Limestone

2021-12-27 · Limestone, or calcium carbonate, is the common rock found throughout the world. Oldest and perhaps slightly overlooked, limestone is very much part of our everyday life. It may be hidden with your walls, in the water you drink, the food you consume, or in the cosmetics.

Processes of Chemical Weathering

2021-8-24 · 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.

2018-6-12 · There are different types of chemical weathering, the most important are: Solution - removal of rock in solution by acidic rainwater. In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts.
