Stratigraphic Unit
A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it. Units must be ''mappable'' and ''distinct'' from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%". Lithostratigraphic units Sequences of sedimentary and volcanic rocks are subdivided the basis of their shared or associated lithology. Formally identified lithostratigraphic units are structured in a hierarchy of lithostratigraphic rank, higher rank units generally comprising two or more units of lower rank. Going from smaller to larger in rank, the main lithostratigraphic ranks are Bed, Member, Formation, Group and Supergroup. Formal names of lithostratigraphic units are assigned by geological surveys. Units of formation or hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian.

Willard, Kansas
Willard is a city in Shawnee and Wabaunsee counties in the State of Kansas in the United States. As of the 2020 census, the population of the city was 74. History Before 1883, Willard was a tiny community but when the Rock Island Railroad laid tracks through it, Willard became a typical railroad town. In 1887, the Chicago, Kansas and Nebraska Railway built a main line from Topeka through Willard to Herington. The Chicago, Kansas and Nebraska Railway was foreclosed in 1891 and taken over by Chicago, Rock Island and Pacific Railway, which shut down in 1980 and reorganized as Oklahoma, Kansas and Texas Railroad, merged in 1988 with Missouri Pacific Railroad, merged in 1997 with Union Pacific Railroad. Most locals still refer to this railroad as the "Rock Island". In the early 1920s, Willard boasted a population of over 300 and was a major cattle shipping point for this region. During the 1930s Great Depression many businesses closed, the railroad became less important. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kansas
Kansas () is a state in the Midwestern United States. Its capital is Topeka, and its largest city is Wichita. Kansas is a landlocked state bordered by Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. Kansas is named after the Kansas River, which in turn was named after the Kansa Native Americans who lived along its banks. The tribe's name (natively ') is often said to mean "people of the (south) wind" although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison. The first Euro-American settlement in Kansas occurred in 1827 at Fort Leavenworth. The pace of settlement accelerated in the 1850s, in the midst of political wars over the slavery debate. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wabaunsee Group
The Wabaunsee Group is a Late-Carboniferous geologic group in Kansas, extending into Nebraska, Iowa, Missouri, and Oklahoma. The unit is recognized in the subsurface by drillers in Colorado as Wabaunsee Formation. In locations, some upper members are not present due to a series of erosions that occurred in late-Pennsylvanian time. , 1986 (Revised November 2018).

Emporia Limestone
The Emporia Formation, also referred to as Emporia Limestone, is a Late-Carboniferous geologic formation in Kansas, extending into Nebraska, Iowa, Missouri, and Oklahoma. This formation's members are, top to bottom, * Elmont Limestone, named for Elmont, Kansas (Beede, 1898) * Harveyville Shale, named for Harveyville, Kansas (Moore, 1936) * Reading Limestone, named for Reading, Kansas (Moore, 1936) While the Elmont Limestone member is generally less than 3 feet thick (1 meter), it can be as thick as 15 feet (5 meters) and as thin as 12 inches. As thin as that, it is particularly resistant and forms multiple waterfalls within a few miles along Deep Creek in southern Riley County, including Pillsbury Crossing Pillsbury Crossing is a natural limestone slab that was used by pioneers to cross Deep Creek.

Formation (geology)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Pillsbury Crossing
Pillsbury Crossing is a natural limestone slab that was used by pioneers to cross Deep Creek. The ledge terminates in a waterfall in Riley County, Kansas, USA. The waterfall is about wide and has a drop of around . Below Pillsbury Crossing, Deep Creek flows into the Kansas River. The waterfall is named for Josiah Pillsbury, a Free-Stater (Kansas), Free-State settler in Kansas Territory who homesteaded by the crossing in 1855. Pillsbury was a member of the Free-State Topeka Constitution, Topeka Legislature and the failed Leavenworth Constitutional Convention. The site is part of Pillsbury Crossing Wildlife Area.

Riley County, Kansas
Riley County (standard abbreviation: RL) is a county located in the U.S. state of Kansas. As of the 2020 census, the population was 71,959. The largest city and county seat is Manhattan. Riley County is home to two of Kansas's largest employers: Fort Riley and Kansas State University. History Riley County, named for Mexican–American War general Bennet Riley, was on the western edge of the 33 original counties established by the Kansas Territorial Legislature in August 1855. For organizational purposes, Riley County initially had attached to it Geary County and all land west of Riley County, across Kansas Territory into present-day Colorado. The first Territorial Capital of Kansas Territory was located in the boundaries of Riley County, in the former town of Pawnee. The site now falls within the boundaries of Fort Riley, a U.S. Army post. Manhattan was selected as county seat in contentious fashion. In late 1857, an election was held to select the county seat, with Ogden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
