Model for glaciotectonism.

Abstract

Most glaciotectonic disturbances are thought to develop in a largely frozen state, and the possibility of large-scale subglacial thrusting beneath thick ice or far back from the ice margin is generally believed negligible. The majority of severe glaciotectonic deformations in central North America and northern Europe are found in transitional zones, which separate the central glaciated zones characterized by deep glacial erosion from marginal zones, where glacial deposition was the rule. Glacial thrusting provides a mechanism for stripping sedimentary cover off the Canadian and Fennoscandian shields during repeated Pleistocene glaciations.- from Author
