How rocks are named. In the same way that biologists use categories to identify animals and plants, geologists have created categories such as formations, groups, and members to distinguish one rock layer from another. Clockwise, from top left: chert outcrop, Flint Hills; brachiopods commonly found in Kansas rocks; Cottonwood Limestone fence ...The Chautauqua Hills region—averaging just 10 miles in width—is a sliver of sandstone-capped rolling hills that splits the Osage Cuestas region from the southern Kansas border up to Yates Center in Woodson County. Small patches of similar terrain can be found as far north as Leavenworth County. During the Pennsylvanian subperiod, about 299 million to …The surface of the Wellington-McPherson Lowlands region of south-central Kansas is mainly a relatively flat to rolling alluvial plain, made up of unconsolidated sand, silt, and gravel. The region is dissected by the Arkansas River Lowlands region, which encompasses the Arkansas River floodplain. Within the Wellington-McPherson Lowlands, the ...Schermerhorn Cave within the park boundaries is one of numerous Mississippian limestone caves in the region. It can be reached by way of a fairly level walkway from the park's Nature Center. The spring issuing from the cave is home to the Long-tailed Salamander, Cave Salamander, and Grotto Salamander. When conditions are cool and damp, they ...The surface of the Arkansas River Lowlands is a relatively flat alluvial plain made up of sand, gravel, and other sediment deposited by a meandering Arkansas River. Over the last 10 million years, the river has flowed into the state from high in the Rockies, where its source is fed by runoff from rain and snowmelt. Very little water is added to ...Salt is mined in Kansas using two methods: underground mining and solution mining. Underground mines in Kansas range in depth from 500 to 1,000 feet. With the underground room-and-pillar method of mining, a shaft is drilled through overlying rock to reach the salt deposit. The salt is removed in a checkerboard pattern so that large square ...Oolite is a type of sedimentary rock, usually limestone, made up of ooids cemented together.An ooid is a small spherical grain that forms when a particle of sand or other nucleus is coated with concentric layers of …Chert. Commonly known as flint, chert is found in many Kansas limestones as nodules or continuous beds. It is a sedimentary rock composed of microscopic crystals of quartz (silica, SiO 2 ). It is opaque and ranges in color from white to dull gray or brown to black. Chert breaks with a shell-like ( conchoidal) fracture, and the edges of the ...Ammonoids were squidlike creatures that lived inside an external shell. In fact, ammonoids are relatives of the modern squid, as well as the octopus and chambered Nautilus, all of which belong to the class of animals called cephalopods. Two ammonoids from Pennsylvanian rocks in southeastern Kansas. The top specimen (from the Eudora Shale Member ...Sometimes, the sediment is cemented by minerals and other materials. Common sediments in Kansas: S and— rock fragments or mineral particles that range in diameter from about 1/16 to 2 mm (from 0.002 to 0.08 inches). Gravel —chipped or rounded rock fragments that typically range in diameter from about 3 to 75 mm (0.125 to 3 inches). Bordering the Spring River in Cherokee County, the Spring River Wildlife Area falls just within the Ozark Plateau region.

They are also widespread today, both in marine and freshwater environments, living at all latitudes and at depths ranging downward to at least 27,900 feet (8,500 meters). Marine bryozoans show up in the fossil record in the early part of the Ordovician Period, about 485 million years ... The KGS county geologic mapping program makes basic geologic information about the state available to the public. Topographic maps produced by the U.S. Geological Survey show natural and manmade features on the surface as well as elevation contours. Topographic maps of Kansas in varying levels of detail are available from the KGS.Geodes are crystal-lined cavities in rocks. The crystals are formed when minerals precipitate (settle) out of groundwater in underground rock cavities.. The minerals deposited may vary, but in Kansas most geodes consist of quartz, chalcedony (a type of quartz), and calcite.They commonly form in limestone and can be found in many places in the Flint …Kansas is defined by being a centrally located state. Flat expanses, badlands, rolling hills, cuestas, and canyons shape Kansas’ geography. Kansas is a state of wheat farms, ranching, and wind turbines. From military installations to airplane manufacturing, geography has shaped and continues to shape Kansas.Clams and their relatives (oysters, scallops, and mussels) are often called bivalves (or bivalved mollusks) because their shell is composed of two parts called valves. Bivalves have a long history. Their fossils first appear in rocks that date to the middle of the Cambrian Period, about 510 million years ago. Fossils in Kansas. Fossils specimens: Delocrinus, Acanthoceras, Meganeuropsis. Many Kansas rocks are full of fossils, the remains of plants or animals that have been preserved in rock. Through fossil finds, geologists and paleontologists piece together evidence of earlier life and landscapes on Earth.Monument Rocks are composed of the Smoky Hill Chalk Member of the Niobrara Chalk. Despite its name, the Niobrara Chalk is a geologic formation made up mainly but not entirely of chalk, and the layers at Monument Rocks include chalky limestone and chalky shale. The chalk beds first became famous in the 19th century for fossils of giant swimming ...2 Images.

The epicenter was in Sumner County near Milan, where some buildings suffered minor damage. At least 31 felt earthquakes in Kansas were documented in newspaper accounts and other sources between 1867 and 1976. Ozark Plateau. The Ozark Plateau region is the smallest in Kansas, covering just 55 square miles in the southeastern tip of Cherokee County and the state. It is, however, part of the much larger regional Ozark Plateau that extends tens of thousands of square miles into Missouri, Oklahoma, and Arkansas. In Kansas, the Ozark Plateau region is ...Fusulinids. Fusulinids were small marine organisms that were common inhabitants of the world's seas during the Pennsylvanian and Permian periods, from about 323 to 252 million years ago. The earliest fusulinids occur in rocks deposited during the late Mississippian Period, more than 323 million years ago. Fusulinids became extinct during the ...Loess is a finely ground silt that is deposited by the wind. In the High Plains of Kansas, loess was deposited by the wind during the Ice Ages of the past million years. This finely ground silt was formed as glaciers advanced over the continent, pulverizing rocks and sediments in their path. When the glaciers melted, this silt was deposited on ... Geologic time: A metaphor. Earth is at least 4.6 billion years old. Such an expanse of time is hard to grasp, but it is fundamental to understanding basic geologic processes, such as the build up and erosion of rock layers that shape and reshape Earth's surface.
