Corrections from the Fox Hills Formation Trail City Member
Abstract
dc:description.abstract<p>Concretions occur as fairly continuous horizons in the Trail City Member of the Fox Hills Formation. These horizons are used as stratigraphic markers for correlation of the formation. </p><p>Two general types of concretions are found. The first is sandstone which occurs either as spherical or lenticular shaped forms. The other type has a hard blue-gray limestone core and is usually spherical in shape. Although both types may contain fossils, the unfossiliferous concretion is more abundant. </p><p>The concretions were formed either by accretion of material from the sediment, and from connate and ground waters; or by rolling, in the same manner as an armored mud ball form.</p>
