| Abstract/Notes | Glaciation in the area of Charlie Lake, New Brunswick, has produced a granitic till very similar in appearance to weathered bedrock. Portions of weathered granite were moved intact and redeposited as imbricated rafts under basal till. The rafts vary from 0.3 to 2 m in thickness over a 10 m wide exposure and show deep weathering zones and brittle deformation, despite the fact that they are highly friable. The rafts are separated by glacigenic fault planes defined by lenses of diamict and rare clasts of distant origin. They are recognizable only in excavations where fault planes can be seen to delineate slabs of rock imbricated mainly upglacier. Surface weathering features, including core-stones, were preserved during movement over short distances. |
