Calcite Indiana Geological & Water Survey
A rock collector's journal featured a large, showy calcite crystal on its issue devoted to minerals and fossils of Indiana. Most crystals are clear, white, amber, or brown. Excellent crystals of Indiana calcite can be found in museums all over the United States. Calcite is also abundant in Indiana's geodes. Perfect crystals of many shapes and
Concretion Wikipedia
A concretion is a hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word 'concretion' is derived from the Latin con meaning 'together' and crescere meaning 'to grow'.

CALCITE FOR SALE. Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. The other polymorphs are the minerals aragonite and vaterite. Calcite crystals are trigonal-rhombohedral, though actual calcite rhombohedra are rare as natural crystals. However, they show a remarkable variety of habits including acute to obtuse rhombohedra, tabular forms, and prisms. Calcite

Sedimentary rock Limestones and dolomites Britannica
Sedimentary rock Sedimentary rock Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process
Dolomite Rock Sedimentary Rocks
Dolomite or dolostone is a carbonate sedimentary rock containing more than 50% by weight of the mineral dolomite.Dolomite rock may contain calcite, but the content of calcite should not exceed 10% of the calcite-dolomite pair’s content 3.. Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.
Belemnites Fossil Focus British Geological Survey (BGS)
Belemnites also give their name to 20-plus metres of Jurassic rocks on the coast of Dorset. These are the Belemnite Marls, of Pliensbachian age, which can be seen in the cliffs near Charmouth. Belemnites are the best preserved fossils in this interval, and include the genera Angeloteuthis, Bairstowius, Hastites, Passaloteuthis and Pseudohastites.
Calcite Mineral Uses and Properties

Fossil Wikipedia
A derived, reworked or remanié fossil is a fossil found in rock that accumulated significantly later than when the fossilized animal or plant died. Reworked fossils are created by erosion exhuming (freeing) fossils from the rock formation in which they were originally deposited and their redeposition in an younger sedimentary deposit.

University of Minnesota’s Mineral Pages: Dolomite
Fossils composed of pure calcite may be less likely to be altered and may remain as calcite fossils in an otherwise dolomite rock. As calcite dissolves more easily than dolomite, such calcite fossils can later be dissolved to leave fossil molds in the dolostone rock.

Calcite is a very common Oxfordshire mineral. The limestones of Oxfordshire are composed mainly of calcite. Some are of Jurassic age, but the beds of chalk, a very pure form of limestone, are of Cretaceous age. Clay deposits in the county may contain substantial amounts of fine-grained calcite, and the shelly fossils which are abundant in most
