Abstract

: The Pieniny Klippen Belt of the Western Carpathians is built up by Jurassic to Eocene Oravic units, with the Šariš, Subpieniny, and Pieniny Unit on the top. Major emphasis was placed on the dark fine-grained clastic deposits exposed in the vicinity of the villages of Beňova Lehota and Revišné (Orava sector of the Pieniny Klippen Belt). Through investigation of palynological material, the age of dark flysch strata was determined as predominantly uppermost Toarcian to Middle Aalenian and affiliated with the Szlachtowa and/or Skrzypny formations, belonging to the Šariš Unit. The results from the dinoflagellate cysts were supplemented by a structural investigation of the Šariš Unit. The complicated tectonic evolution of the Pieniny Klippen Belt is documented by intermixing of the soft shale deposits of Jurassic and Cretaceous age and by the presence of folds and cleavages. Based on the acquired data, the D 1 event records a compression with a NE–SW direction and is represented by folds with axial-plane cleavage. The younger D 2 phase is marked by the presence of south-vergent backthrusts, resulting from the ongoing compression and subsequent tilting of the originally north-vergent nappe stack of the Oravic units.

pinenini - Klippen带Orava段:基于有机壁鞭毛藻囊的岩性、构造与地层学(Šariš Unit)

：西喀尔巴阡山脉的Pienin-Klippen带由侏罗纪至始新世的Oravic单元建造，顶部为Šariš、Subpienny和Pieniny单元。重点放在Beńova Lehota和Revišné村（Pieniny Klippen带的Orava区）附近暴露的深色细粒碎屑矿床上。通过对孢粉材料的调查，确定了深色复理石地层的年龄主要为托阿尔阶至中阿勒阶的最上层，并隶属于Szlachtowa和/或Skrzypny地层，属于Šariš单元。对Šariš单元的结构调查补充了甲藻囊肿的结果。侏罗纪和白垩纪软页岩矿床的混合以及褶皱和解理的存在，记录了Pienin-Klippen带复杂的构造演化。根据获得的数据，D1事件记录了NE–SW方向的压缩，并由具有轴向平面解理的褶皱表示。较年轻的D2期的特征是存在南向逆冲，这是由于Oravic单元的原始北向推覆岩堆的持续挤压和随后的倾斜造成的。

期刊介绍： GEOLOGICA CARPATHICA covers a wide spectrum of geological disciplines including geodynamics, tectonics and structural geology, volcanology, stratigraphy, geochronology and isotopic geology, karstology, geochemistry, mineralogy, petrology, lithology and sedimentology, paleogeography, paleoecology, paleobiology and paleontology, paleomagnetism, magnetostratigraphy and other branches of applied geophysics, economic and environmental geology, experimental and theoretical geoscientific studies. Geologica Carpathica , with its 60 year old tradition, presents high-quality research papers devoted to all aspects not only of the Alpine-Carpathian-Balkanian geoscience but also with adjacent regions originated from the Mediterranean Tethys and its continental foreland. Geologica Carpathica is an Official Journal of the Carpathian-Balkan Geological Association.
