Pliocene to modern sediment routing in the aare valley: implications for sediment recycling

HIGHLIGHTS

• What: The authors show that the modern Aare river carries garnet types incompatible with the crystalline rocks outcropping in the present-day catchment area but compatible with Miocene sandstones of the foreland basin fill. By comparing modern-day fluvial sediment to Pleistocene and Pliocene paleo-Aare deposits the authors show that recycling from the foreland basin has been a dominant sediment generation process since the onset of the Pleistocene glaciation and the incision of river valleys. The study further emphasizes that sediment recycling can be identified using appropriate provenance proxies provenance data are crucial to understanding the . . .
