摘要

本文的目的是研究波兰南部Pieniny mms地区Pieniny Klippen带岩石杂岩体的断裂和褶皱及古应力场重建。采用野外地质构造研究方法,包括运动学方法和利用Win-Tensor程序重建古应力场。结果。在多瑙河右岸Szczawnytsia市(波兰南部)的西南郊区,在PKB的大型无根地块中研究了许多褶皱和断层变形,它们的运动学类型和结构模式。恢复了逆冲型、正向型和走滑运动学型古应力场。逆应力场中,在强、弱岩体边界上形成逆冲构造。下部块体韧性较强的岩石中形成了药褶带、杂褶带和破碎地层带。在正应力场中,前逆冲断层被正断层激活,并被正交和斜左旋走滑断层切割。逆冲断层运动形态转变为带左旋走滑成分的斜向正断层,在活动断层的边缘地带形成拖折褶皱和s型褶皱。在最年轻的应力场中,前逆冲面被激活为走滑面。沿限制推力的正交面和斜面也记录了剪切变形。研究了无根地块不同部位构造变形和褶皱构造的运动类型,揭示了断翼在水平和垂直平面上的旋转。无根块体运动表面的波浪形可能是其各节段同时存在压缩和张力场的原因。科学的新奇。研究结果确定了各古应力场中断裂的运动类型、相互关系及发育特征。建立了逆冲构造及其断层的构造特征、褶皱变形与断裂变形的关系。建立了断层运动类型从逆运动到走滑运动的时间变化规律。实际的影响。所获得的结果补充了Pieniny Klippen带的形成历史,可用于改进构造图和选择该地区的地球动力学模型。关键词:皮宁-克利彭带;古应力;逆冲;

TECTONIC DEFORMATIONS AND PALEOSTRESS FIELDS IN THE ROCK COMPLEXES OF THE PIENINY KLIPPEN BELT IN THE CITY OF SZAWNYCTA (POLAND)
Purpose of the paper is study of faults and folds and reconstruction of paleostress fields in rock complexes of the Pieniny Klippen Belt in Pieniny Mts. area (Southern Poland). Methods of field geological and structural research were involved, including the kinematic method with subsequent reconstruction of paleostress fields using the program Win-Tensor. The results. On the right bank of the Danube River in the south-western outskirts of the city of Szczawnytsia (Southern Poland), numerous fold and fault deformations, their kinematic types and structural patterns were studied in the large rootless block of the PKB. Paleostress fields of the thrust, normal and strike-slip kinematic types have been restored. In the inverse stress field, thrusts were formed on the border of competent and incompetent rocks. Drug-folds, mélange and broken formations zones were formed in the more ductile rocks of the lower block. In the normal-type stress field, the former thrusts were activated as normal faults and cuted by the ortogonal and oblique sinistral strike-slip faults. The kinematic sence of the thrusts changed to an oblique normal faults with a component of the sinistral strike-slip, in the bodering zones of the activated faults, drag folds ans s-type folds were formed. In the youngest stress field, the former thrust surfaces were activated as strike-slip ones. Shear deformations were also recorded along thrust-limiting orthogonal and oblique surfaces. Kinematic types of tectonic deformation and folded structures in the different parts of the studed rootless block vitnesses the rotation of the fault wings in the horizontal and vertical planes. The wavy shape of the surface of the movement of the rootless block may be the reason for the simultaneous existence of a field of compression and tension in its various segments. Scientific novelty. As a result of the research, the kinematic types of fault, their relationships and features of development in various paleostress fields were determined. The features of the structure of the thrust and the faults that cut them, the relationships of folded and faulted deformation are established. Changes of the kinematic types of faults in time from the inverse to the strike-slip type have been established. Practical impact. The obtained results complement the history of the formation of the Pieniny Klippen Belt and can be used to refine tectonic maps and select a geodynamic model of the region. Key words: Pieniny Klippen Belt, paleostress, thrust, strike-slip, mélange.
