Abstract | Lower Paleozoic strata occur offshore Labrador (Middle to Upper Ordovician), offshore Baffin Island in western Davis Strait (Upper Ordovician), as well as onshore Baffin Island (Cambrian to Silurian).
Paleozoic carbonate rocks (limestone and dolostone units) dominate with occurrences of siliciclastic strata found in the offshore Labrador subsurface (in the Freydis B-87 well) and in outcrop on Baffin Island. In the Labrador-Baffin Seaway, Lower
Paleozoic strata primarily exist as isolated erosional remnants, where historically, minimal effort has been made to correlate Paleozoic outliers due to their lateral discontinuity coupled with inconsistent age data. The Lower Paleozoic of the
Labrador-Baffin Seaway and Baffin Island can be viewed as two subsets that do not appear to be correlatable: the southern Lower Paleozoic of the Labrador margin and the northern Lower Paleozoic of the southeastern Baffin Shelf and onshore Baffin
Island. |
Summary | (Plain Language Summary, not published) Lower Paleozoic strata composed of Cambrian, Ordovician, and Silurian carbonate and siliciclastic rocks occur offshore Labrador (Middle to Upper
Ordovician limestones and dolostones), offshore Baffin Island in the western Davis Strait (Upper Ordovician limestones), as well as onshore Baffin Island (Cambrian to Silurian). Lower Paleozoic strata is not continuous across the region and occurs
for the most part as isolated erosional remnants. Paleozoic strata in the Labrador-Baffin Seaway and onshore Baffin Island is largely understudied due to its sparse nature and the lack of age control. An overview of the research on the ages and
lithologies that compose the lower Paleozoic strata in the three main regions is presented in this paper and correlations within theses regions and between regions is discussed. This paper is Paper 4 in the Baffin Island and the Labrador-Baffin
Seaway Geological Synthesis, a Geo-mapping for Energy and Minerals GSC Compendium. |
