As a result of the rescue excavation at 11 Vídeňská Street in 2021, we can specify the extension of a previously excavated area in the cadastral territory of Štýřice. A small collection of chipped stone industry and animal bones was unearthed. The form of these finds, their stratigraphic position, and a radiocarbon date retrieved from one of the an...
Article
In the multi-level quarry Předklášteří near Tišnov exploiting medium-grained biotite metagranite of the Brunovistulicum, up to 30 m thick unconsolidated sediments, were studied recently at the top of excavation. These sediments are exposed at the two top quarry levels. During the exploration work in 1965, these sediments were not encountered, becau...
Article
Only a few loess–palaeosol sequences from the last climatic cycle (Eemian-Weichselian) in East-Central Europe have been studied and correlated with up-to-date stratigraphic frameworks such as marine isotope stages (MIS) and Greenland Stadials/Interstadials (GS/GI). This paper examines the relations of local conditions and climatic trends to soil de...

In 2018 an excavation of 20 × 20 m large and up to 5 m thick calcareous clays of the Langhian age was found. Rich and diversified assemblages of foraminifers with species Orbulina suturalis Brön. and Martinotiella karreri (Cush.) indicate early Badenian (in sense of the Central Paratethys regional stratigraphy) age of the sediments, zone M5b sensu...
Article
The Langhian epicontinental sea - the Central Paratethys - represented a dynamic environment experiencing many changes, making it an ideal system for testing various geochemical proxies. Here we present a result of a study based on a combination of organic geochemistry (δ13Corg, n-alkane based indices; TOC/TIC) with benthic foraminiferal stable iso...
Article
Full-text available
Sedimentological study on the Northern bailey of the fortified site Pohansko allows identification of 9th lithofacies and 2 facies associations. The lower facies association is interpreted as an infill of fluvial channels (mostly mid-channel dunes) with two cycles of filling. The fluvial channels were relatively shallow and broad (high width/depth...

The site is situated in the bottomland near the confluence of Dyje and Morava rivers. The junction area is split by many sides and inactive channels. The human impact (settlement establishment, deforestation and landscape management) is also reflected in the bottomland development. Processes lead to erosion, accumulation of sediments in river beds...

In 2015 the locality Borač-Podolí was newly examined. The locality is situated 8 km NW from the town of Tišnov. A large amount of shallow-water fossils of middle Miocene (Badenian) age was collected. The state of preservation of the material enabled us bivalve borings of ichnogenus Gastrochaenolites which were bored into colonies of hermatype coral...

Dagmar Cave, Czech Republic, is the first locality in the Moravian Karst where sediments of Cromerian age have been discovered and it is the first locality with such a large number of species of molluscs of this age. It was originally a swallow hole initiated in the Neogene, which has since accumulated sediments. Basal sediments are palaeontologica...

Article
Records of occupation by humans in the period following shortly after the Last Glacial Maximum (LGM; 21 ± 2 kyr cal. BP) are still very rare in Central Europe, since it is inferred that the extreme climatic conditions caused the decolonisation of previously settled areas. Our study focuses on the reconstruction of environmental conditions in the su...

Colonization by marine organisms such as foraminifers, molluscs, bryozoans, brachiopods and red algae during the middle Miocene (early Badenian) transgression near Přemyslovice (Carpathian Foredeep) was initially affected by a cool water current of unclear origin. However, shortly afterwards, fallout of volcanic material caused a total termination...

Fifty-two ostracod taxa were identified from two sediment cores collected from the early Badenian Židlochovice stratotype. Ostracod assemblages were analyzed with a focus on taxonomy, paleoecology, distribution of taxa along the sediment cores, quantification of valve/carapace ratios, and species richness by Simpson’s Reciprocal Index. The changes...

During Late Miocene, the Western Carpathian paleogeography started to change. The Lake Pannon retreated southwards, and the northern coast of the back arc basin was slightly elevated due to progradation of deltaic and alluvial facies, especially in the lowlands. The studied „Pannonian lake" sediments come from the Czech and Slovak parts of Central...

Geologically, the Cenozoic represents the period when Africa and Europe were converging, with seafloor spreading taking place in the Atlantic only as far north as the Labrador Sea (between Greenland and North America). Additionally, numerous microplates in the Mediterranean area were compressed as a direct result of Africa-Europe convergence, gradu...

Reworked palynomorphs occur in the cave sediments of the Moravian karstic areas as well as in marine sediments of the Carpathian Foredeep (Czech Republic). Their preservation states may be different or similar under the light microscope. The mutual distinguishing features of primarily Quaternary and Tertiary ones, or of the palynomorphs from partic...

The sediments from the southern part of the Carpathian Foredeep in Moravia (Czech Republic) and the Modrý Kamen basin from Slovakia were studied. The sediments are of Eggenburgian to Lower Badenian ages and of marine or brackish origin. The marine facies rapidly changes with lagoonal and deltaic facies during the Eggenburgian-Ottnangian. The palyno...

Project
NECLIME is an open international network of scientists working on Cenozoic climate evolution and related changes of continental ecosystems. During the past 65 million years of Earth history, globally warmer-then-present conditions prevailed in a world with almost modern paleogeography. These timespans represent promising case studies for anticipated future scenarios. Within the NECLIME network, we aim to combine data on past climate change and its environmental impact for large-scale reconstructions. NECLIME research activities comprise paleoclimate reconstructions, including atmospheric CO₂ and ecosystem analysis using multiple quantitative methods on various primarily continental proxies (plants; vertebrates; invertebrates; geochemistry and geological proxies). Complementing model studies are employed to assess connections and processes driving ocean, atmosphere and biosphere at global and regional scales. NECLIME was established in 1999 with the aim to understand Neogene trends across Eurasia. This basic idea quickly and constantly expanded to a global interest and a wider stratigaphical frame. The steadily growing NECLIME network with currently around 140 members in 34 countries is coordinated by a team of researchers and an advisory board. NECLIME holds annual conferences and workshops and administers working groups bringing forward scientific exchange, joint projects, and the integration of research data.
