Geology Comments

Dec 07, 2005 (W Bellinger) - GENERAL GEOLOGY AND STRUCTURE: The claims are underlain by Fe-rich augite syenite (Walker et al. 1992) of the Proterozoic Coldwell alkalic complex. Geological mapping over the area was done by Puskas (1967) and recently by Walker et al. (1991, 1992, 1993). Walker et al. (1992) described the iron-rich augite syenite as follows: The iron-rich augite syenite appears to be a low angle sheet-like intrusion, which dips approximately 15 degrees toward the centre of the complex. It intrudes the basaltic xenoliths of the roof pendant and the Eastern and Western Gabbro, and it has inclusions of recrystallized amphibole quartz syenite. A variation in mineralogy from the bottom to the top through the sheet is present and consists of: fayalite-iron-rich, augite-magnetite syenite; iron-rich augite syenite; fayalite-iron-rich augite syenite; and amphibole syenite.

Mineralization Comments

Dec 07, 2005 (W Bellinger) - MINERALOGY: Walker et al. (1992) described the mineralogy of the iron-rich augite syenite: Iron-rich augite syenite, which forms the majority of the intrusion, typically contains iridescent tabular to lath-shaped feldspars with cryptoperthitic intergrowths and up to 30% interstitial, iron-rich augite. Variable amounts of fayalite, amphibole, aenigmatite and rare quartz occur in the subunit. The rock is generally black to olive-brown, coarse grained and massive. JOINTING: There is a well-developed system of widely spaced joints which would allow for the extraction of large blocks. COLOUR: The stone is a dark brown-black on fresh cut surfaces. TEXTURE: The stone is coarse grained.
