“…It is noteworthy that this fine, calcrete‐bearing facies of the Dorchester Cape Member also typically overlies the conglomeratic base of the Bonaventure (now Hopewell Cape) Formation in eastern Quebec (Jutras & Prichonnet, ; Fig. ) and in the Moncton Basin of southern New Brunswick (Jutras et al ., ). However, this fining‐upward pattern is not observed in the time‐equivalent Middleborough Formation, which coarsens upward slightly (Fig.…”

Complex interplay of faulting, glacioeustatic variations and halokinesis during deposition of upper Viséan units over thick salt in the western Cumberland Basin of Atlantic Canada

The late Palaeozoic Cumberland Basin of Nova Scotia and New Brunswick (eastern Canada) developed as a strike-slip basin in the aftermath of the Middle Devonian Acadian Orogeny. Following deposition of thick salt during the middle Vis ean (middle Mississippian), this basin mainly accommodated fault-controlled continental deposits during the late Vis ean, which generated halokinesis from clastic loading. The Mississippian halokinetic history of this basin is cryptic, as it was severely distorted by subsequent tectonic and halokinetic overprints. After minor structural restoration, the study of upper Vis ean minibasin units in wide coastal sections and deep wells allowed a fairly detailed reconstruction of the Mississippian halokinetic setting to be made. Paleoenvironments and depositional settings in the western part of the basin include sectors that were proximal to three fault-bounded source areas and characterized by alluvial fan systems transitioning laterally into gravelly to sandy braidplain environments. More central areas of the basin were characterized by tidal flats transitioning laterally into shallow marine environments. Because of halokinesis, the marine body was eventually forced to subdivide into three separate salt expulsion minibasins. Although late Vis ean marine incursions were short-lived in the rest of eastern Canada due to ongoing glacioeustatic variations, there are sedimentologic and stratigraphic lines of evidence for the long-lasting entrapment of restricted marine bodies in salt expulsion minibasins of the western Cumberland Basin. In one minibasin that was characterized by especially high accommodation rates, NE of Hopewell Cape (New Brunswick), the proximal conglomerates and marine carbonates of a fan-delta setting transition laterally into thick sulphate over a short distance, away from freshwater inputs from the source area. The vertical continuity of the latter sulphate succession suggests that this entrapped evaporitic basin was cut-off from significant marine influxes, even at times of glacioeustatic highstands. This is in contrast with salt expulsion minibasins in open marine shelf settings, which always remain open to global marine transgressions and regressions.

“…The fact that in the El Palmar Dam or Quebracho sections the ground water effects are more prominent in the siliciclastic deposits, and less so in the lacustrine is an indication of a very shallow water table that modified the sediments when it rose to form a shallow lake. It is important to note that the groundwater calcretes described here do not correspond to massive and thick phreatic hard pans, such as those described by Jutras et al (2007) for the Mississippian of Canada. Rather, they are here restricted to the more porous levels and tend to preserve their initial textures.…”

The first known geological excursion by a North American college was conducted in 1835. Twenty staff and students belonging to Williams College -a liberal arts college in Massachusetts, USA -explored the geology bordering the Bay of Fundy in northeast Maine, New Brunswick and Nova Scotia. Led by two young professors of natural history, Ebenezer Emmons and Albert Hopkins, the party made extensive observations around Pasammaquoddy Bay, Saint John, Parrsboro, and Windsor, as well as more widely through the Minas and Cumberland basins. Although partly following in the footsteps of two pioneering Bostonians, Charles Jackson and Francis Alger, who had reconnoitred the region in the late 1820s, the Williams College party nevertheless made several original observations. One of most important was a study of the anatomy and paleoclimatic significance of permineralized plants from Joggins and Grindstone Island undertaken by Emmons. This was only the second study of its kind worldwide and later inspired William Dawson to do similar work. Largely overlooked by historians of geology, the Williams College expedition, which comprised a four-week voyage of about 1800 km, illustrates well the challenges and opportunities of geological field work in the early Nineteenth Century. rÉSUMÉLa première excursion géologique connue d'un collège nord-américain a été réalisée en 1835. Vingt membres du personnel et étudiants du Collège Williams -collège d'arts libéraux du Massachusetts, Etats-Unis -ont exploré la géologie des bords de la baie de Fundy dans le nord-est du Maine, au Nouveau-Brunswick et en Nouvelle-Écosse.
