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… CONTINUE READING
