Researchers used an open-source landscape and stratigraphic evolution model (goSPL) to simulate how sediment filled the Polish Trough, part of the Southern Permian Basin, between 285 and 256 million years ago. By testing six different tectonic and climate scenarios, they identified two models that best match known sediment volumes, hiatus timing and depositional depth, and … Read more…
The rise of a mountain range affects moisture circulation in the atmosphere and water runoff across the land surface, modifying the distribution of precipitation and drainage patterns in its vicinity. Water routing in turn affects erosion on hillslopes and incision in river channels on surrounding mountain ranges. In central Guatemala, two parallel, closely spaced mountain … Read more…
Widespread flooding of the Australian continent during the Early Cretaceous, referred to as the Eromanga Sea, deposited extensive shallow marine sediments throughout the Great Artesian Basin (GAB). This event had been considered ‘out of sync’ with eustatic sea level and was instead solely attributed to dynamic subsidence associated with Australia’s passage over eastern Gondwanan subducted … Read more…
