...Q. Gall; R.N. Hiscott ABSTRACT The Deer Lake subbasin of the Maritimes Basin developed as a northeast-trending half-graben which was extensively faulted along its eastern side. Within the subbasin, the Deer Lake Group (North Brook, Rocky Brook and Humber Falls formations) and Howley Formation...

...A. P. Hamblin; M. G. Fowler; J. Utting; D. Hawkins; G. S. Langdon ABSTRACT The Rocky Brook Formation (Deer Lake Group) includes lacustrine and fluvial mudstone, sandstone, dolostone and oil shale deposited in the Early Carboniferous fault-bounded Deer Lake Subbasin. Over the past century...

.... Elsewhere, the basal beds of the Barachois Group lie unconformably on pre-Carboniferous rocks. The Barachois Group in the Codroy and St. George’s Bay lowlands correlates with the Humber Falls and Howley formations of the Deer Lake Subbasin of western Newfoundland and with the Pomquet Formation of the Mabou...

... subbasin. The presence of pronounced anticlinal trends, which are likely en echelon fold axes, further supports the notion of significant post-Vis6an deformation. Langdon (1996) has proposed that the Deer Lake Basin had a complex and protracted history that involved Late Devonian-Tournaisian extensional...
