸展型折劈理发育,并对挤压构造样式有重要的改造作用。华北克拉通东部地块是华北克拉通的重要组成,其盖层古生界和三叠系在印支运动期间经历了一幕宽缓褶皱作用,其轴迹方向主体也为NWW向。这一褶皱构造明显在变形时间、变形样式和展布方向上都和大别-苏鲁造山带中的第三幕褶皱非常一致,说明它们具有动力学上的必然联系。同时,研究表明在华北克拉通东部地块中没有经历大别-苏鲁造山带中区域性第一、第二幕褶皱变形的记录,故本文认为印支期这两幕变形主要发生在华北板块东南缘的边界上,并没有波及到板内,而且从东向西高压-超高压岩石剥露具有穿时性。只有当华北板块和华南板块在第二幕变形之后构成了统一块体后,第三幕变形才波及华北板内。 Dabie - Sulu orogenic rock fragments (blocks) experienced different fold deformation. The eclogitic blocks (or lens bodies) and the jadeite quartzites experienced two fold deformations under the background of high pressure-ultrahigh pressure. During the deformation of the first actural zone, the main lensing occurred. Closed syncline second act folds. However, the other rock fragments mainly experienced the regional three-fold folds that are visible in the field at present. The first regional folds are the residual folds in the field, which are more common in the amphibolite body and the macroscopic law is not clear. The regional second act folds are more common in the outcrops, the axial fold is cleft, and the local intense exchange is replaced by the physiochemical band (composite or second episode). After the restoration of fold modification in the third act, The second-scale folds at all levels in the lithofacies are all upside-down north-south-east axis with NNE-trending axisymmetric folds. The asymmetry reflects its orientation to the south-east Thrust movement related. In the third act, the folds are broad folds, which are treated or folded cleaved into deforming surfaces. The axles move toward the NWW, and the pivot points to the west. The ductile shear zone is of non-penetrating structure. In the early and late stages, the ductile shear zone is ductile in the early stage. The south of the new county is in the south, and the kinematic sign indicates northward thrusting. South of the thrust characteristics, reflecting the majority of these ductile thrust faults for the second act of the large fold wing of the secondary thrust; late ductile slip zone, its development is limited to several lithology with large contact zone, belt Within the extension of folding cleavage development, and extrusion structure has an important role in the transformation. The eastern part of the North China Craton is an important component of the North China Craton. Its cover Paleozoic and Triassic experienced a wide range of folds during the Indosinian movement, with NWW directions as their major axes. This fold structure is clearly consistent with the third fold in the Dabie-Sulu orogenic belt in terms of deformation time, deformation pattern and distribution direction, indicating that they have a kinetically inevitable connection. At the same time, the study shows that there is no record of the first and second episodes of fold deformation in the Dabie-Sulu orogenic belt in the eastern part of the North China Craton. Therefore, this paper argues that the two episodes of the Indosinian deformation mainly occurred in the North China Plate The southeastern margin of the border, and did not spread to the plate, and from east to west high pressure - high pressure rock with piercing time. Only when the North China plate and South China plate deformation in the second act after the formation of a unified block, the third deformation before the spread of North China board.
