Sedimentation processes and facies on a semi-vegetated talus, Lousteau, southwestern France

Description :
A two-year survey of clast displacements on a small rockfall talus at Lousteau, southwestern France, shows that creep reaches up to 19cm/month near the talus apex, whereas the distal segment remains stable. Movements are not distributed homogeneously but concentrate in distinct areas because of the deflection of clasts by vegetation patches. This paper presents data on slope dynamics and facies observed in this talus, and a new sedimentary model that might explain the genesis of certain types of stratified screes is proposed.
