A steep walk up the ridge at its lowest point behind the municipal tip provides a stunning view of a thrust plane between these two formations.
The outcrops of Carboniferous sedimentary rocks upstream in Christopher MacLeod brook are now interpreted as a window through a shallow-dipping thrust plane that has transported the basement rocks over the younger rocks.
9), which reveals a regional north-east-southwest trend of gravity variations in the southeastern Cape Breton Highlands, oblique to the trends shown by the VGM analysis, mapped lithological variations, and the orientation of the thrust plane. Although gravity measurements are sparse in this area, gravity values are higher in the northern part of the study area, and tail off in the southeastern highlands, compatible with an interpretation of a thrust fault transporting a thin veneer of basement rocks over younger sedimentary rocks with no root of plutonic rocks in Baddeck River-St.
Movement on the thrust plane postdated the deposition of the Windsor Group carbonate and evaporite rocks (Visean, 342-327 Ma).
As the gravity anomalies are associated with deeper level structures, the geophysical maps support the interpretation of a thin slab of rock transported on the thrust plane. A minimum thickness of 200 m remains across the area.
The degree of shortening shared by the local folds as well as inferred fold bands in between major thrust planes are less than the degree of regional shortening along the profile section nearby it.
Upper layers are folded with sharp anticlines along the thrust planes, which were prone to erosion and occupied by streams and major rivers.
Flat thrust planes, often intrabed dislocations and further the significant tectonic ramps (the systems of thrusts of a "ramp" and "flat" type are typical (e.g.
From the structural maps and from the mine documentation collected, a gradual reduction of an amount of transport on the thrust planes from the lower stratigraphic levels into the overlying strata is apparent.
