Chalk, a sedimentary rock, is a soft form of limestone that is not well cemented and thus is often powdery and brittle. It usually ranges in color from white to light gray to buff and forms from sediment deposited in a saltwater environment. Composed mostly of the mineral calcite and formed mainly from the remains of floating microorganisms and ...The Oread Limestone, a formation common in eastern Kansas, was named in 1894 by Erasmus Haworth, the first director of the Kansas Geological Survey. He named it after Mount Oread, the hill on which the University of Kansas is located and where the limestone cropped out. The Dakota Formation, a familiar rock unit in central Kansas, got its name ... Dolomite. The mineral dolomite is the main component of the sedimentary rock that is also called dolomite. It is similar to the mineral calcite but contains magnesium as well as calcium. Just based on looks, the rock dolomite is often impossible to distinguish from limestone, which is composed mainly of calcite. Dolomite crystals are usually ...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.

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 ...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 ...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.

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.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 ...

Concretions are masses of mineral matter embedded within rock layers, including limestone, sandstone, and shale. They often take shape when minerals precipitating (settling) out of water collect around a nucleus, such as a pebble, leaf, shell, bone, or fossil. Concretions most often form in sediment before or as the sediment is ...

One method is based on magnitude—the amount of energy released at the earthquake source. The other is based on intensity—how much the ground shakes at a specific location. Although several scales have been developed over the years, the two commonly used today in the United States are the moment magnitude scale, which measures magnitude (M ...

Landslides. A 1995 landslide in Overland Park, Kansas, destroyed two homes and damaged four lots. Landslides, though not a common problem in Kansas, are natural phenomena that occurred in the state long before human occupation. The downhill movement of masses of soil and rock come in many forms and are potentially serious. 4 Images. View Gallery. Tallgrass Prairie National Preserve is the only unit in the U.S. National Park System devoted to North America's tallgrass prairie ecosystem, which once covered 170 million acres from Kansas to Indiana and Canada to Texas. Less than 4 percent of the natural prairie remains today, most in the Kansas Flint Hills. 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. South-central Kansas—a mix of the Smoky Hills, Arkansas River Lowlands, Red Hills, High Plains, and Wellington-McPherson Lowlands physiographic regions—includes a transition zone between lush eastern prairie and the arid grasslands of the western prairie.

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.

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. The 1,123-acre area has 14 miles of hiking, interpretive, and horseback riding trails that loop through sand dunes, grasslands, marshlands (with wildlife observation ...The largest Kansas earthquake in recent years was a M 4.9 event in 2014 that was thought to have been caused by induced seismicity. 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. 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. To make geologic time easier to comprehend, geologists divided the 4.6 billion years of Earth’s history into units of time called eons. Then they further divided the eons into two or more eras, eras into two or more periods, periods into two or more epochs, and epochs into two or more ages. These units are called geochronologic units, (geo ...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. The Smoky Hills region in north-central Kansas encompasses a range of hills composed largely of sandstone, a second composed largely of limestone, and a third composed largely of chalk. Although visibly different, they are unified by age—all were formed from sediment deposited during the Cretaceous Period, which lasted from 145 to 66 million ... Bordering the Spring River in Cherokee County, the Spring River Wildlife Area falls just within the Ozark Plateau region.
