...Adam Schoonmaker; William S.F. Kidd Abstract The Ordovician Stanbridge Group of Quebec has long been considered an allochthonous nappe. It is an internally coherent unit that consists of lower slaty limestone overlain by slate, which is correlated with the Highgate and Morses Line formations...

...Fig. 14. Field photographs of structural features in the Philipsburg slice. ( a ) Contact between the light grey limestone of Corey Formation (hanging wall) and the black shales of Stanbridge Group along the Northern Frontal Thrust.

... and Stanbridge dolomite ( Hoffman and Pelletier 1982 ). These formations were originally assigned to the Akaitcho Group ( Hoffman and Pelletier 1982 ) but, as discussed below, this correlation is demonstrably incorrect. The Badlands granite ( Hoffman and Pelletier 1982 ) discordantly truncates the Melville Group...

...Lars E. Fåhraeus ABSTRACT Arguments are presented in favour of the continued use of the Beekmantown Group as the representative type of the Canadian Series, thus suppressing recognition of the formally correct Lévis Formation of Quebec as the type-section of the Canadian. Thus defined, the Canadian...

... 2000s indicated by the letter Q. Diagrams B–E indicate the general trends in groundwater abstractions from groups of pumping stations. For some of the sites, estimates of abstraction rates are used for the earlier years of the sequence. Birchmoor pumping station (Diagram B) is in the outcrop...

Isotopic age constraints from the internal zone ( Castonguay et al. 2001 a ) show two groups of metamorphic ages: Middle Ordovician (469–456 Ma) and Silurian...

... Ordovician flysch. The allochthonous domain in the study area consists of Upper Cambrian (?) to Upper Ordovician basin rocks (Citadelle Formation, Oak Hill, Shefford, and Stanbridge groups) and Upper Cambrian to Middle Ordovician platform strata (the Philipsburg and Upton groups, Fig. 2 ). It structurally...

... interested in purchasing this archive, and to this end, a small group of Museum staff visited Sotheby’s in November 2021 to view the Buckland family archive and learn more about the items it contained. Connections between the family archive and OUMNH’s existing Buckland archive and specimens were immediately...

The strata were previously assigned to the Philipsburg Group. Early correlations between the Philipsburg succession and coeval strata of the St...

...F.-A. Comeau; D. Kirkwood; M. Malo; E. Asselin; R. Bertrand Abstract In the Quebec Appalachians, disruption, imbrication, and thrusting of the Taconian foreland basin sequence are responsible for the development of chaotic units within the turbiditic sequence of the Caradocian Sainte-Rosalie Group...
