Abstract

The AA. review the characteristics of lateral shear margin moraines and present 2 quantitative models for their formation : 1) differential erosion rates related to lateral variations in the stream velocity and 2) lateral incursion from inter-stream ridges after the thinner stream retreats, where the shear margin moraine is consequently just a terminal moraine of the inter-stream ridge. The conditions that permit shear margin moraines to form are quite constrained. This is consistent with the infrequent observations of lateral shear margin moraines
