Cementation (geology) - Wikipedia

Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains. The new pore-filling minerals forms "bridges" between original sediment grains, thereby binding them together. In this way sand becomes "sandstone", and gravel becomes "conglomerate" or "breccia". Cementation occurs as part of the diagenesis or lithification of

Calcination - Wikipedia

Calcination refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances. However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition. The root of the word calcination refers to its

Morphological Investigation of Calcium Carbonate during

In the formation process of calcium carbonate, calcite is the stable crystal polymorph. Thus, the crystal grows into the prism shaped calcite without additives. Sphere is shaped since the ions have different effects in the electrolyte or the additives have large steric effect to deter the growth of calcium carbonate crystal.

An example of such a special property is the effervescent reaction of calcite to a weak solution of hydrochloric acid (5% HCl). Calcite fizzes or effervesces as the HCl solution dissolves it and creates CO 2 gas. Calcite is easy to identify even without testing the reaction to HCl, by its hardness, luster and cleavage.

Testing Methods for Reconstruction of Degree of Calcite

Reconstruction of changes in deep-sea calcite saturation is key to testing proposed mechanisms for changing atmospheric CO2 content on the glacial/interglacial timescale. The reconstruction has been hampered by difficulty in finding adequate quantitative proxies for calcite dissolution at the seabed.
