WebThe sum of all changes that occur to sediment and rock after burial is known as diagenesis. Depending on the diagenetic environment, sedimentary rocks can display various degrees of lithification. Some sedimentary rocks in east Texas are barely lithified; but the well-cemented limestones from Central Texas can be used as building materials. WebApr 6, 2024 · Three major geologic stages determine the porosity of carbonate rocks: [1] Predepositional. Depositional. Postdepositional. The predepositional stage is the time from when sedimentary material first forms to when it is finally deposited. Porosity created during the predepositional stage is mainly chambers or cell structures of skeletal grains ...
