Lithology Comments

Aug 15, 2011 (A Wilson) - Well layered, fine- to medium-grained, pink, feldspar-rich paragneiss (meta-arkose) with a penetrative foliation. Has the appearance of a sandstone. Thin layers (2-3 mm.) of slightly coarser grained arkosic material are spaced about 7.5 cm to 15 cm. The foliation is also defined by 3-4 mm thick layers of flattened quartz rods, layers of biotite-amphibolite and disseminated biotite and magnetite grains. Thin seams (~0.5 cm. wide) of medium-grained biotitic amphibolite are spaced about 0.2 to 1.0 metre apart. There appears to be abundant attractive, flat stone in this area, particularly suitable for the production of 10 cm (4n) veneer and thicker sills and steps.
