Superior Province

The Dumas Formation is uncomformably overlying the Archean Superior Province. It hosts metasediments and intercalated iron formations, as well as peridotite and gabbro bodies, which were identified and separated with the help of both Band ratio and Principal Component Analysis.

The Wawa subprovince is a volcano-plutonic assemblage of 2.88-2.72 Ga rocks (Percival et al. 2006) accreted to the southern part of the Superior Province during the end of the Kenoran Orogeny, ca. 2.69 Ga. Extending approximately 1000 km from NE Minnesota to just south of James Bay, the Superior Province is...

The Wollaston and Mudjatik domains form two of the major subdivisions of the Cree Lake Zone (Lewry Sibbald 1977), and also the eastern part of the western foreland of the Paleoproterozoic Trans-Hudson Orogen (i.e., part of the Hearne Province Hoffman 1989, 1990 Bickford et al. 1990 Lewry Collerson 1990). The present tectonic configuration resulted from the oblique collision of the Superior Province into the accreted Reindeer Zone and Hearne Province during the Hudsonian Orogeny (Fig. 2). 

In these studies a dynamic testing method (the mixing-cell) has been used to measure the sorption kinetics of 4 different radionuclides on Lac du Bonnet granite from the Archean Superior Province of the Canadian Shield. This method has been used previously (2) for measurement of sorption kinetics without the interference of hydraulic dispersion common in many other dynamic techniques.

Even Precambrian Shield regions exhibit remarkable variability in heat production. For example, the exposed part of the Proterozoic Trans-Hudson Orogen in Saskatchewan and Manitoba ( 500 km X 500 km) is a mosaic of different belts of different origins and compositions with different heat production values (Rolandone et al, 2002). Another example is provided by the Abitibi province of eastern Canada, which stands out as a low-heat-production region within the Archean Superior Province (Mareschal et al., 2000a).
