Jovian Early Bombardment: planetesimal erosion in the inner asteroid belt
Asteroids Impacts Jupiter Solar System Formation Solar System Evolution
2012/2/23
The asteroid belt is an open window on the history of the Solar System, as it preserves records of both its formation process and its secular evolution. The progenitors of the present-day asteroids fo...

Paleo-erosion rates in Central Asia since 9 Ma: A transient increase at the onset of Quaternary glaciations?
Quaternary glaciation erosion rates Tianshan cosmogenic nuclide magnetostratigraphy 10 Be
2014/4/15
Erosion is a fundamental player of the interactions existing between internal geodynamics and climate, in particular through its influence on the carbon dioxide budget. However, long term (N1 Ma) eros...
