Carbonates & Other Rocks

From the figure shown here, one can see that the average sandstone and mudrock have similar proportions of analogous constituents to average sparry (crystalline) limestones and micritic (fine grained crystalline limestones. This suggests a similarity of processes involved in the formation of clastic sediments and carbonate rocks.

Lime Production from Limestone | Grade 12U Chemistry ...

May 07, 2013· An application of a chemical equilibrium for an industrial system is lime production from limestone. The products which are made from burnt limestone are called lime (ie. quicklime and hydrated lime). Limestone is naturally occurring, and it also consits of minerals in small pieces. Presently, limestone products are used as a crucial part in most industrial processes.

Limestone: Rock Uses, Formation, Composition, Pictures

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.

Processes of Chemical Weathering - CliffsNotes

Solution weathering is the process by which certain minerals are dissolved by acidic solutions. For example, calcite in limestone is dissolved easily by carbonic acid. Rain that percolates through cracks and fissures in limestone beds dissolves calcite, making wider cracks that can ultimately develop into cave systems. Oxygen.
