  • Maritime Sediments and Atlantic Geology
    Maritime Sediments and Atlantic Geology V o l . 22 December, 1986 No. 3 Pre-Carbon Iferous TectonostratI graphic Subdivisions of Cape Breton Island, Nova Scotia Sandra M. Barr and Robert P. Raeslde Department of Geology, Acadia University Wolfvllle, Nova Scotia BOP 1X0 Cape Breton Island can be divided into four zones on the basis of contrasting stratigraphy, metamorphism, and plutonism. A Southeastern zone is characterized by late Precambrian volcanism and plutonism, followed by Cambro-Ordovician rift-basin sedimentation and minor volcanism. The Bras d'Or zone to the northwest is underlain by gneissic basement and overlying platformal (carbonate and clastic) sedimentary rocks, intruded by mainly late Precambrian and Qrdovician(?) granitoid rocks. The Highlands zone has a gneissic core flanked by typically lower grade sedimentary and volcanic rocks of probable Precambrian age intruded by diverse and abundant dioritic to granitic plutons ranging in age from Precambrian to Carboniferous. The Northwestern Highlands zone has gneissic basement intruded by varied plutonic rocks including anorthosite and syenite, the latter of Grenvillian age. The nature and significance of the boundaries between these zones are as yet uncertain, but only the Southeastern and Bras d'Or zones are considered to be part of the Avalon Terrane. Des contrastes de stratigraphie. mdtamorphisme et plutonisme permettent de diviser l'ile du Cap-Breton en quatre zones.

  • Rexton Business Park
    REXTON BUSINESS PARK Contact: Ashley Jones General Manager VILLAGE OF REXTON INC. 82 Main Street Rexton, New Brunswick Canada E4W 5N4 Telephone: (506) 523-6921 Facsimile: (506) 523-7383 Email: [email protected] Web Site: www.villageofrexton.com Topography The Rexton Business Park straddles the border of the Village of Rexton and the Town of Richibucto. The park is located adjacent Highway 11’s Exit 57. The park is bound to the east by Highway 11 and to the south by Main Street (Route 134). To the north and west are large, undeveloped tracts of land, ideal for future expansion of the business park. The site of the Rexton Business Park is flat, with virtually no slope in any direction. The site lies on the estuary of the Richibucto River, which empties into Northumberland Strait. However, the site is well above sea level and does not experience flooding. Surface water run-off is to the south and the Richibucto River. The park is well drained and does not experience ponding. The overburden is deep, consisting of a sand/gravel/clay aggregate. The overburden poses no site restrictions and is considered suitable for development. The park is well treed, with the forest canopy largely intact. The predominant species are pine and spruce, interspersed with some poplars. The forest is estimated to be between 50-70 years of age. The current expansion taking place in the southwest section of the park has the densest tree cover, ideal for screening and buffers. Page 1 REXTON BUSINESS PARK Amenities A. MAINTENANCE The Village of Rexton and the Town of Richibucto are jointly responsible for maintenance and snow removal for streets in the park.

First Nation harvest was about 50 % of 1992 values in 1993 for large salmon and about 80 % of 1992 values in 1993 for small salmon . A population estimate using mark-recapture techniques indicated that spawning requirements were met for large salmon but not small salmon in 1992 .
