The Fox River Belt is a major, underexplored PGE exploration-target in northeastern Manitoba (Figure 1). It hosts the Fox River Sill, an ultramafic intrusion at least km long and up to 2 km wide. According to recent exploration and research, samples collected produced the highest known PGE content ever obtained from the Fox River Sill—up.

Theyer, C. Wegleitner, Geochemistry and tectonic setting of volcanic and intrusive rocks in the VMS-hosting Snow Lake arc assemblage, Flin Flon.

Rb–Sr whole-rock ages have been determined for rocks from the Oxford Lake – Knee Lake – Gods Lake greenstone belt, in the Superior Province of northeastern age of the Magill. The Flin Flon greenstone belt in central Manitoba and east-central Saskatchewan is a collage of deformed volcanic arc rocks ranging in age from 1, to 1, million years old during the Paleoproterozoic sub-division of the Precambrian eon.

Proterozoic rocks of the Circum-Superior belt (3) (apparently) overlie the reworked granulites along the Fox River and in the Thompson belt. They consist of metasedimentary rocks, mafic-ultramafic metavolcanic and associated intrusive rocks; the magmatic rocks are komatiitic in nature suggesting a rifting environment (3,4).

The Superior Craton is a stable crustal block covering Quebec, Ontario, and southeast Manitoba in Canada, and northern Minnesota in the United is the biggest craton among those formed during the Archean period.

A craton is a large part of the Earth's crust that has been stable and subjected to very little geological changes over a long time. The size of Superior Craton is about.

Komati- itic and MORB type volcanics in the Cape Smith Belt (Chukotat Group, not precisely dated) were correlated with similar imprecisely dated rocks of the Ottawa Islands and with the Ga Molson dykes and Fox River Sill (Fig.

The volcanology of Eastern Canada includes the hundreds of volcanic areas and extensive lava formations in Eastern region's different volcano and lava types originate from different tectonic settings and types of volcanic eruptions, ranging from passive lava eruptions to violent explosive n Canada has very large volumes of magmatic rock called large igneous provinces.

The CRGB is a northeast-trending volcanic belt in the Gods Lake Domain of the northwestern Superior Province (Fig. GS). Hubregtse () mapped the CRGB and correlated the rocks with the Hayes River Group - a composite, pre-dominantly basaltic volcanic sequence accounting for the older, volcanic.

The Fox River Belt in northern Manitoba is composed of sediments, volcanics and sills. Fox River Belt sills and Molsen dikes are 1, million years old, but the Molsen dikes at the northwestern Superior craton margin intrude an older, 2, to 2, million-year-old dike swarm.

The Fox River Sill (FRS) is a Paleoproterozoic ( Ma) intrusion that extends for most of the length of the > km long Fox River Belt in northeastern Manitoba (Scoates ).

The sill is a predominantly ultramafic layered intrusion having an average thickness of km. The Great Falls area on the Fox River. The ca. Ma Circum-Superior Large Igneous Province (LIP) consists of a number of discontinuous segments known to cover a significant portion of the margin of the Superior Province craton in North America.

New geochemical and isotopic data from western segments of this LIP support a common origin for the these segments and suggest that magmatism in the Lake Superior region may have been fed.

The inclusion of the Fox River Belt magmatic rocks in the ca. Ma Circum-Superior LIP is based on a U–Pb zircon age determination of + / – Ma from a sample of varitextured gabbro towards the base of the Fox River Sill in the Great Falls area (Heaman et al., ).

Mafic volcanic rocks incorporated within the Churchill-Superior Boundary Zone at Ospwagan Lake, Moak Lake, Assean Lake and the Fox River Belt constitute part of the Circum-Superior Belt. Major and trace element data have been obtained from mafic and ultramafic volcanic rocks from four localities.

An important component of this magmatism is the Ga Molson Igneous Events, which comprise the Molson dyke swarm, various ultramafic sills and mafic volcanic rocks located in both the Fox River and Thompson Nickel belts, northern Manitoba.

The Fox River Belt The Fox River Belt (Scoates,and i prep.) borders the northeast n part of the Superior Province craton in Manitoba for approximately km. The belt, which consists of sedimentary rocks, large differentiated sills, and ultramafic to mafic volcanic rocks, forms a 15 t o 20 km wide north-facing homoclinal sequence.

Precise U-Pb zircon ages have been obtained for samples from the Molson dyke swarm and the Fox River sill in NE Manitoba, Canada. The ages determined for the Cross Lake and Cuthbert Lake dykes are 1, − + and 1,±2 Ma, respectively, and are in excellent agreement with the 1, − + Ma age obtained for the Fox River sill.

Northern Gneiss Belt rocks in the Fox River, approximately m north of the inferred northern contact of the Fox River Belt (Fig. GS). Several samples were collected from the paragneiss units that were observed in these outcrops.

These samples will be used to study the Nd-Sm model ages for the rocks, an extension of the work being done by.The Fox River Belt stratigraphy is divided into three sedimentary and two volcanic formations with two suites of intrusive rocks.A Nd isotopic study was carried out on − Ga rocks from two parts of the Trans-Hudson Orogen in northern Canada.

The first part is the Reindeer Lake Zone in the Churchill Province in Saskatchewan, where a variety of volcanic, granitoid, and sedimentary rocks are preserved in several lithotectonic belts that border a reworked Archean craton to the northwest.
