Point Location Description: Quarry

Location Method: Data Compilation

Access Description: GENERAL LOCATION: The site lies within Lot 20, Conc. X on the east side of the C.P.R. line, approximately 1 km north of Marathon (Figure 19). ACCESS: The C.P.R. quarry can be reached by following an access road which follows the tracks, north out of Marathon. The quarry is in a rock outcrop at the north end of a sand pit at the end of the road.



Exploration History

1880: Blocks were removed during the construction of the Canadian Pacific Railway. The quarried blocks were used in the building of bridges to cross the Pic and Little Pic rivers. 1994: Patented claims held by the Town of Marathon.

Geology Comments

Dec 07, 2005 (R Tuomi) - General Geology: 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.

Lithology Comments

Dec 07, 2005 (R Tuomi) - 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. COLOUR: The stone is reddish to dark brown in fresh cut surfaces. TEXTURE: The stone is coarse grained.

Analyses conducted by Geoscience Laboratories, Ontario Geological Survey, Toronto.



Alteration Comments

Dec 07, 2005 (R Tuomi) - 10) COMMENTS/RECOMMENDATIONS: Although the C.P.R. Quarry site itself is not amenable to quarrying due to its small size, there are numerous sites in the immediate vicinity which may have potential. Since the iron-rich augite syenite outcrops over a very large area within the Coldwell Complex, there may be some suitable sites yet to be found.
