The Ming deposit in the northwestern Canadian Appalachians is a metamorphosed, bimodal-mafic, precious-metal (Au, Ag)-bearing and Cu-rich volcanogenic massive sulfide (VMS) consisting of several, spatially proximal lenses sericite- to chlorite-altered rhyodacitic footwall. various (1807 Zone, 1806 South Up Plunge, Down Lower Footwall Zone) have variations Cu, Au, Ag, Zn grades that reflect varying physico-chemical conditions ore formation. This study describes complex mineralogy orebodies...
The crystal growth history of an Au-rich sedimentary pyrite nodule from the Timmins-Porcupine Au camp, Ontario, Canada, has been investigated using Electron Backscattered Diffraction and Laser Ablation Inductively Coupled Plasma Mass Spectrometry techniques to study crystallographic processes controlling metal deportment in structure. Results show four distinct stages characterized by different microstructures, forms trace element compositions. A direct link is observed between octahedral...

Devonian granitoid plutons comprise a major part of the bedrock northwestern Maine representing magmatic expression Acadian orogeny in this northern Appalachian orogen. They are petrographically diverse with minerals characteristic both I- and S-type granites, some cases within same intrusion, compositionally zoned. New LA-ICP-MS ages presented here elucidate timing duration magmatism. The earliest phase magmatism began around 410–405 Ma emplacement Flagstaff Lake Igneous Complex, presence...
The Ming Cu-Zn-Ag-Au volcanogenic massive sulfide (VMS) deposit is hosted by the Upper Cambrian-Lower Ordovician Rambler Rhyolite formation, which consists of a folded northeast plunging felsic dome complex, developed in uppermost segment obducted supra-subduction Baie Verte oceanic tract, north central Newfoundland Appalachians. overlain interstratified mafic volcanic flows and volcaniclastic rocks Snooks Arm Group. upper 1 km formation coherent lithofacies at its base, quartz-bearing...
The metamorphosed Cambro-Ordovician Ming volcanogenic massive sulfide deposit in northern Newfoundland, Canada, is locally overlain by a unit consisting of mafic to intermediate medium- coarse-grained volcaniclastic breccia with up 10 vol % clasts. Analysis via mineral liberation analyzer two clasts, completed using scanning electron microscope observations, allowed the identification number microscopic and submicroscopic electrum grains. These grains occur three types textural settings: (1)...
The Late Silurian Landry Brook and Dickie plutons Charlo plutonic suite underlie a combined area of approximately 80 km2 in the northeastern part Ganderian Tobique-Chaleur tectonostratigraphic belt northern New Brunswick. pluton is divided into three units: gabbro to quartz diorite, monzodiorite monzogranite, monzogranite. A sample from unit yielded U-Pb (zircon) crystallization age 419.63 ± 0.23 Ma. granodioritic stock located near has an 400.7 0.4 Ma, indicating that it younger unrelated...

Abstract Achieving net-zero carbon emissions goals will increasingly rely on critical mineral resources while simultaneously decreasing the extraction, processing and use of hydrocarbons as primary provider energy. Canada is well positioned to contribute this effort through a series innovative policy research initiatives, it Canada's goal be stable supplier minerals into future. To end, Natural Resources Geological Survey invest financial initiatives. This aims generate precompetitive...
