Early marine diagenetic dolomite is a rather ble carbonate phase and has potential to act as an archive of marine porewater properties. However, the variety of early to late diagenetic dolomite phases that can coexist within a single sample can result in extensive complexity. Microporous carbonate rocks form important reservoirs with high a permeability variability depending of sedimentary, structural and diagenetic factors. Carbonates are very sensitive to fluids-rock interactions that trigger to secondary processes like cementation and dissolution leading to reservoir properties modifications.

Sedimentary rock - Sedimentary rock - Classification systems: In general, geologists have attempted to classify sedimentary rocks on a natural basis, but some schemes have genetic implications (. knowledge of origin of a particular rock type is assumed), and many classifications reflect the philosophy, training, and experience of those who propound them. No scheme has found universal acceptance, and discussion here will centre on some proposals. Noncarbonate chemical sedimentary rocks. Properties of sedimentary rocks.
Dolomite (also known as dolostone, dolomite rock or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. In old USGS publications, it was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomites or magnesium-rich limestones. Dolomite has a stoichiometric ratio of nearly equal amounts of magnesium and calcium.
The an carbonate rocks of the Geneva Basin represent potential reservoirs for geothermal . 2018) reported three different stages of dolomitization affecting these carbonate rocks, followed by dedolomitization.
The an carbonate rocks of the Geneva Basin represent potential reservoirs for geothermal energy exploitation. The present study focuses on the geochemical characterization of these stages based on O, C and Sr isotopes of dolomites and dedolomites. The oxygen isotopic values of early dolomite are depleted compared to the values of Late Jurassic marine cements. This is interpreted to reflect dolomite precipitation from an oxygen-enriched fluid, likely evaporitic.

Dolomitization is the most striking diagenetic process affecting the late Middle Eocene shelly limestone beds at Abu Roash and its neighboring areas. Petrographic investigations reveal that these rocks represent shelly-wackstone to packstone microfacies, that they were deposited probably within a shallow subtidal setting. The rock matrix has been subjected to both selective and complete dolomitization and replaced by equigranular mosaics of fine-to medium-grained dolomite (crystalline planar-s dolomite texture).
