Bedford Shale
The Bedford Shale is a shale geologic formation in the states of Ohio, Michigan, Pennsylvania, Kentucky, West Virginia, and Virginia in the United States. Identification and name John Strong Newberry, director of the Ohio State Geological Survey, first identified the formation in 1870. He called it the "Bedford Shale" and designated its type locality at Tinkers Creek near Bedford, Ohio. Details of the type locality and of stratigraphic nomenclature for this unit as used by the U.S. Geological Survey are available on-line at the National Geologic Map Database. The Bedford Shale in northern Ohio is a red, predominantly soft clay shale that grades to grayish-black near its base. Siltstone beds, showing ripples and some as much as thick, are interbedded near the bottom. This red Bedford Shale consists mostly of sandstone and siltstone, and is much more argillaceous from mid-state Franklin County north-northeast to Lorain County on Lake Erie.

Bleb (mineralogy)
In geology, mineralogy, and petrology, a bleb is a small bubble-like inclusion of one mineral within a larger mineral. An example is a bleb of sylvite within chlorite The chlorite ion, or chlorine dioxide anion, is the halite with the chemical formula of . A chlorite (compound) is a compound that contains this group, with chlorine in the oxidation state of +3. Chlorites are also known as salts of chlorous ac .... Blebs tend to be brightly coloured.

Mudrock
Mudrocks are a class of fine-grained siliciclastic sedimentary rocks. The varying types of mudrocks include siltstone, claystone, mudstone, slate, and shale. Most of the particles of which the stone is composed are less than and are too small to study readily in the field. At first sight, the rock types appear quite similar; however, there are important differences in composition and nomenclature. There has been a great deal of disagreement involving the classification of mudrocks. A few important hurdles to their classification include the following: # Mudrocks are the least understood and among the most understudied sedimentary rocks to date. # Studying mudrock constituents is difficult due to their diminutive size and susceptibility to weathering on outcrops. # And most importantly, scientists accept more than one classification scheme. Mudrocks make up 50% of the sedimentary rocks in the geologic record and are easily the most widespread deposits on Earth. Fine sedi ...

Ross County, Ohio
Ross County is a county in the Appalachian region of the U.S. state of Ohio. As of the 2020 United States Census, the population was 77,093. Its county seat is Chillicothe, the first and third capital of Ohio. Established on August 20, 1798, the county is named for Federalist Senator James Ross of Pennsylvania. Ross County comprises the Chillicothe, OH Micropolitan Statistical Area, which is also included in the Columbus-Marion-Zanesville, OH Combined Statistical Area. History Ross County was described by Ephraim George Squier and Edwin Hamilton Davis as having almost "one hundred enclosures of various sizes, and five hundred mounds" in their book, ''Ancient Monuments of the Mississippi Valley'' (1848). They described the Indian-built earthworks as ranging from five to 30 feet in size, and enclosures of one to 50 acres large. These included Serpent Mound, Fort Ancient, Mound City, and Seip Earthworks (both now part of Hopewell Culture National Historical Park), and Newark Ea ...

Argillaceous
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al2 Si2 O5( OH)4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them. They are important constituents of soils, and have been useful to humans since ancient times in agriculture and manufacturing. Properties Clay is a very fine-grained geologic material that develops plasticity when wet, but becomes hard, brittle and non–plastic upon drying or firing. It is a very common material, and is the oldest known ceramic. Prehistoric humans discovered the useful properties of clay and used it for making pottery. The chemistry of clay, including its capacity to retain nutrient cations such as potassium and ammonium, is important to soil fertility. Because the individual particles in clay are less than ...

Tinkers Creek (Cuyahoga River Tributary)
Tinker's Creek, in Cuyahoga County, Ohio, Cuyahoga, Summit County, Ohio, Summit and Portage County, Ohio, Portage counties, is the largest tributary of the Cuyahoga River, providing about a third of its flow into Lake Erie. History Tinker's Creek was named after Captain Joseph Tinker, the principal boatsman of Moses Cleaveland's survey crew, who died in a boating accident while returning to New England in the fall of 1797. Tinker's Creek Gorge Thousands of years ago, when the Wisconsinian Glaciation retreated, dips and valleys like Tinker's Creek Gorge Elevation: were created due to erosion in the underlying shale. The awesome, severely sloped gorge sculpted by Tinker's Creek became a National Natural Landmark in 1967. A raised viewpoint over the gorge is easily accessible from the Gorge Parkway in the Cleveland Metroparks' Bedford Reservation. The stream is sometimes run in whitewater kayaks and is arguably the most challenging creek in the state of Ohio (when there is enough ...

Type Locality (geology)
Type locality, also called type area, is the locality where a particular rock type, stratigraphic unit or mineral species is first identified. If the stratigraphic unit in a locality is layered, it is called a stratotype, whereas the standard of reference for unlayered rocks is the type locality. The term is similar to the term type site in archaeology or the term type specimen in biology. Examples of geological type localities Rocks and minerals * Aragonite: Molina de Aragón, Guadalajara, Spain * Autunite: Autun, France * Benmoreite: Ben More (Mull), Scotland * Blairmorite: Blairmore, Alberta, Canada * Boninite: Bonin Islands, Japan * Comendite: Comende, San Pietro Island, Sardinia * Cummingtonite: Cummington, Massachusetts * Dunite: Dun Mountain, New Zealand. * Essexite: Essex County, Massachusetts, US * Fayalite: Horta, Fayal Island, Azores, Portugal * Harzburgite: Bad Harzburg, Germany * Icelandite: Thingmuli (Þingmúli), Iceland * Ijolite: Iivaara, Kuusamo, Finl ...
