Dec 07, 2005 (C Papertzian) - 86-ELZ-007 : Elzevir Granite. Grey-whiite granite, medium-grained, foliated with moderate to intense jointing. There are abundant quartz stringers (av.1 cm wide), minor quartz veining and common exfoliation (1-2 cm thick). Potential for quarry blocks is poor to moderate.
Dec 07, 2005 (C Salo) - The area was mapped by Dillon and Barron (1985) as mafic to ultramafic metavolcanic rocks in contact with the Elzevir granodiorite batholith which lies to the east. Talcose rock occurs within the metavolcanics adjacent to the batholith and as lenses within the batholith. In this location the width of the talc units ranges from 2 to 15 m. They are up to 60 m in length (see Figure 39).

Dec 07, 2005 (C Salo) - The talcose rocks are described as soft, massive to poorly foliated, with a light greenish grey to pinkish grey colour on weathered surfaces. Fine carbonate veinlets occur throughout the unit, commonly associated with chlorite and magnetite (Dillon and Barron 1985). Thin section examination by Dillon and Barron (1985) indicates the talc content of the rock varies from 20 to 80 percent and carbonate up to 30 percent. Chlorite, serpentine and magnetite occur in varying amounts.
