Lithology

Lithology Comments

Jul 27, 2022 (Therese Pettigrew) - The Revell Batholith is a north-northwest trending elongate granitoid body. It is apparently contiguous with a large area of granitoid plutons extending from Highway 502 in the west to the Keweenawan diabase sills near Lake Nipigon. The rock is fine- to medium-grained, white biotite granodiorite. The rock is massive with an equigranular texture. Joints are for the most part wide spaced (3 m or more). Predominant directions are north and southeast with a lesser direction east-northeast. There are no obvious inclusions in the outcrops examined although mapping by Satterly (1960) indicated a large roof pendant in south central Revell Township. Foliation is absent except in a narrow zone along the contact. The biotite content is 5 to 10%. The rock polishes well. The quartz is clear and colourless; the feldspars are colourless to white, some show distinct zoning on the polished specimen. Surface samples show a small amount of orange-brown stain associated with biotite and one outcrop near the north contact of the body showed a 1 cm weathered rind under thick moss and vegetation cover (Storey, 1986).

Mineralization

Mineralization Comments

Jul 27, 2022 (Therese Pettigrew) - In the Dyment area the granodiorite mass is remarkably uniform in composition. The rock is quite massive, and foliation was only observed near the margins of the batholith. The granodiorite is a pink and white to grey, medium- to almost coarse-grained rock composed essentially of oligoclase, microcline, quartz and biotite. Muscovite may be present, associated with biotite. Parts of the oligoclase are replaced by clusters of white mica and clinozoisite. The biotite forms large flakes or cluster of flakes usually accompanied by the accessory minerals epidote, apatite, sphene, and rarely zircon. A few flakes of molybdenite were seen in the granodiorite on the Dryden Paper Company's road in lot 6, concession III, Revell Township (Satterly, 1960).

Jul 27, 2022 (Q Unknown) - Quarry is 12 m by 4.5 m by 1 m in size. Produced 54 cubic meters of stone.
