Five types of dolostones with fabric-retentive and fabric-destructive textures are recognized within the oolitic shoals on the eastern side of the K-L Trough ...Oolitic. A limestone texture that is characterized by spherical grains of calcium carbonate with a concentric internal structure. These grains are thought to form by inorganic precipitation of calcium carbonate around a sand grain or shell particle nucleus. Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. During metamorphism the calcite limestone recrystallizes, forming the interlocking calcite crystals that make u...Dolomitic limestone is a type of rock that includes up to 50% dolomite.Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization. This type of rock was once referred to as magnesian …Dolomitic limestone contains between. 10 and 45% magnesium carbonate, is somewhat crystalline in form, and has a greater variety of texture.

Oolitic limestones are a type of sedimentary rock that are primarily composed of calcium carbonate (CaCO3) and small, spherical grains known as ooids. Ooids are typically 0.25mm to 2mm in diameter and are formed from concentric layers of calcium carbonate that build up around a central nucleus, such as a shell fragment or a grain of sand.

Composition Ooids are most commonly composed of calcium carbonate ( calcite or aragonite ), but can be composed of phosphate, clays, chert, dolomite or iron minerals, including hematite. Dolomitic and chert ooids are most likely the result of the replacement of the original texture in limestone.

Limestone wears better than sandstone, is more easily shaped than granite, and weathers from nearly white to a beautiful gray. Oolitic limestone, quarried in Lawrence, Monroe, and Owen counties in Indiana, is a particularly fine building stone. Its texture resembles fish eggs—hence its name, from the Greek oion, meaning “egg.” Bedford ...

Oölite, ovoid or spherical crystalline deposit with a concentric or radial structure; most are composed of calcium carbonate, but some are composed of silica, siderite, calcium phosphate, iron silicate, or iron oxide. Oölite diameters range from 0.25 to 2 mm (0.01 to 0.08 inch), with most being in

Calcarenite is a clastic limestone consisting predominantly of sand-grade (1/16 to 2mm in diameter) calcitic or aragonitic particles (allochems, Folk, 1959 ); it is a consolidated carbonate sand. Grabau (1904) introduced this term as calcarenyte in his genetic classification of sedimentary rocks to convey the basic calcareous ... Article Oolitic Limestone is made up of small spheres called ooiliths that are stuck together by lime mud. They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow seafloor. Oolite or oölite (egg stone) is a sedimentary rock formed from ooids, spherical grains composed of concentric layers.Classifying the Rock Types Rocks composed of ooids of a larger than 2 mm diameter are called pisolites (made up of spherical shapes called pisoids).
