Contact aureole of the Canaan Granodiorite.

Braithwaite et al. (1976) described the wollastonite outcrop on the southern side of the Holyoake Valley, and its possible economic significance, but did
not discuss the physical conditions of its formation. They recorded scattered tiny crystals of vesuvianite within the main wollastonite body. Later, pale-green vesuvianite was found in calcsilicate rock (P43240) as numerous crystals up to 3 mm across. This rock, however, is known only from a sample discovered on the spoil heap during excavation of the adit at the locality, and its relations to the other rocks present are not known. The vesuvianite is concentrated in an irregular layer up to 15mm wide in the sample and is accompanied by smaller amounts of garnet, wollastonite, quartz, calcite, diopside, and pyrite (Fig. 4A). Wollastonite, quartz, and calcite are adjacent to one another in this part of the rock, whereas within the vesuvianite-free part, wollastonite is locally intergrown with quartz and is also contiguous with calcite.
