<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">The depositional conditions of kame terraces in a mountain valley were analysed sedimentologically and petrologically through a series of kame terraces in the Rudawy Janowickie mountains. The kame terraces comprise five lithofacies associations. Lithofacies association GRt, Sp originates from deposition in the high-energy, deep gravel-bed channel of a braided river. Lithofacies association GC represents a washed out glacial till. Probably a thin layer of till was washed out by sandy braided rivers (Sp). The fourth association (Fh, Fm) indicates a shallow and quite small glaciomarginal lake. The last association (GRt, GRp) indicates the return of deposition in a sandy-bed braided channel. The petrography of the Janowice Wiekie pit and measurements of cross-stratified beds indicate a palaeocurrent direction from N to S. The Janowice Wielkie sedimentary succession accumulated most probably during the Saalian (Odranian, Saale I, Drenthe) as the first phase of ice-sheet melting, because the kame terrace under study is the highest one, 25-27 m above the Bóbr river level. The deposits under study are dominated by local components. The proglacial streams flowed along the margin of the ice sheet and deposited the kame terrace. The majority of the sedimentary succession was deposited in a confined braided-river system in quite deep channels.</abstract>

Sedimentation style of a Pleistocene kame terrace from the Western Sudety Mountains, S Poland

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">An atypical lithological development of outwash deposits in the Carpathians Foreland (S Poland) shows lower and middle parts of the sedimentary succession that are characterized by sinuous palaeochannels. This channel facies consists of laterally accreted sands derived from side bars. The sedimentary environment was a proglacial system of anabranching channels, presumably of anastomosed type. The outwash channel pattern was most probably controlled by the raising base level of the fluvial system. Both proglacial and extraglacial waters were dammed by a sandur within a small upland valley. Aggradation and progradation of the glaciofluvial deposits resulted in progressive rising of the dammed lake level. The low hydraulic gradient of the outwash streams resulted in a sinuous planform as well as a low-energy style of deposition. Afterwards, the rising lake water was drained off through a low watershed and the entire valley became filled with outwash sediments. The bedrock morphology thus became buried and a typical unconfined sandur with a braided channel network developed during the last phase of the glaciomarginal sedimentation (upper part of the sedimentary succession under study).</abstract>

Geologos

GEOLOGOS is an international, peer-reviewed journal publishing research results and review articles covering all earth-science disciplines, with a focus on the geology of central and eastern Europe. Studies on areas of poorly known geology (e.g. Asia and Africa) are also published. Articles from non-European areas should be universal and problem-related, while purely regional issues are avoided.  Over the last years, Geologos has published studies on many topics, including:    mineralogy and geochemistry  sedimentology (siliciclastics and carbonates, sedimentary structures, facies analysis)  palaeontology (invertebrate palaeontology, trace fossils, micropalaeontology)  stratigraphy and petroleum geology (sequence stratigraphy)  glacial geology (Pleistocene palaeogeography and stratigraphy, lithology of glaciogenic deposits)  hydrogeology (groundwater circulation, groundwater flow models, drainage systems, deep aquifers)  meteorites (Morasko meteorite fall).    GEOLOGOS has been issued since 1995 as the journal of the Institute of Geology, Adam Mickiewicz University (AMU) in Poznań, Poland.  GEOLOGOS is an open access journal; all content is freely available without charge.  Three issues of GEOLOGOS are published each year. Electronic versions of all papers are published on the Sciendo platform.  Why subscribe and read    Journal on geology of Central and Eastern Europe as well as other areas of poorly known geology   Why submit    Quick publication, colour pages free of chargé. To publish in GEOLOGOS, authors are not required to pay an Article Processing Charge.   Reviewing    Each manuscript, as a rule, is reviewed by two referees, commonly one Polish and one foreign. Reviews are double-blind.   Rejection Rate    About 40%    Archiving  Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.  Plagiarism Policy  The editorial board is participating in a growing community of Similarity Check System's users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.
