Sedimentary rock - Limestones and dolomites Britannica

Limestones and dolomites. Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO 3) and dolomite (CaMg[CO 3] 2).Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process continue to be debated.

Limestone and dolomite - Earth Resources

Younger limestones tend to be friable and porous, whereas older limestones are often dolomitised and silicified, or metamorphosed and recrystallised to marble. Victorian Palaeozoic limestones and dolomites were formed in marine settings, whereas Tertiary limestones were formed in a range of subaqueous and subaerial environments. Limestone uses

Soft and easily weathered creamy yellow magnesian limestones (dolomites) and sands form gently rounded, convex slopes. They are overlain in places by boulder clays, or locally by glacial sands and gravels that give rise to a more undulating terrain. There are occasional steep-sided glacial melt water channels that cut down into valley floors or breach the escarpment ridge. Valleys are often ...

Limestone - Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

The dolomites are calcian with an elemental composition of approximately (Ca55, Mg45)Co3. The Sr content averages 500 ppm Sr, whereas the Mn and Fe contents are relatively low, c. 200 ppm Mn and 2000-4000 ppm total Fe respectively. The oxygen and carbon isotope values (-2.3%o to -3.9%o 6lsO; +1.9%> to +4.6%o 813C) are close to the field of early diagenetic dolomite replacing marine limestones ...

Stromatolitic dolomites in the late precambrian

01/01/1978  The dolomites are usually thick, light in colour, and locally contain reef complexes and stromatolites, while the limestones are usually thinner, more argillaceous and dark through bitumi- nous matter. A similar lateral increase in the Mg content of the limestones as the basin edge is approached was observed by Germs (1972) in the lime- stones of the Nama Group of southern South West Africa ...
