- Title
Formation mechanisms for ice-stream lateral shear margin moraines.
- Authors
Hindmarsh, Richard C. A.; Stokes, Chris R.
- Abstract
The article outlines the study conducted by Richard C. A. Hindmarsh and colleagues on the ice-stream lateral shear formation. Research shows that such structures were formed by differential erosion rates related to lateral variations in the stream velocity and lateral incursion from inter-stream ridges after the thinner stream retreats. Till continuity/deforming bed mechanisms offer a feasible explanation for lateral shear margin moraines but other possible mechanisms require testing and there is an urgent need to examine the internal structure of shear margin moraines.
