Welcome to the Mineral Exploration Research Centre
The Mineral Exploration Research Centre (MERC) is an exploration geoscience centre focused on Precambrian ore systems research, education, and exploration methodology and targeting. It is a semi-autonomous research centre at Laurentian University (LU) that is affiliated with the Harquail School of Earth Sciences (HES) and one of seven mining-related research centres and departments at LU that form an integral part of the Goodman School of Mines. For more information about MERC, please contact the MERC Director Dr. Ross Sherlock or Associate Director Dr. John Ayer.

2018-03-14 Shock metamorphic features in mafic and ultramafic inclusions in the Sudbury Igneous Complex: Implications for their origin and impact excavation
The lowermost, discontinuous parts of the impact-generated Sudbury Igneous Complex (Canada), comprising the Sublayer and Offset Dikes, are distinguished from overlying Main Mass norite rocks by the presence of abundant inclusions and Ni-Cu-PGE (PGE—platinum group element) sulfide mineralization. The majority of the felsic to mafic inclusions appear to be derived from the exposed country...

2018-03-02 The Paleoproterozoic MacLellan deposit and related Au-Ag occurrences, Lynn Lake greenstone belt, Manitoba: An emerging, structurally-controlled gold camp
The Paleoproterozoic Era is important for Au-Ag mineralization, including deposits in the Trans-Hudson Orogen of central Canada. The association between Au-Ag deposits and regional structures that formed during this era has seen markedly less research than Archean counterparts. The MacLellan deposit and related Au-Ag occurrences occur within the northern part of the Paleoproterozoic Lynn Lake...

2018-02-27 Geology, lithogeochemistry and U-Pb geochronology of the Aberdeen Lake area, Nunavut: New insights into the Neoarchean tectonic evolution of the central Rae domain
The Aberdeen Lake supracrustal belt is one of several Neoarchean greenstone belts preserved within the Rae domain of the Western Churchill Province. We divide the belt into: (1) a Lower Sequence of ca. 2750 Ma komatiite, TTG (tonalite-trondhjemite-granodiorite) intrusions, and TTG-contaminated Fe-tholeiitic mafic gneiss; (2) a Middle Sequence of ca. <2687 Ma psammopelite gneiss, iron...
