Evidence of upgrading of gold tenor in an orogenic quartz-carbonate vein system by late magmatic-hydrothermal fluids at the Madrid Deposit, Hope Bay Greenstone Belt, Nunavut, Canada

Autor: Mostafa Fayek, Mitchell J. Kerr, Jacob J. Hanley, Joseph A. Petrus, Daniel J. Kontak, Zoltán Zajacz, Gordon G. Morrison

Publikováno v: Geochimica et Cosmochimica Acta. 241:180-218

Evidence of secondary gold enrichment due to the addition of new gold into an earlier orogenic quartz-carbonate vein deposit by magmatic-hydrothermal fluids is strongly suggested for the Madrid Deposit, hosted in the Hope Bay Greenstone Belt in Nunav

Preliminary Evaluation of Trace Hydrocarbon Speciation and Abundance as an Exploration Tool for Footwall-Style Sulfide Ores Associated with the Sudbury Igneous Complex, Ontario, Canada

Autor: Jacob J. Hanley, Colin J. Bray, John Everest, Mitchell Kerr, Gordon G. Morrison

Publikováno v: Economic Geology. 110:531-556

Deposits of Cu-Ni-platinum group elements (PGE)–rich sulfides occur along the North Range footwall of the Sudbury Igneous Complex, Ontario, Canada. The deposits have been modified chemically, mineralogically, and texturally by multiple syn- to post

Petrogenetic significance of chromian spinels from the Sudbury Ignecus Complex, Ontario, Canada

Autor: Peter C. Lightfoot, Gordon G. Morrison, Mei-Fu Zhou, Michelle L. Moore, Reid R. Keays

Publikováno v: Canadian Journal of Earth Sciences. 34:1405-1419

Chromian spinels occur in mafic–ultramafic inclusions in the Sublayer of the Sudbury Igneous Complex (SIC) as well as in mafic–ultramafic rocks in the immediate footwall of the Sublayer. The host rocks are pyroxenite and melanorite with minor dun

Geologic and geochemical relationships between the contact sublayer, inclusions, and the main mass of the Sudbury Igneous Complex; a case study of the Whistle Mine Embayment

Autor: Peter C. Lightfoot, Keith P. Farrell, Andy Bite, Reid R. Keays, Gordon G. Morrison

Publikováno v: Economic Geology. 92:647-673

More than half of the giant Ni-Cu-platinum-group element (PGE) sulfide ores of the Sudbury Igneous Complex are associated with a discontinuous unit at the base of the main mass known as the "sublayer." The sublayer is comprised of two fragment-rich m

Geochemical relationships in the Sudbury igneous complex; origin of the main mass and offset dikes

Autor: Gordon G. Morrison, Reid R. Keays, Andy Bite, Keith P. Farrell, Peter C. Lightfoot

Publikováno v: Economic Geology. 92:289-307

Petrological models relating the different rock types constituting the 1.85 Ga Sudbury Igneous Complex are constrained with extensive new geochemical data. We show that the main mass felsic norite, transition zone quartz gabbro, and granophyre have s
