Kurzfassung Ordovizische Sedimente und Magmatite in variierenden Metamorphose-und Deformationsstadien sind ein Hauptbestandteil des mitteleuropäischen Variszikums. Das Ordovizium Thüringens liegt in einer mehr als 3000 m mächtigen klastischen Abfolge vor, die typisch für den Nordrand Gondwanas ist. Die grundlegende Gliederung der Schichtenfolge läs...
Kurzfassung Der Walpernhainer Ton ist eine Sonderausbildung in der Volpriehausen-Formation im Nordosten der Thüringer Mulde. Er besteht aus drei mehrere Meter mächtigen Tonhorizonten (1-3), die von zwei Sandsteinen getrennt werden. Lithostratigraphisch wird der Walpernhainer Ton in die Rot-weiße Wechselfolge der Volpriehausen-Formation gestellt. Di...
Following the end-Permian crisis, microbialites were ubiquitous worldwide. For instance, Triassic deposits in the Germanic Basin provide a rich record of stromatolites as well as of microbe-metazoan build-ups with nonspicular demosponges. Despite their palaeoecological significance, however, all of these microbialites have only rarely been studied....
Die magnetische Suszeptibilität von rezenten fluviatilen Sedimenten im Saale Einzugsgebiet wird mit derjenigen potentieller Liefergesteine verglichen. Liefergesteine mit hoher Suszeptibilität sind vor allem paläozoische Basaltoide und ihre metamorphen Produkte sowie stratiforme und gangförmige Vererzungen in Schiefergebirgsarealen. Dabei zeigt sich...
Past orbital parameters of the Moon are difficult to reconstruct from geological records because relevant data sets of tidal strata are scarce or incomplete. The sole Archean data point is from the Moodies Group (ca 3.22 Ga) of the Barberton Greenstone Belt, South Africa. From the time‐series analysis of tidal bundles from a well‐exposed subaqueous...
Upper Turonian to lower Coniacian marls of the Strehlen Formation of the Graupa 60/1 core were investigated for their foraminiferal content to add stratigraphical and palaeoenvironmental information about the transitional facies zone of the Saxonian Cretaceous Basin. Further comparison with foraminiferal faunas of the Brausnitzbach Marl (Schrammste...
Temporal evolution of element ratios in the catchment of the River Thuringian Saale
A literature retrieval was performed for a total of about 5491 datasets of whole rock geochemical analyses of sedimentary, magmatic and metamorphic rocks in the catchment of River Thuringian Saale for the past 600 Ma. Considering availability and coincidence with p...
We present a geological field guidebook where important and actual outcrops of the Lower Buntsandstein (Lower Triassic) in Central Germany are documented. It is mainly written for geoscientists interested in sedimentary geology. The field guide documents the sedimentary succession of the Lower Buntsandstein Subgroup (Calvörde and Bernburg formation...
The aftermath of the Permian – Triassic crisis is characterized by ubiquitous occurrences of microbial sediments around the world. For instance, Triassic deposits of the Germanic Basin have shown to provide a rich record of stromatolites as well as of microbe-metazoan build-ups with non-spicular demosponges. Despite their paleoecological significan...
Central and western Europe were affected by a compressional
tectonic event in the Late Cretaceous, caused by the convergence of Iberia
and Europe. Basement uplifts, inverted graben structures, and newly formed
marginal troughs are the main expressions of crustal shortening. Although
the maximum activity occurred during a short period of time betwee...
The ca. 35 km long, N-S-trending Altyn Darya valley in Kyrgyzstan exposes a nearly complete cross-section of the External Pamir thrust belt (EP), extending from the active Pamir Frontal Thrust in the north to the Main Pamir Thrust (MPT) and some distance into its hanging-wall. The EP comprises a northward imbricated stack of Carboniferous to Late N...
Der stratigraphische Begriff Muschelkalk wurde 1761 von Georg Christian Füchsel in Thüringen geprägt. In der Thüringer Mulde liegt das Typusgebiet des Muschelkalks, außerdem das Typusprofil der Jena-Formation. Der 100–110 m mächtige Untere Muschelkalk wird ganz von der Jena-Formation gebildet und ist in die klassischen Bankfolgen Oolithbank-, Tereb...
Die Unterer-Muschelkalk-Subgruppe (vereinfacht: Unterer Muschelkalk) wird nach Lithologie, Abgrenzung zum Liegenden und Hangenden, Mächtigkeit, geographischer Verbreitung, Biostratigraphie, Leitflächen, Alter, Paläoökologie beschrieben. Aufgeführt werden auch Synonyme, Typgebiet und wirtschaftliche Verwendung. Die Subgruppe umfasst marine Karbonate...
Central Europe was affected by a compressional tectonic event in the Late Cretaceous, caused by the convergence of Iberia and Europe. Basement uplifts, inverted graben structures and newly formed marginal troughs are the main expressions of crustal shortening. Although the maximum activity occurred in a short period between 90 and 75 Ma, the exact...

