Newfoundland Carboniferous Stratigraphy and Its Relation to the Maritimes and Ireland
Abstract Thick, relatively complete successions of deformed Carboniferous strata are present in a narrow (16 mi maximum width) elongate zone trending from Cape Anguille on the Cabot Strait northeast to White Bay on the east side of the Great Northern Peninsula. Patches of thin, relatively undeformed Carboniferous strata are found west of this zone between Stephenville Crossing and Cape St. George, and east of this zone, bordering Red Indian Lake. Sedimentary facies within the zone indicate that the southeastern margin of the narrow zone was a major high- angle fault periodically active during Carboniferous time. The oldest post-Acadian strata in western Newfoundland (Anguille Group, Early Mississippian age) are thickest in the deformed zone. They are more deformed than younger strata there, and locally reach a slate grade of metamorphism. Strata of Late Mississippian age (Codroy Group and lower part of the Deer Lake Group) are present within and outside of the deformed zone. The Codroy Group is present only in southwestern Newfoundland and the Port au Port Peninsula, where it contains the only proved marine units in the Carboniferous of Newfoundland. The Deer Lake Group (Late Mississippian and Early Pennsylvanian) is present only in the northeastern part of the deformed zone, where it unconformably overlies the Anguille Group and adjacent pre-Carboniferous base-ment. The Upper Codroy, Deer Lake, and Barachois Groups show fanglomerate facies nearest to, and finer grained facies farthest from, the Long Range and Grand Lake faults that bound the deformed zone on the southeast.A period of deformation occurred during
Carboniferous Continental Sedimentation, Atlantic Provinces, Canada
Carboniferous continental strata in eastern Canada are classed into (1) fanglomerate, (2) fluvial, (3) lacustrine, and (4) mixed fluvial and lacustrine facies. Each facies contains formations that are widely distributed geographically and vertically within the Carboniferous strata; each is related genetically to a rift valley framework, basement mobility, and climate. The fanglomerate facies grade laterally into the fluvial facies. They are poorly sorted and crudely stratified. Angular to subrounded clasts, ranging in size from 2 mm to over 1,220 mm, correspond in composition to underlying or nearby upfaulted basement. The fluvial facies contain thick sandstone units alternating with lutite and thin sandstone units. Many thick sandstone units contain one or more cycles of primary structure sequences suggestive of fluvial channel deposits. A typical cycle consists of (1) mud-pebbles at base, (2) cross-stratified sandstone, (3) horizontally stratified sandstone, and (4) ripple-laminated sandstone at top. This sequence suggests fluctuating velocities during the formation of bedforms such as subaqueous dunes, plane bed, channel bars, point bars, or ripples. Horizontal stratification is considered upper flow regime; cross-stratification and ripples, lower flow regime. Channel sandstone units contain as many as four cycles. Rate of valley floor subsidence, rate of lateral channel migration (or rate of channel jumping), rate of base-level changes, and climatic fluctuations are possible controls on the number of cycles within a channel sandstone unit. The interchannel units consist of lutite with persistently uniform sandstone interbeds, and contain mud cracks, current ripples, flutes, grooves, raindrop impressions, amphibian trackways, and horizontal stratification. The sandstone interbeds are interpreted as the basal member of the overbank cycle. The lutite is interpreted as the upper member of the overbank cycle. The lacustrine facies consist of dark- to medium-gray calcareous lutite with interbeds of medium-gray fine-grained sandstone and of dusky-red lutite and sandstone. In addition to the typical lithology described, 6 of the 10 formations assigned to the lacustrine facies are known to contain less typical units of dark-gray calcareous lutite with interbeds of tan-weathering calcilutite. These less typical units contain hopper-shaped casts, mud cracks, red lutite beds, algal biolithites, and a sparse fauna of conchostracans and pelecypods, and are interpreted as a fluctuation from deeper to a shallower water (and perhaps partially subaerial), more saline environment. The more typical rock units of gray calcareous lutite and sandstone show graded and current-worked laminae, plant detritus, pyrite, and contain a fauna of fresh-water fish, pelecypods, and arthropods, which are interpreted as a deeper water, less fluctuating environment of deposition. The lakes thus fluctuated in depth and salinity and covered up to 11,000 square miles during lower Cansoan (middle Carboniferous) time. Hortonian (lower Carboniferous) and lower Cansoan lake deposits exceed 1,000 feet in thickness and pass laterally over short distances into fine and eventually coarse fluvial facies near the margin of the depositional basins. Fine-grained facies of mixed origin consist of intertonguing fine fluvial and lacustrine deposits. These were laid down during the expansion and contraction of the lakes within what was probably a flat central-basin region. A proposed model of Carboniferous continental deposition consists of fanglomerates at the basin margin (or above pre-Carboniferous basement) grading laterally basinward into coarse and then to fine fluvial facies that grade ultimately into basin-center lacustrine facies.
