Under steady state flow in glaciers, a banding will form and tend towards parallelism with the flow lines in basal regions of high shear. A simple mathematical model shows that departures from the steady state cause a reorientation of the flow lines such that they depart from parallelism with the banding. If a suitable bedrock ridge is present, the banding will subsequently become deformed into subsimilar folds, whose axial surfaces are very nearly parallel to the direction of maximum extension…

The zone of renewed flow at the base of an ice fall on the Gulkana Glacier, in the eastern Alaska Range, lies below the firn limit, and thus the structures in the perfectly exposed ice can be studied…

The regional average basal shear stress τ of a thrust sheet of thickness H is equal to the down-surface slope stress ρgHα. Thrusts always move in the direction of surface slope α, even if they are…
