Dec 07, 2005 (W Bellinger) - GENERAL GEOLOGY AND STRUCTURE: Hinz and Lucas (1992) described the general geology: The area is underlain by rocks of the Winnipeg River (to the south), the English River (the centre) and Uchi Lake (to the north) subprovinces. The Winnipeg River Subprovince is composed of granitic intrusives and gneissic domes. The English River Subprovince consists of primarily metasedimentary migmatitic rocks. The Uchi Subprovince contains metasedimentary and metavolcanic belts with gneissic-intrusive complexes between the belts.

Dec 07, 2005 (W Bellinger) - MINERALOGY: Raoul (1992) provided a petrographic description of the stone: The rock is a medium-grained, pink granite with a uniform colour and texture. The colour gradually gets a little lighter to the south. There is some biotite and minor leucoxene (a titanium oxide which forms from the alteration of ilmenite). The leucoxene is deleterious due to the fact it is soft and weathers easily. The mineral constituents are: orthoclase (40%), plagioclase (30%), quartz (25%), and biotite (5%). JOINTING: The outcrop has very few vertical fractures, only three persistent joint were observed. However, considerable sheeting is observed and ranges in thickness from 0.2 m to 1.25 m in the western portion of the site. COLOUR: The rock is a pink granite. TEXTURE: The stone is medium grained.
