Marine limestone

Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.

It makes up about ten percent of the total volume of all sedimentary rocks. A unique feature of this rock is that its main constituent, calcite, is produced chiefly by shell-producing and coral-building living organisms. The study area contains Pleistocene and middle Miocene marine limestone aquifers. Based on lithology and microfacies analysis, the middle Miocene aquifer is subdivided into two water-bearing zones.
