| Abstract | The geoscientific data presented on this map were collected as part of the five-year NATMAP Shield Margin Project (1991-1996) by the Geological Survey of Canada and Manitoba Energy and Mines. The map is
based on field work, air photo interpretation (1:60 000 scale aerial photographs), LANDSAT TM imagery, SRTM digital elevation data, and available drift composition. The glacial erosional record in the Herb Lake map area indicates multiple ice flow
events, primarily related to the last cycle of glacial advance and retreat of ice originating from the Keewatin Sector to the north. The rarity of older glacial sediments beneath surface till demonstrates almost complete glacial erosion during the
latest glacial events hence the lack of significant compositional masking of the underlying bedrock, a situation favourable to drift prospecting. Following deglaciation, the area was inundated by Lake Agassiz. Extensive glacial lake deposits cover
the area with thicknesses ranging from a thin veneer to tens of metres. |
