Kimberlite is one of only two igneous rocks found at the surface in Kansas. Extremely rare in the state, igneous rocks form from hot molten magma that pushes up toward the surface from Earth's interior then cools. The magma may cool and harden before reaching the surface or erupt onto the surface. Kimberlite forms in vertical structures in the ...Kansas DRG Maps. View the entire list of USGS Kansas Digital Raster Graphic Maps.Gypsum. A common mineral in Kansas, gypsum is calcium sulfate with two molecules of water (CaSO 4 •2H 2 O). Calcium sulfate without water is the mineral anhydrite (CaSO 4 ). It is colorless or white to light gray (or, rarely, bright red) and is so soft that it can be scratched by a fingernail. Gypsum is divided into three varieties.Learn more about earthquakes, sinkholes, landslides, and environmental issues facing Kansas today and the KGS role in addressing them.

Dinosaurs appeared and disappeared during the Mesozoic Era, which lasted 186 million years and encompasses three periods: the Cretaceous, Jurassic, and Triassic. During the first part of the era, much of the surface in Kansas was being eroded. If dinosaurs lived in Kansas then, they weren't preserved. Later, seas covered much of the state. Vertebrate fossils—of gliding reptiles that dominated the sky, of sharks and swimming reptiles that ruled the sea, of dinosaurs and mammoths that roamed the land—are embedded in Kansas rocks and sediments. Some are common in specific locations. Others, such as dinosaurs, are rare. Several types of sharks and fish lived in the Pennsylvanian ... Bryozoans are some of the most abundant fossils in the world. 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 ...

An unexpected strip of ravines and canyons, the Arikaree Breaks region in the northwestern tip of Kansas stands out in sharp contrast to the surrounding plain. The rugged canyonland, just two to three miles wide, cuts diagonally across northern Cheyenne County and stretches just across the state line west into Colorado and north into Nebraska ...Explore Southwest Kansas. The High Plains of southwest Kansas, bisected by part of the Arkansas River Lowlands, are known for farmland and feedlots. But geologic sites of interest include two large sinkholes, a high outcrop once important to travelers on the Santa Fe Trail's Cimarron Cutoff because it signaled water was nearby, and an area once ...

Rock City. Huge sandstone spheres ranging up to 20 feet in diameter cover an area roughly the size of two football fields at Rock City, about four miles south of Minneapolis in Ottawa County. Known as concretions, the spheres weathered out of a sandstone layer in the Dakota Formation. The sandstone was formed mainly from sand deposited along ... The Kansas Geological Survey (KGS), a research and service division of the University of Kansas, is charged by statute with studying and providing information on the geologic resources of Kansas.The KGS has no regulatory authority and does not take positions on natural resource issues. Research at the KGS focuses primarily on energy, water, and the environment and addresses natural resource ...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 ...

One of the most common rocks in Kansas, limestone is a sedimentary rock composed mainly of the mineral calcite, which is a calcium carbonate. Most limestone layers formed from marine sediment deposited on sea floors, although some formed in freshwater lakes and rivers and even on dry land. Sources for the calcite in limestone include seashells.

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. If you squeezed all of Earth's history into one calendar year, the first 4 billion ...Point of Rocks is west off of Kansas Highway 27 about 10 miles north of Elkhart. It is in the Cimarron National Grassland managed by the U.S. Forest Service. The grassland encompasses more than 108,000 acres of land left in poor condition after the Dust Bowl of the 1930s and restored by the federal government. Wagon ruts are visible in places.Most sinkholes in central Kansas, whether natural or related to human activities, are the result of dissolution of halite (rock salt) by groundwater in the Hutchinson Salt Member. That thick salt bed—about 350 feet thick and 400 feet deep in the Hutchinson area—formed from deposits of salt and other sediment left behind when a shallow sea covering the area receded about 252 million years ...The 10-acre park in Wyandotte County offers a sweeping view of the rivers and the surrounding urban landscape, including the Kansas City, Missouri, skyline and the visible line where the darker water of the Kaw meets the lighter-brown Missouri. Trails, picnic areas, a boat ramp and docking area, and an outdoor amphitheater are among the ...The Kansas High Plains region is an area of vast flatlands and gently rolling plains. Topographic relief is largely restricted to streams and river valleys and is most notable in the Arikaree Breaks in the far northeast corner of the state, at Point of Rocks along the Cimarron River in the far southwest corner, and around Lake Scott State Park.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 …Water in Kansas. In most years, precipitation in the form of rain, sleet, or snow is greatest in eastern Kansas and gradually declines toward the west. The wettest spot, on average, gets 45 inches per year and the driest less than 20 inches. As a result, eastern Kansas has more surface water — rivers, creeks, lakes, and wetlands.

Another catastrophic collapse—known as the Cargill sinkhole because of its proximity to the Cargill Salt company—left railroad tracks dangling precariously in midair and grew to 200 feet in diameter in just 14 hours in 1974. Three weeks later, the diameter stabilized at 300 feet. The KGS uses seismic reflection techniques to study sinkholes. Big Basin. Big Basin is a large circular depression about one mile across and 100 feet deep that is bisected by U.S. Highway 283/160. Based on the age of the rocks in its walls, geologists estimate the basin formed fairly recently (in geologic time, that is), probably within the last few thousand years. The floor of the basin, about 125 to 150 ...

One of the best places in the state to access sand dunes on public property is Sand Hills State Park in the Arkansas River Lowlands just northeast of Hutchinson in Reno County.

They vary widely in shape and size, with the huge spherical concretions at Rock City in Ottawa County and Mushroom Rock State Park in Ellsworth County measuring up to 27 feet in diameter. A special type of concretion, known ...Oolite. 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 calcite or other minerals. Ooids most often form in shallow, wave-agitated marine water. Just as oolitic limestones form ...Coal (which consists chiefly of carbon compounds derived from plants and plant debris that have been compacted into firm, brittle rocks) occurs throughout the Osage Cuestas. It was extensively mined in Osage County. Between 1885 and 1892, Osage County had 118 coal mines, which employed more than 2,200 people and produced almost 400,000 tons of ...Mapping across Kansas.

Winding along both sides of Deep Creek, the 59-acre Pillsbury Crossing Wildlife Area includes a short trail that follows the creek through oak and hackberry riparian (riverbank) forest. A cliff on the northwest side of the river by the waterfall is the six- to nine-inch-thick Elmont Limestone Member of the Emporia Limestone formation.The Crawford sinkhole, which causes Interstate 70 to sag west of Russell, has been linked to an improperly plugged and abandoned oil well. Because the well was not adequately sealed, groundwater leaked along the well casing into the Hutchinson Salt Member about 1,300 feet below the surface. An underground void was created where the salt ...Sinkholes, also called sinks, develop slowly when the ground subsides a few inches a year or catastrophically when the surface drops tens of feet per second. A common instigator is groundwater that dissolves a sizable hole in an underground layer of halite (rock salt), gypsum, or other evaporite. If a void becomes so large that the evaporite ...Based on common landscape features and geological history, geologists have divided Kansas into the 11 different regions shown on the map.
