.... Many wells were drilled in this area from 1869 to present and although most encountered oil shows, no commercial discoveries were made. The oil seeps are either associated with upper Horton Group (Ainslie Formation) or basal Windsor Group (Macumber Formation) sediments. The biomarker distributions...

Les suintements d’huile rapportés plus tôt par d’autres travailleurs sont situés près de failles importantes, et sur des surfaces de joints dans des dolomies minces qui sont intercalées dans des pélites lacustres noires...

... of a tectonically thinned crust. Earlier rift deposits consist of the nonmarine coarse clastic sediments of the underlying Tournaisian Horton Group, and the Horton to Windsor succession defines a typical rift and sag transgressive event. The Macumber and stratigraphically equivalent Gays River Formations...

... the deposit, where the Upper Windsor lies directly on the Lower Windsor Group. These unconformities are considered to be associated with the regional Ainslie detachment, which is consistently found on Cape Breton Island at the top of the Macumber Formation, i.e., at the limestone and evaporite contact...

... provide permissive support for either process, especially in the Walton and Gays River areas. Tectonic breccias, developed in Macumber Formation carbonates during movements associated with the Ainslie detachment, are the main host of the Jubilee deposit. In all three deposits, however, open-space filling...

...Denis Lavoie; D. F. Sangster; Martine M. Savard; Francine Fallara Abstract Base metal occurrences in the Mississippian Windsor Group (Nova Scotia, Canada) are commonly associated with carbonate breccias in the Macumber Formation. Based on sedimentologic, structural, and diagenetic data, three types...

...R. F. Cormier; A. M. Kelly Abstract The Fisset Brook formation of sedimentary and volcanic rocks crops out in the Cheticamp area of Cape Breton Island, Nova Scotia. Its stratigraphic age has been determined as earliest Mississippian using spores contained in the sedimentary members. A rubidium...

...Gregory Lynch; Peter S. Giles Abstract The Ainslie Detachment occurs near the base of the Carboniferous Windsor Group, forming a regional flat-lying extensional fault distributed across 10 000 km 2 . New mapping has delineated the structure through southwestern Cape Breton Island and into central...

Macumber Formation is approximately 10 m thick and the upper contact (not shown) of the formation controls the Ainslie Detachment. B. Rare ripple structures in Macumber Formation, which was for the most part deposited below wave base, from...

... it has been divided into the Creignish, Strathlorne, and Ainslie formations ( Williams et al. 1985 ). However, detailed stratigraphic correlations across the area remain uncertain because of major faults, including the Cobequid–Cheducto fault system between the Meguma and Avalon terranes, as well...

... sequence differs from that in the Fisset Brook Formation of the Cheticamp and Lake Ainslie – Gillanders Mountain areas, where rhyolite is at the top of the section. The Lowland Cove sequence contains palynomorphs most recently interpreted as latest Famennian (Strunian) by Martel et al. ( 1993 ). A Rb–Sr...

..., preserved due to polymorphic transformation to α-cristobalite at low temperature. Formation mechanisms for β-cristobalite in high-silica rocks are difficult to discern, as superheating, supercooling, bulk composition, and trace element abundance all influence whether cristobalite crystallizes from melt...

... withdrawal structures on passive continental margins, where expulsion of evaporites below localized depocenters, known as minibasins, leads eventually to the formation of salt welds, at which strata originally above and below an evaporite layer come into contact (e.g., Jackson and Cramez, 1989 ; Jackson...
