Machine Learning Focal Mechanism Inversion for Hydraulic Fracturing Induced Earthquakes
(2023-04)Hydraulic fracturing has been found to be a major contributor to the increase in induced seismicity worldwide, with pore pressure, poroelasticity, and coulomb stress transfer identified as the three main triggering ... -
Magnetic Anomalies Near Ore Bodies and Mineralized Zones in the Troodos Ophiolite of Cyprus
(1989-04-15)The Troodos ophiolite in southwestern Cyprus has been a major producer of copper since the Bronze age. As such, the area has been studied and mapped extensively, and most known mineralized areas have been studied. Preliminary ... -
Magnetic Modelling in the Davis Strait and Northern Labrador Sea
(1986-04-15)The Davis Strait is a constricted passage lying between Baffin Island and Greenland. Davis Strait separates the waters of Baffin Bay and the Labrador Sea. There have been disagreements as to the nature of the crust in ... -
Magnetic Properties of a Bermudian Pillowed Lava Flow
(1982-03-15)This study is concerned with the description and interpretation of the opaque mineralogy and paleomagnetic properties of a 3.0 m core interval which is comprised of a pillowed lava flow and basal intrusive sheet taken from ... -
Magnetic Susceptibility of Halifax Formation Slates at the Halifax International Airport: Correlation with Potential for Acid Drainage
(1995-04-15)The disruption by excavation or quarrying of sulphide-rich slate units of the Halifax Formation of the Meguma Group of Nova Scotia leads to oxidation of the sulphides and generation of acid drainage. Construction within ... -
Making Active Transportation more Accessible on the Dalhousie Studley Campus: A Traffic Demand Analysis of LeMarchant Street and University Avenue
(2019-04)This research examines the current use of the University Avenue and LeMarchant Street intersection on the Dalhousie University Studley Campus. The current use by transportation type was determined through physical counts ... -
The Manganiferous Slates of the Cambro-Ordovician Meguma Group at Lake Charlotte, Halifax County, Nova Scotia.
(1985-04-15)In recent years there has been considerable interest in manganiferous sediments of the oceans. This interest is due to the special environment required to form manganiferous sediments, the association with other metals, ... -
Mapping lobster habitat in the Northumberland Strait using multibeam echosounders to assess juvenile lobster conservation zone placement
(2024-04)The Northumberland Strait, located in the southern Gulf of Saint Lawrence, is an important area for scallop and lobster fishing. To mitigate the negative ecological effects of fishing, marine management strategies in ... -
Marginal Marine Foraminifera and Thecamoebians in the Upper Cretaceous to Eocene Deposits of the South-Central Pyrenees, Spain
(1995-04-15)The Upper Cretaceous to Eocene marginal marine sediments, in the northeastern Pyrenees of Spain, is a classic area in which to study sequence stratigraphy. Sequence stratigraphy requires strong sea-level control. The ... -
Marine and Coastal Geology Between Hartlen Point and Jeddore Cape, Nova Scotia
(1982-03-15)Acoustic and sample data have been collected in a 600 km2 area of the innermost Scotian Shelf along the Eastern Shore just east of Halifax. In addition sediment distribution has been mapped and rates of coastal change ... -
Marsh Foraminiferal Distribution in the Minas Basin and their Occurrence in Marsh Cores from the Region
(1983-04-15)The foraminiferal assemblages present along two Kingsport marsh surface transects were delineated into zones with respect to vertical elevation above mean sea level (a.m.s.l.), and salinities. The highest vertical zonation, ... -
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 ...
