Lithology description: interbedded limestone and mudstone, in roughly equal proportions. mudstone thin bedded and poorly fossiliferous. limestone consists of thin to medium bedded skeltal packstones and grainstones, and calcisiltite. skeletal grainstones commonly cross-bedded and megarippled. calcisiltites commonly with planar lamination, hummocky cross-lamination, tool marks, and trace fossils.
Environment:deep subtidal ramp Tectonic setting:foreland basin
