This book was released on 2020 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Wedington Sandstone Member of the Fayetteville Shale is a constructive delta complex in the Chesterian section of the Late Mississippian record in Northwest Arkansas. A comparative analysis of framework grain composition between the Wedington and two other stratigraphically proximal Carboniferous sandstones: the Batesville Sandstone (older) and the Basal Atoka-Spiro Sandstone (younger) has addressed three questions: 1) Is there similarity in sediment provenance for the three sandstones? 2) Do these three sandstone units have a similar sediment dispersal vector? 3) What are likely sediment source terrains for the Wedington Sandstone? Wedington samples overwhelmingly plot as quartzarenites with fewer samples plotting as sublitharenites. Samples from the Spiro also plot as quartzarenites, while Batesville samples contain more lithic and feldspar grains, and plot in the subarkose and sublitharenite fields in Folk's sandstone classification scheme. This suggests that the Wedington and Spiro sands likely share a common sediment source terrain that differs from that of the Batesville Sandstone. Quartz percentages for the Wedington range from 90.5% to 99.2%. Lithic fragments account for 0.0% to 9.5% of grains and were mostly sedimentary rock fragments. Feldspar grains were exclusively alkali feldspars and account for 0% to 1.4% of framework grains. The Wedington delta complex had a northwest to southeast sediment dispersal vector which is similar to the one proposed for the Basal Atoka-Spiro. The Batesville Sandstone, with its different framework grain composition, was dispersed from north-northeast to south-southwest focused through the Illinois Basin. This vector which predates the Spiro and Wedington systems becomes one of the dominant supply systems for the remainder of the Pennsylvanian fill across central Arkansas. Sediment for the Wedington was likely derived from a mix of source terrains including: the Nemaha Ridge, an older recycled sandstone unit, the Appalachian Mountains, and the Canadian Shield.

This book was released on 2019 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Moorefield Shale represents the Meramecian Series in the Eastern Arkoma Basin in northern Arkansas. Lying on the margin of the Mississippi Embayment and Reelfoot Rift, sequence stratigraphic interpretations have labelled the Moorefield Shale a lowstand wedge succeeding the Early Mississippian (Osagean) Boone Limestone conformably and overlain conformably by the Hindsville Limestone/Batesville Sandstone. The unit contains a basal brown-black limestone and succeeding brown-black phosphatic shale. The Moorefield Shale was deposited along the broad, stable cratonic platform on the southern flank of Laurasia, before it's collision with Gondwanaland to form the supercontinent Pangea at the end of the Paleozoic. During this time, the midcontinent region was covered by shallow seas and carbonates covered most of the region. A shallowly dipping carbonate ramp developed in the region providing a foundation for clastic sediment deposition. The Boone Limestone underlies the Moorefield Shale throughout the eastern Arkoma Region however, the Boone carbonate sediment was transported from its origin on the Burlington Shelf in the northwestern part of Arkansas, and thicknesses of the Boone Limestone significantly decrease to the south and east. Thinning of the Boone Limestone has allowed greater accommodation space for succeeding formations in the eastern Arkoma Basin, and has allowed the Moorefield Shale to be considerably thicker in the east. Thicknesses of the Moorefield Shale measure to approximately 100 feet in outcrop, and 350 feet or greater in the subsurface. Due to the lack of research, the Moorefield Shale offers a unique perspective into the stratigraphy and deposition of Mississippian units of the eastern Arkoma Basin.

Book excerpt: Anatomy of a Paleozoic Basin: The Permian Basin, USA By any standard, the Permian Basin of West Texas and New Mexico is a "super basin." With cumulative oil production of nearly 40 billion barrels (Bbbl) and annual production of nearly 2 Bbbl, it's currently one of the most important hydrocarbon-producing basins in the world. More than 29 Bbbl of this production have come from conventional (carbonate and sandstone) reservoirs, about 75 percent from carbonate reservoirs. Approximately 9-10 Bbbl of the basin's cumulative oil production have come from unconventional targets-primarily organic-matter-rich mudrocks and associated facies-during the last 10 years. The Permian Basin contains perhaps a greater volume of these mudrocks than that of any other basin, a major reason for its current global prominence among hydrocarbon-producing basins. The Permian Basin also contains one of the most extensive data sets in terms of wells drilled, cored wells, and adjacent outcrop analogs, providing a basis for studies that not only helps define the distribution of hydrocarbons but also serves as an excellent laboratory for examining basin-forming processes.This two-volume Bureau of Economic Geology Report of Investigations and AAPG Memoir contains 26 papers covering a breadth of Permian Basin topics, including 4 papers on the basin's structural geology, tectonics, and Precambrian geology; 4 papers on its paleontology and biostratigraphy; 16 on its sedimentology and stratigraphy; 1 on its reservoir systems; and 1 that provides a history and synthesis of the major depositional and deformational events that formed the basin. The goal of this set of papers is to capture, in a single publication, the wealth of information and knowledge about Permian Basin geology that has been generated over the 60 years that have passed since John Galley's early comprehensive paper on the basin in 1958.
