The geology of the property is primarily on the contact zone between the Lac de la Blache anorthositic complex and the cataclastic
gabbro suite and a variably magnetic sequence of cataclastic
gabbro interlayered with paragneiss.
Gabbros are medium grained equigranular with cataclastic
microstructure near fault zones (milonites).
Uranium mineralization occurs within fractures and cataclastic
KlEnppibEncken is an intrusive-related uranium deposit, hosted by brecciated and cataclastic
granite which is strongly enriched in fluorite or hematite.
A series of NE-SW-striking shear and cataclastic
fault zones are located in a belt between the largest Wiborg and Riga plutons.
The Bear Showing at the west end of Sharpe Lake, formerly mapped as an older meta-conglomerate and tonalite assemblage, has been recognized and redefined as a younger felsic intrusive bounded on both sides by cataclastic
bifurcations of the SWFZ.
Also common as clasts are quartz sandstone, red and black siltstone, chert, and cataclastic
Vein fragments in the cataclastic
breccia observed in drill core indicate the epithermal vein zone developed in the hanging wall of an active fault zone.
Klappibacken is an intrusive-related uranium deposit, hosted by a brecciated or cataclastic
granite which is strongly enriched in fluorite.
The tectonic contact zones of the PPZ have not undergone cataclastic
deformation and are therefore supposed to be of late orogenic origin.
Identification of the different varieties is difficult in the field because of their intimate association and widespread cataclastic
and/or mylonitic overprints.
The shear zone, which trends at 30 [degrees] and dips 70 [degrees] northwest, separates phyllonitic hydrid rocks containing small (1 cm in length) rounded, cataclastic
fragments of granite from adjacent sedimentary rocks of the Flagg Cove Formation to the southeast.
