...Ya-Dong Chen; Shoufa Lin; Cees R. van Staal Abstract Cape Breton Island has been interpreted as consisting of four zones of pre-Carboniferous rocks, but the relationships among them are controversial. To help resolve the controversy, we have dated detrital zircons from a conglomerate (part...

... of the geology in the western part of the Ganderian Aspy terrane of Cape Breton Island. Nine new U–Pb (zircon) ages show that the former “Chéticamp pluton” consists of 10 separate plutons of five different ages: late Neoproterozoic (ca. 567 Ma), Cambrian–Ordovician (490–482 Ma), Ordovician–Silurian (442–440 Ma...

...Sandra M. Barr; Robert P. Raeside; Otto van Breemen Abstract The northernmost Cape Breton Highlands are underlain by the Blair River Complex, a distinctive assemblage of basement rocks including felsic and mafic gneisses, foliated gabbroic to granitic rocks, anorthosite, and foliated and unfoliated...

...Fred Baechler; Robert Boehner Abstract Approximately 23% (2700 km 2 ) of Cape Breton Island consists of a wide variety of glaciated bedrock (meta-carbonates, carbonates, and evaporites) that has the potential for karst development. An additional 1100 km 2 of such strata have been inundated by post...

...K. V. Rao; M. K. Seguin; E. R. Deutsch Abstract Results are reported from steeply dipping red sandstones collected at nine sites (45 samples) of the Lower Cambrian Morrison River and MacCodrum formations on southeast Cape Breton Island, which forms part of the Avalon terrane. Demagnetization...

...S. M. Barr; A. M. O'Beirne Abstract The Gillis Mountain pluton is a small composite granitoid intrusion in southeastern Cape Breton Island. It is one of the few plutons of known Devonian age in Cape Breton Island and is particularly significant because of the presence of Cu–Mo mineralization...

...K. L. Currie Abstract Thrust faulting, apparently of major proportions, has been observed at five localities in northwestern Cape Breton Island and inferred at several more. The thrust blocks of Precambrian crystalline rocks and Horton Group clastic sedimentary rocks have over-ridden Windsor Group...

...Robert A. Wiebe Abstract Acadian granitic rocks in northern Cape Breton Island consist entirely of even-grained leucocratic granodiorite and adamellite. The compositional range is small, and the average composition corresponds well with melts that could be generated in the crust. Abundant...

...Robert A. Wiebe Abstract The geology of northern Cape Breton Island is characterized by two structurally and compositionally distinct metamorphic units and an extended history of igneous activity ranging in age from Precambrian to Devonian. The older metamorphic unit (George River Group...

...Randall F. Cormier Abstract Rubidium–strontium whole-rock and mineral ages of granitic rocks from fourteen localities on Cape Breton Island have been measured. The ages cluster about a mean value of about 560 m.y. and indicate that most of the granitic rocks on the island have primary ages...

...Garrett Briggs Abstract: The Mississippi River-Gulf outlet is a channel 36 ft deep and 500 ft wide extending from a point south of Michoud, Louisiana, southeastward across the marshes and Breton Sound into the Gulf of Mexico. The outlet was constructed by the U.S. Army Corps of Engineers to provide...
