MERCURY IN TILL AND BEDROCK, KEJIMKUJIK NATIONAL PARK AREA, NOVA SCOTIA
(2002-04-15)Loons in Kejimkujik National Park (KNP), southwestern Nova Scotia, have the highest levels of mercury (Hg) concentration in blood of any loon population in North America. For the past several years, a multi-disciplinary ... -
Messinian deep-water turbidites and glacioeustatic sea-level changes in the North Atlantic: Linkage to the Mediterranean Salinity Crisis
(1996-06)Our benthic foraminiferal data clearly indicate eight layers of deepwater turbidites during the Messinian (MTL 1-8) and one in the early Pliocene (PTL 1) in Ocean Drilling Program Leg 105, Site 646B. These deep-water ... -
Metamorphism of Metabasites from Parry Island, Georgian Bay, Ontario
(1992-04-15)A garnet amphibolite body in the Parry Island shear zone, Central Gneiss Belt, Grenville Province, shows textural and mineralogical evidence of retrograde metamorphism to amphibolite facies. Garnets with plagioclase coronas, ... -
Metamorphism of the George River Group; Gold Brooks, Victoria County, Cape Breton Island, Nova Scotia.
(1979-03-15)The Precambrian George River Group of Cape Breton Island, Nova Scotia is characterized by metasediments and metavolcanic rock types. A sequence of predominantly feldspathic quartzites slates and quartzites at Gold Brooks ... -
Micro-petrological Analysis of Shergottite Meteorite North West Africa 4468
(2019-04-15)This study investigates the chemical variations within mineral phases in the Martian meteorite sample North West Africa (NWA) 4468. Meteorites are the only samples of Martian rocks that can be studied directly. Their ... -
Mid-Pliocene warm-period deposits in the High Arctic yield insight into camel evolution
(2013-03)The mid-Pliocene was a global warm period, preceding the onset of Quaternary glaciations. Here we use cosmogenic nuclide dating to show that a fossiliferous terrestrial deposit that includes subfossil trees and the ... -
MIGMATITES OF THE MUSKOKA DOMAIN, GRENVILLE PROVINCE, ONTARIO
(1998-04-15)The Muskoka Domain, Central Gneiss Belt, Grenville Province, Ontario, is characterized by widespread highly migmatitic orthogneisses. The purpose of this study is to describe a variety of migmatites and associated rocks ... -
The Mineralogy of the Fifteen Mile Stream Gold District
(1983-04-15)Comparison of two distinct tailings piles from two separate periods of operations, reveals that they are similar in mineralogy and lithology. The proportions in which the minerals and lithic fragments are present, differs ... -
Minor Folds in Coticule Layers and Their Relationship to Regional Fold Evolution, Central Meguma Terrane, Nova Scotia.
(2000-04-15)The highly anisotropic turbidite sequences of the Meguma Group in southern Nova Scotia are folded into upright, noncylindrical, northeast-southwest trending box and chevron folds. Minor folds are well-developed in ... -
Mode of Extrusion of Frenchman's Barn, Dunn Point Volcanic Formation, Arisaig, Antigonish County, Nova Scotia.
(1979-03-15)Frenchman's Barn, near Arisaig, Nova Scotia, is an enigma. It contains some of the textural characteristics of ash flows and lava flows and some which are not common to either. Part of the problem is that many of the ... -
Modeling habitat connectivity and movement of Blanding’s turtles (Emydoidea blandingii) across a fragmented landscape in Rouge National Urban Park, Ontario, Canada
(2019-04)Rouge National Urban Park is a highly fragmented park in Canada’s most populous city, Toronto, Ontario. Habitat fragmentation has been found to hinder conservation efforts due to the associated increased risks of species ... -
MODELING OF A PALEOCENE SUBMARINE CANYON, JEANNE D'ARC BASIN, OFFSHORE NEWFOUNDLAND, TO DETERMINE CANYON FILL LITHOLOGY
(1997-04-15)The Hibernia Paleocene Canyon, located in the Jeanne d'Arc Basin, offshore Newfoundland, was modeled using the BasinMod lD and BasinMod 2D software packages to determine the lithology of the canyon fill. Petroleum industry ... -
Modelling the Critical Habitat of the Bicknell’s Thrush in the Cape Breton Highlands
(2020-04)Bicknell’s Thrush (Catharus bicknelli) is listed as a threatened species under SARA, and identification of critical habitat is a key priority in the species’ recovery. LiDAR data was used to create a habitat suitability ...
