MARC recordGlacial history, drift composition, and mineral exploration, central Labrador / R.A. Klassen, F.J. Thompson.
| Title: | Glacial history, drift composition, and mineral exploration, central Labrador / R.A. Klassen, F.J. Thompson. |
| Author(s): | Klassen, R. A. Thompson, F. J. |
| Date: | 1993. |
| In: | Geological Survey of Canada. Bulletin. (1993.), Vol. 435 (1993) |
| Abstract: | Ice-flow history and drift composition were investigated between 1984 and 1988 to establish geological framework for mineral exploration. Striae indicate complex history of ice flow, indicating marked change in ice flow direction not shown by glacially streamlined landforms. Shape and orientation of glacial dispersal trains record erosion and transport during succeeding ice-flow events. Regional till composition reflects compositional differences between major geological units and terrains. Glacial dispersal trains can mask bedrock tens to hundreds of kilometres down-ice and can be recognized on geochemical and lithological maps. |
