An interpretation of the deep structure of the Pieniny Klippen Belt in Poland is presented, utilizing a high-resolution deep seismic reflection survey. The studied profiles reach a depth of around 23 km. The seismic lines depict the structure and mutual relationships between the main domains analyzed—the Central Carpathians (CC), the Pieniny Klippen Belt (PKB) and the Outer Carpathians. The seismic lines show the Central Carpathian Paleogene (CCP) sediments covering the Tatric units and overlying Krížna and Choč nappes of the CC south of the PKB. The entire nappe pile comprising the CC units is thrust over sedimentary rocks that probably derived from the European Plate, representing a mixture of autochthonous platform Paleozoic to Neogene sediments and slices of Outer Carpathian and PKB rocks. The older crystalline basement of the European Plate is suspected to be below these sedimentary rocks. The reflections below 20 km depth show a possible boundary between different crustal elements within this plate. The PKB is part a of 3–5 km wide flower structure, limited by fault zones that include faults cutting across sediments of the CCP and the Magura Nappe. The fault marking the southern limit of the PKB is particularly well visible in the seismic sections. The Albian–Lower Miocene flysch sequences, constituting the main components of the PKB, form north-vergent thrust-sheets. During the Albian to Miocene the PKB originated as an accretionary prism in front of the moving CC Plate, followed by plate rotation and strike-slip processes. The entire CC nappe pile is thrust over the Precambrian and Lower Paleozoic crystalline basement of the European Plate and probably slices of the PKP. The Outer Carpathians display an allochthonous character above the European Plate and comprise several north-verging imbricated nappes (thrust-sheets). The European plate dips gently southwards below the PKB and the CC Plate, cut by several deep-reaching faults.

波兰Pieniny Klippen带的深层结构

利用高分辨率的深层地震反射调查，对波兰的Pieniny Klippen带的深层构造进行了解释。所研究的剖面深度约为23 km。地震线描述了所分析的主要区域（中央喀尔巴阡（CC），Pieniny Klippen带（PKB）和外部喀尔巴阡）之间的结构和相互关系。地震线表明，中喀尔巴阡古近纪（CCP）沉积物覆盖了塔克拉单位，并覆盖了PKB以南CC的Krížna和Choč尿布。包括CC单元的整个尿布桩都被推到可能源自欧洲板块的沉积岩上，代表了古生代至新近纪沉积物的自生平台台地以及喀尔巴阡外和PKB岩片。怀疑欧洲板块较旧的晶体基底位于这些沉积岩之下。20 km深度以下的反射表明该板块内不同地壳元素之间可能存在边界。PKB是3–5 km宽的花结构的一部分，受到断层带的限制，这些断层带包括跨CCP和Magura Nappe沉积物的断层。标记PKB南部极限的断层在地震剖面中尤为明显。构成PKB的主要组成部分的阿尔比－下中新世复飞序列形成了北缘的逆冲冲片。在Albian至中新世时期，PKB起源于移动CC板前的增生棱镜，随后是板旋转和走滑过程。整个CC推覆桩都被推到欧洲板块的前寒武纪和下古生代晶体基底之上，并且可能是PKP的薄片上。外部喀尔巴阡山脉在欧洲板块上方显示出异种特征，并由几个北缘的交叠式尿布（止冲片）组成。欧洲板块在PKB和CC板块的下方缓慢向南倾斜，被几个深部断层切断。
