- Abstract:
- The bedrock topography map of the Pelican River area (NTS 83P) shows the elevation of the bedrock surface. In general, the surface topography reflects the bedrock topography: bedrock highs underlie the Pelican, Amadou and May Hills highlands, and the buried valleys lie within the Wabasca and Wandering River plains. The elevation of the bedrock surface ranges from 360 metres above sea level (masl) in the Wabasca Plain to slightly more than 920 masl in the Pelican Mountains. Segments of three major buried valleys are present: the Wiau Valley and the Leismer Valley in the northeast, and the south to northwest-trending Amesbury Valley in the central portion of the area.
- Purpose: In support of bedrock topography mapping of Northern Alberta at 1:250 000 scale.
- Supplemental Information:
- Petrophysical logs were the primary source of information used for constructing the bedrock topography. A suite of the common well logs (gamma, resistivity, spontaneous potential, density, neutron, sonic and calliper) were useful in making the pick for top of bedrock; however, the gamma and resistivity logs proved to be the most useful. The drift typically displays a lower gamma response and higher resistivity response than the underlying bedrock. Other sources of data were water well lithologs, mineral exploration testholes and information on outcrop locations.
Picking the bedrock surface was difficult in some areas where data were sparse. Many of the log traces were absent from the upper part of the hole because of surface casing. The depth of surface casing set in bedrock was used for an estimate of maximum drift thickness in places with few data. Conversely, many water wells did not penetrate deep enough to intersect the bedrock, so only a minimum drift thickness value could be used.
