| Species: | Microcline |
| Formula: | K(AlSi3O8) |
| Comments: | A major component of the pegmatites. In the perthitic microcline-quartz zone of the No.1 quarry, in large anhedral crystals as much as 10 feet long. In the eastern part of the north wall, the zone is richest in massive perthitic microcline toward the center of the pegmatite, and this suggests the presence of a perthitic microcline core. Locally, the microcline is veined and partly replaced with granular milky quartz, deformed muscovite and pink-red garnet. Graphic granite is fairly common. |
