geröll
Geröll refers to a geological term for loose, angular fragments of rock that have been dislodged from their parent rock and accumulated. These fragments are typically larger than gravel but smaller than boulders, ranging in size from a few centimeters to several meters in diameter. Geröll is commonly found in areas where rock weathering and erosion are active, such as mountain slopes, scree slopes, and riverbeds.
The formation of geröll is primarily driven by physical weathering processes. These include freeze-thaw cycles, where
Once dislodged, these rock fragments accumulate through gravitational processes like rockfalls, landslides, and debris flows. The
Geröll deposits can play a significant role in landscape formation and ecological processes. They can stabilize