Die Bohrung Siegmundsburg wurde direkt neben einem auflässigen und heute verfüllten Steinbruch bei Siegmundsburg abgeteuft, in dem die ältesten Körperfossilien des Thüringer Ordoviziums nachgewiesen wurden. Die inarticulaten Brachiopoden der Art Hyperobulus feistmanteli fanden sich in Quarziten, die dem Oberen Frauenbachquarzit zugerechnet wurden....
The continental expression of global cooling during the Miocene Climate Transition in Central Asia is poorly documented, as the tectonically active setting complicates the correlation of Neogene regional and global climatic developments. This study presents new geochemical data (CaSO4 content, carbonate δ¹³C and δ¹⁸O) from the endorheic alluvial‐la...
This study illustrates how decoupling of quartz and zircon can be used advantageously in provenance research. Thirty‐eight fine‐grained to coarse‐grained arkose samples of the Early Triassic intracontinental Buntsandstein Group from the Central European Basin in Germany were analysed for their petrography and 1200 grains in 23 of these for their de...
Central Asia witnessed progressive aridification during the Miocene, commonly related to mountain uplift, the Paratethys retreat and global climate cooling. However, the formation of Miocene lakes in Central Asia seems to oppose drier conditions suggesting that the precise timing, extent and forcing of the aridification is still not well‐constraine...
The study area is located in the central German platform a prominent structure of which is the Lichtenau Graben. The graben has a strike of c. N030 and continues towards the north into the similarly oriented Leinetal Graben. At their junction, both grabens interfere with the NW‑SE‑striking Eichenberg‑Gotha‑Saalfeld fault zone of the Thuringian Basi...
This study stresses how zircon-grain length versus age correlation significantly can improve provenance interpretations. Hence, taking sedimentary sorting effects into account, we present a detrital-zircon provenance study for continental deposits of the Central European, Lower Triassic Buntsandstein Group in Germany. The Buntsandstein Group was de...
The Saxonian–Bohemian Cretaceous Basin (Elbsandsteingebirge, E Germany and Czech Republic, Elbtal Group) comprises Upper Cretaceous sedimentary rocks from Upper Cenomanian to Santonian age. These sandstones were deposited in a narrow strait of the sea linking the northern Boreal shelf to the southern Tethyan areas. They were situated between the We...
The continental settings of Central Asia witnessed increased desertification during the Cenozoic as a result of mountain uplift and the Paratethys retreat. The interaction of these tectonic-scale processes with orbitally-forced climate change and their influence on Asia's atmospheric moisture distribution are poorly constrained. A Miocene successio...
Enhanced aridification of Central Asia driven by the combined effects of orogenic surface uplift, Paratethys retreat, changes in atmospheric moisture transport and global cooling is one of the most prominent Cenozoic climate change events of the Northern Hemisphere. Deciphering regional long-term patterns of Central Asian hydrology is, therefore, a...

Die Region des Südharzes im Bereich der Sangerhäuser Mulde ist bekannt für ihren langjährigen Kupferschieferabbau. Aufgrund der Hebung des Harzes während der Oberkreide wurden auch die permischen Ablagerungen am Südrand gehoben und streichen heute flach an der Oberfläche aus. Die Kleinhalden prägen das Landschaftsbild nahe des Kupferschiefer-Ausstr...
The NE Tajik Basin in Central Asia, compressed between the ranges of the Tien Shan in the north and the Pamir in the south, is a key region for understanding the evolution of these mountain systems. Erosion and deposition history of the NE Tajik Basin and the adjoining orogens since the late Oligocene is reflected in the sedimentary record.
The sed...

