This paper presents the results of geophysical survey performed in the Pilawa River valley in the area of Middle Pomerania (Poland). The resistivity imaging method was applied. Resistivity profile measuring eight hundred metres allowed to investigate the geologic structure to the depth of 150 metres. The resistivity cross section shows the structure of Pleistocene sediments and the depth of Miocene - Pleistocene boundary. The significant lowering of the boundary is related to assumable ice-sheet margin range of Pomeranian phase of North Polish Glaciation. The lowering of the boundary may be a result of sediments compaction and the subglacial tunnel slope as well., Bogdan Żogała, Ryszard Dubiel, Józef Lewandowski, Waclaw M.

Fluvial archives of the Polish Carpathians bear a record of both climatic and tectonic signatures. The former consist in cyclic development of terrace covers interfingering with and/or overlain by soliluction and slopewash sediments; the latter include disturbances within strath long profiles and differentiated size of erosional downcutting. Valleys of the Outer Carpathians bear five to nine terrace steps of Pleistocene age. Most of these terraces are strath or complex-response ones; the Weichselian and Holocene steps are usually cut-and-fill landforms, except those located in the neotectonically elevated structures characterized by the presence of young straths. Long profiles of individual strath terraces frequently show divergence, convergence, upwarping, downwarping, or faulting that can be indicative of young tectonic control. Moreover, the size and rate of dissection of straths of comparable age are different in different morphotectonic units; a feature pointing to variable pattern of Quaternary uplift. Rates of river downcutting result mainly from climatic changes throughout the glacialinterglacial cycles, but their spatial differentiation appears to be influenced by tectonic factors as well. Examples based on detailed examination of deformed straths and fluvial covers in selected segments of the Polish Carpathian rivers appear to indicate Quaternary reactivation of both normal and thrust bedrock faults. The latter are mostly confined to the eastern portion of the Outer Carpathians. The Early Pleistocene, Holsteinian and Eemian stages of reactivated faulting dominated throughout the study area., Witold Zuchiewicz., and Obsahuje bibliografii
V průběhu neogénu byli s výjimkou jihoamerických vačnatých thylakosmilidů po celém světě jedinými představiteli šavlozubého ekomorfotypu již pouze šelmy barbourofelidi (Barbourofelidae) a příslušníci čeledi kočkovitých (Felidae). Někteří z nich pak dosahovali značné velikosti a mimořádně robustní stavby těla, přičemž v těchto ohledech překonávali ty největší zástupce dnešních velkých koček. Zvláště šavlozubé kočky na dlouhou dobu obsadily pozici na vrcholu potravní pyramidy, než nakonec definitivně vymizely ke konci pleistocénu ze Severní a Jižní Ameriky. Ve Starém světě však vyhynuly již o něco dříve během čtvrtohor, zřejmě následkem zesílené vzájemné konkurence s velkými kočkami, především pak se lvy a tygry., During the Neogene, with the exception of thylacosmilids, barbourofelids and felids were the only representatives of the sabre--tooth ecomorphotype worldwide. Some of them attained tremendous size and were of very robust somatic constitution, exceeding in these aspects the largest contemporary cats. Especially the sabre-tooth felids occupied the top of the trophic chain for a long time before their demise at the end of the Pleistocene in both North and South America. But in the Old World these predators disappeared somewhat earlier, probably due to the strength of mutual competition with other large felids, namely the lions and tigers., and Stanislav Knor.
