This book was released on 1976 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silurian and Devonian rocks are exposed for approximately 8 square kilometers inthe KootenayArc structural province of northeastem Washington. These Middle Paleozoic rocks overlie the Upper Cambrian Metaline Limestone and the Ordovician Ledbetter Formation, which includes slates, siltstones, and limestones. Two Silurian units crop out in this area. Unit A is composed of Lower Silurian graptolitic argillites and siltstones and Upper Silurian siltstones and fossiliferous limestone. These lithologies represent a trend towards shallower water conditions than those operative during deposition of the Ledbetter Formation. Above Unit A lies the quartz granule conglomerate Unit. This unit consists of a silica rich granule conglomerate with associated beds of slate and is interpreted as an inner submarine fan deposit. Devonian rocks are found locally at Limestone Hill. The polymictic Givetian limestone conglomerate crops out at the base of the bill. This conglomerate contains limestone clasts of Lower and lower Middle Devonian rocks, thereby documenting a break in the sedimentary record. The Givetian limestone occurs as float fragments of dark-gray limestone, which preserve a diverse conodont fauna. On the crest of Limestone Hill lies the Frasnian massive and bedded lime stones, which are believed to represent a reef build-up. The post-Paleozoic sedimentary record consists of Quaternary glacial deposits. An olivine trachybasalt of probable Tertiary age crops out for a short distance in the central portion of the map area. The region has undergone several periods of deformation of probable Mesozoic age. The structure is dominated by northeast and northerly trending folds, and northeast and northerly trending steeply dipping normal faults.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two valleys bordering the campus of Hanover College (Hanover, Indiana) expose several sedimentary rock formations of Late Ordovician through Early Silurian age. Listed in descending stratigraphical order they are the Silurian Salomanie and Brassfield formations, and the Ordovician Whitewater, Saluda and Dillsboro formations. The Salomanie Formation consists of the Laurel Dolostone Member, which contains complete specimens of Gravicalymene celebra, and the Osgood Shaley Limestone Member, which contains abundant crinoid ossicles. The Whitewater Formation consists of medium bedded biomicrite. The mostly unfossiliferous Saluda Formation is composed of laminated gray-green dolostone, while the highly fossiliferous Dillsboro Formation consists of alternating thin shale and limestone beds. The Ordovician-Silurian contact is a disconformity. With the exception of the bulk of the Saluda Formation, all of the rocks were deposited in normal marine environments. Abundant fossils from these rock units may be collected in the beds of Crowe Falls and Happy Valley creeks.
