Concreations rocks

concretion: [noun] something concreted: such as. a hard usually inorganic mass (such as a bezoar or tophus) formed in a living body. a mass of mineral matter found generally in rock of a composition different from its own and produced by deposition from aqueous solution in the rock. .

An ironstone (76) is a sedimentary rock that contains more than 15% iron, which may be present as variable proportions of iron-bearing minerals such as goethite, siderite, and berthierine. Sedimentary ironstones may be hard and calcareous and contain quartz grains, ooliths, pebbles, and a wide variety of macrofossils. They are used for building ...In addition to rocks and minerals, Kansas has a number of other formations that are best labeled "sedimentary structures." These formations, although composed of Kansas rocks and minerals, require additional explanation. Some, such as concretions or cone-in-cone, may be mistaken for fossils. Others, such as geodes, can be spectacularly beautiful.Fossils are the traces or remains of organisms buried and preserved in sediments. They consist not only of hard body parts, such as bone and shell, but also may be impressions of plants, or tracks, trails, and burrows. Fossils can tell us what life was like on Earth in ancient geologic time, helping geologists describe ancient depositional environments and understand past climates. Fossils ...
