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 1969 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study considers the lowermost Middle Devonian to Late Devonian strata of southern Illinois. In general, these rocks are shallow water carbonates in the lower part and shale in the upper portion. Within the study area these strata increase in thickness from nothing at the west to about 400 feet thick in the southern Illinois deep basin area. The lowermost unit within this section, the Grand Tower Formation, has been extensively discussed by Meents and Swann (1965) and thus will here receive only cursory treatment. The younger formations given more detailed consideration are the Lingle Formation, Alto Formation, Blocher Shale, and Sweetland Creek Shale. The purposes of this investigation are (1.) to determine the thickness and distribution of the formations at and beneath the Middle-Upper Devonian boundary of southern Illinois and (2.) to study the lithologic changes both vertically (stratigraphic) and laterally (facies) within and between the formations. Of particular importance are the relationships between the lower units of the New Albany Shale Group and upper units of the Middle Devonian carbonate sequence. This study is limited to the confines of Middle and Upper Devonian strata of east-central and southern Illinois south of the Vandalia Arch. The significant shale versus limestone facies relations are located south of this arch. Moreover, the carbonates to the north of the Vandalia Arch contain no fine-grained terriginous detrital components. Therefore, their interpretation poses an entirely different problem beyond the scope of this work.
