Cool Quarry complex
Cool Quarry complex
Permian
Equivalent to the Cool Quarry terrane of Graymer and Jones (1994). Interpreted as a deformed remnant of a seamount. Cool Quarry complex might be a giant olistolith in the Clipper Gap Formation (unit YACG), based on position at the contact between Clipper Gap Formation and Lake Combie complex (unit YALC) and the similarity between the marble member and marble blocks in the Clipper Gap Formation. However, the presence of serpentinite along the eastern boundary fault, probably derived from the Mount Ararat terrane to the south or the Lake Combie complex to the west and north, shows substantial deformation at the unit margin.
