Abstract
Samples from the present McDermott and classic Buena Vista quarries show that the Buena Vista is a clast-supported siltstone composed primarily of angular, subprismoidal to spherical, monocrystaline quartz. It also contains lithic fragments, muscovite, chlorite, plagioclase, zircons, pyrite, and iron oxide. The stone is poorly compacted, and has a pervasive intergranular porosity, but low permeability. It is well sorted, with grains from 32 to 75 µm (averaging 50 µm, n = 40). Phyllosilicates and elongate quartz grains are aligned parallel to bedding: In hand samples, abundant muscovite grains are seen lying on bedding planes. The quarry facies of the Buena Vista contains some body fossils, including productid brachiopods, but is most notable for its ichnofossil content, especially abundant Zoophycos.
