  abstract = {{A}n analysis of the processes active in the frost environment of high subequatorial mountains makes it possible to propose a model for the stratification of slope deposits. {B}edding is generated by solifluction sheets which move at the speed of a few cm y-1. {S}olifluction involves needle ice, frost creep and gelifluction, and the ground thikness concerned is less than 20 cm. {S}orting takes place by frost heaving. {C}oarse particles are concentrated at the front of the sheets, where matrix materials tend to be washed away, and are then buried by the advancing fine layer. {S}edimentary characteristics allo recognition of several diagnostic features which can be used to indicate the origin of bedding in relic slope deposits situated in mid-latitudes. {T}his model offers an alternative to earlier concepts of the stratification of slope deposits, but further studies are required, since other processes may also generate similar bedding geatures.