The post-Variscan thermal history of the Erzgebirge (Germany) is the result of periods of
sedimentary burial, exhumation and superimposed hydrothermal activity. The timing and degree of
thermal overprint have been analysed by zircon and apatite (U-Th)/He and apatite fission track
thermochronology. The present-day surface of the Erzgebirge was exhum...
Sandstones of the Triassic Buntsandstein in central Germany were analysed to reveal the influence of facies and diagenesis on pore space evolution and petrophysical properties. The Thuringian Buntsandstein records fluvial, sandflat, lacustrine and aeolian environments. Petrophysical data imply a strong control of facies on porosity and permeability...
The Thuringian Syncline is a shallow synform of mainly Triassic strata in Central Germany. In general, its lithostratigraphic units are similar to that of the North German Basin. On the top of the Paleozoic basement and Permocarboniferous red beds the evaporites of the late Permian Zechstein were deposited. The Triassic super group consists of fluv...
The Ili basin is an intercontinental basin framed in the north by the Jungar Alatau mountains and in the south by the North Tien Shan mountains. Its development is linked to orogenic processes occurring in the region as a consequence of India-Asia collision.
Cenozoic continental clastic sedimentary rocks fill the syntectonic basin, unconformably...
Im Sommer 2013 wurde im Norden Erfurts die Forschungsbohrung EF-FB 1/12 im Rahmen des BMBF-geförderten Projektes INFLUINS niedergebracht. Die Tiefbohrung durchteufte die quartäre Überdeckung, sowie die darunter liegende triassische Gesteinsabfolge in der zentralen Thüringer Mulde vom Mittleren Keuper bis kurz vor die Buntsandstein-Zechstein Grenze...
The northern front of the Cenozoic Tien Shan mountains in Kazakhstan comprises east to
NE-trending thrust-related basement uplifts. Some of these are open, asymmetric anticlines, whereas others are fault-bounded blocks. Where emergent and exposed, the bounding faults dip steeply at 45–708. Large-wavelength open folds in the Cenozoic cover also over...
The Thuringian Syncline is a regional syncline in central Germany. Its stratigraphy is similar to that of the North German Basin from the Permian to Triassic times. The recent structural configuration of the Thuringian Syncline is characterized by a number of northwest trending fault zones, which are mostly extensional with only small displacements...
Mesozoic sediments in Saxony are represented by few limited occurrences of Lower Triassic and Middle to Upper Jurassic deposits but mainly by Upper Cretaceous predominantly clastic units filling the Elbe Zone (Pietzsch 1963, Voigt & Tröger in Niebuhr et al. 2007, Tröger in Pälchen & Walter 2008). The latter ones are confined by the Lausitz Block (p...
The northern front of the Cenozoic Tien Shan mountains in Kazakhstan comprises east- to NE-trending thrust-related basement uplifts. Some of these are open, asymmetric anticlines,
whereas others are fault-bounded blocks. Where emergent and exposed, the bounding faults dip steeply at 45–70°. Large-wavelength open folds in the Cenozoic cover also ov...
The Elbe Zone at the northern Bohemian Massif (part of the Central
European Variscides, Saxony, Germany) contains important structures and
outcrops that help to understand the final pulse of the Variscan Orogeny
in Europe leading to the formation of supercontinent Pangea. We will
present zircon U-Pb data from that area that allow the timing of the...

Continental climate dynamics prior to uplift of the Northern Tien Shan -
the Oligocene-Miocene succession of the Ili Basin, southeastern
Kazakhstan
The Cenozoic Tien Shan and Junggar Alatau mountains developed on the
southern part of the Paleozoic Altaid orogen as a far-field effect of
the collision of the Indian and Eurasian plates. Highland terrain,
active seismicity, and fast GPS-derived motions are evidence of rapid
ongoing mountain growth today. Variations in relief energy,
hight-to-width...
The Thuringian Basin in Central Germany is a structural trough with
Buntsandstein and Zechstein outcropping at the margins and Keuper
sedimentary fill in the center. Major aquifer units are Permosilesian,
Lower and Middle Buntsandstein and Keuper clastics. In this study we
compare aquifer characteristics of the Permosilesian and Buntsandstein
sedim...
This study is part of a collaborative research project examining the
basin wide movement of fluids in the subsurface (INFLUINS - integrated
fluid dynamics in sediment basins). The Lower Triassic Buntsandstein is
a major aquifer in Thuringia and adjacent areas in central Germany. The
sediments exhibit an overall trend of base level and associated
en...
The northern front of the Tien Shan mountains in Kazakhstan comprises an
array of thrust-related basement uplifts of varying size and
orientation. Many of these uplifts are asymmetric anticlines with long,
gently dipping backlimbs, rounded hinges and more steeply dipping, short
frontlimbs, suggesting they may overlie listric thrust faults. Where
ex...

В регионе наблюдаются сбросы смещающие пласты до санташской серии (плиоцен), надвиги пересекают более молодые отложения иногда наследуя поверхность сбр...
The Tien Shan active intraplate orogen of Central Asia exhibits strong along-strike variations in structure. Its northern front in southeastern Kazakhstan is characterized by a fragmented array of anticlinal basement highs whose wavelengths range from c. 5 to 30 km. Range-bounding faults are mostly E- to ENE-trending thrust or reverse faults and SE...
During the Late Cretaceous to Early Tertiary some parts of the Central European Basin System (CEBS) were uplifted along NW-SE to WNW-ESE striking compressive fault systems. As a result Pre-Zechstein (Permian) basement is exposed at the southern border of the CEBS from Central Germany to the sudetes still further east (e.g. Harz Mountains, Thuringia...
