In the southeastern part, the granite is invaded by parallel sheets and swarms of many
mafic dykes, and rhyolite sheets.
The Mealy Project reportedly covers 261 square-kilometres of the Mealy Lake
mafic intrusion and is contiguous to Altius Minerals Corp.
Rare earth elements in ultramafic and
mafic rocks and their minerals; minor and accessory minerals.
At the center of it all is Kris Holland, founder of
Mafic Studios, whose status as his company's sole employee is increasingly jeopardized as business picks up.
These rocks are cut by Proterozoic
mafic dyke swarms (cf.
In order to assess the possibility that Hg contamination might be, at least in part, from the underlying bedrock, we present Hg analyses of biotite-rich granitoid, muscovite-rich granitoid, and
mafic rocks from the area in order to complement previous regional studies.
The coincidence of the trend with
mafic volcanics following the topographic height of land suggests a nearby bedrock source.
These ophiolites are overlain unconformably byNisai Formation (Eocene); the sedimentary facies hosting
mafic intrusions.
Gold mineralization primarily occurs within multiple quartz carbonate brecciated zones within bleached units of variolitic
mafic volcanics and other parallel footwall zones.
At a modest cost, and over a 5 to 10 year life-span, it would aim at providing the most comprehensive and multidisciplinary knowledge base of the complete record of
mafic magmatism in and around Canada, and through stimulating international cooperation, around the world.
The Siluro-Devonian Fogo Island Batholith is a high-level, bimodal, sill-like unit about 7 km thick, intruded by a slightly younger, heterogeneous
mafic unit.
The primary target is PGM mineralization hosted by altered
mafic volcanic and
mafic intrusive rocks, and chemical sediments.
