From a geological perspective, the formation of limestone takes place in two different environments, sedimentation in deep marine water and water evaporation during cave formation. Marine Environment to Form Limestone. In oceans, a variety of living organisms thriving in the ecosystem. However, before life did evolve, limestone formed through an inorganic process where rain water falling through a CO2-rich atmosphere reacted to form a weak carbonic acid solution that then reacted with calcium-containing minerals to form calcites. This then washed into the world's oceans to form limestone deposits.Geology. Limestone is a common sedimentary rock that is composed mostly of the mineral calcite (CaCO3). It is produced by crystallization from water, or by accumulation of shells and shell fragments. Limestone, a sedimentary rock, is made up mainly of calcite, which is made up mainly of the skeletons of microsopic organisms.Limestone and dolostone are collectively referred to as carbonates because these two sedimentary rock types consist mainly of the minerals calcite (CaCO3 ), aragonite (CaCO 3 ), and dolomite [CaMg (CO 3) 2 ].
