Mar 24, 2020 (Therese Pettigrew) - The MacKenzie Granite is a large intrusion consisting of medium- to coarse-grained, pink to slightly greenish granite composed primarily of microcline, oligoclase, quartz, and biotite with accessory sphene, apatite, opaque minerals, and secondary sericite plus epidote (Rogers, 1979). Amethyst-bearing veins crosscut the MacKenzie Granite and the Penassen Lakes Stock (Scott, 1986).
