“…The interval between 0. 4 Ma (lower limit of U/Pb dating) and the time covered by radiocarbon data provided by Zöller et al (2007) and Dill et al (2020a) [62,68] is not covered by absolute age data but based only on lithostratigraphic correlation of terraces and a more precise chronological assignment cannot be given here.…”

“…Stable drainage systems with a fairly high sinuosity degree of S > 2.5 occurred at the beginning but they developed into a metastable type with sinuosity degrees approximating S = 1; farther downstream they end up in the foreland in an ultrastable drainage systems as the S values reach values of as much as 11 at very low gradient (Tables 2 and 5) [62]. Such abnormally high values are indicative of the marginal facies of a fluvial-lacustrine environment.…”

“…An amendment has been made based upon the datasets obtained from our previous studies of the proximal foreland rivers enabling us to subject the different streams to a more subtle subdivision and genetic interpretation. This newly introduced classification scheme can be applied to the basin-and-range topography in a sedimentary foreland and the upstream basement, alike (Figures 8-10, Table 2): Straight: <1.1, low-sinuosity: 1.1 to 1.3, high-sinuosity: 1.3 to 1.5, moderately meandering: 1.5 to 2.0, strongly meandering: 2 to 5, very strongly meandering with sedimentary trap sites > 5 [62]. According to this classification scheme the majority of channel systems under examination plot into the pigeonhole low-sinuosity, a channel type mostly found in the TA of the study areas (Table 2).…”

The gravel is subjected to a visual morphological examination while subdivided into six classes of roundness from very angular to well-rounded according to Illenberger (1991) [60] and discriminated granulometrically using the suggestions put forward by Pettijohn et al (1987) [118].…”

Straight to Low-Sinuosity Drainage Systems in a Variscan-Type Orogen—Constraints from Tectonics, Lithology and Climate

A holistic-modular approach has been taken to study the evolution of three straight to low-sinuosity drainage systems (=SSS) in an uplifted basement block of the Central European Variscides. The development of the SSS is described by means of a quadripartite model. (1) The geological framework of the SSS: Forming the lithological and structural features in the bedrock as a result of different temperature, pressure and dynamic-metamorphic processes. (2) Prestage of SSS: Forming the paleo-landscape with a stable fluvial regime as a starting point for the SSS. (3) Proto-SSS: Transition into the metastable fluvial regime of the SSS. (4) Modern SSS: Operation of the metastable fluvial regime Tectonics plays a dual role. Late Paleozoic fold tectonic creates the basis for the studied SSS and has a guiding effect on the development of morphotectonic units during the Neogene and Quaternary. Late Cenozoic fault tectonics triggered the SSS to incise into the Paleozoic basement. The change in the bedrock lithology has an impact on the fluvial and colluvial sediments as well as their landforms. The latter reflects a conspicuous modification: straight drainage system ⇒ higher sinuosity and paired terraces ⇒ hillwash plains. Climate change has an indirect effect controlling via the bedrock the intensity of mechanical and chemical weathering. The impact on the development of the SSS can be assessed as follows: Tectonics >> climate ≅ bedrock lithology. The three parameters cause a facies zonation: (1) wide-and-shallow valley (Miocene), (2) wide-angle V-shaped valley (Plio-Pleistocene), (3) acute-angle V-shaped valley (Pleistocene), (4) V-shaped to U-shaped valleys (Pleistocene-Holocene). Numerical data relevant for the hydrographic studies of the SSS are determined in each reference area: (1) Quantification of fluvial and colluvial deposits along the drainage system, (2) slope angles, (3) degree of sinuosity as a function of river facies, (4) grain size distribution, (5) grain morphological categorization, (6) grain orientation (“situmetry”), (7) channel density, (8) channel/floodplain ratios. Thermodynamic computations (Eh, pH, concentration of solubles) are made to constrain the paleoclimatic regime during formation of the SSS. The current model of the SSS is restricted in its application to the basement of the Variscan-Type orogens, to an intermediate crustal maturity state.

The crustal motions throughout Germany have not yet been fully understood because the research scope of previous studies often focuses only on some active grabens. Thus, we investigate it in detail to identify the neotectonic motion characteristics and specific deformation-ongoing regions. High accuracy for monitoring and data analyses is required because the expected crustal deformation in Germany is small. For this reason, we use high-precision GNSS time series processing techniques and interdisciplinary data to reflect actual motions and determine the causes of deformation. Also, an advanced technique of discontinuity correction is introduced to unify the fragments of the GNSS coordinate time series for better velocity field reliability. Our findings show that the crustal motions in Germany tend to increase at a maximum speed of +1.0 mm/year. Meanwhile, local subsidence of around $$-$$ - 0.8 mm/year is concentrated in the river basins (e.g., the Rhine, Ems, Elbe, Northern Oder, and Danube) and extensive mining regions. The Earth’s crust here also behaves with noticeable compressions. The intra-plate motion in Germany is $$\sim $$ ∼ 0.8 mm/year. A special region with an extension rate of +4.3 nstrain/year is observed along the North–South trending Regensburg-Leipzig-Rostock shear zone. Machine Learning clusters the 3D plate velocity field in Germany into three distinct regions with increasing speeds: Northwest, East, and Southwest. Significant surface deformations are detected mainly in the Upper Rhine graben, Eifel volcanic field, and Thuringian-Vogtland slate mountains. The harmonic motions of the Earth’s crust in Germany have an amplitude of $$\sim $$ ∼ 4.7 mm, in which the surface loads contribute half to this type of motion. The findings will contribute to the overall picture of neotectonics here.
