Holocene tufa in the Slovak Karst: facies, sedimentary environments and depositional history [PDF]

Geological Quarterly, 2013
Several tufa complexes are known in the Slovak Karst which is a typical karst area of a temperate climate. This area is built of Mesozoic carbonates, mainly Triassic in age. The karst systems drain carbonate plateaux and lead water to resurgences located in valleys which are up to 300 m deep.

Tectonic Control of a Change in Sedimentary Environment at ~10 Ma in the Northeastern Tibetan Plateau

Geophysical Research Letters, 2018
Tectonic uplift and climate change play a key role in the evolution of sedimentary systems in terrestrial basins. The Qaidam Basin in the northeastern Tibetan Plateau is well suited for studying these processes because of its location and its thick ...

Bedforms and sedimentary structures related to supercritical flows in glacigenic settings

Sedimentology, 2020
Upper‐flow‐regime bedforms, including upper‐stage‐plane beds, antidunes, chutes‐and‐pools and cyclic steps, are ubiquitous in glacigenic depositional environments characterized by abundant meltwater discharge and sediment supply.
