  • Carbonate Facies - SEPM Strata

    Collectively studies have shown that carbonate facies are commonly the product of processes that are active in their depositional setting. Water depth, winds, waves, currents, temperature, water chemistry, and biologic action all affect the character of the carbonate formed. Diagenesis, which also plays a major role in forming and modifying the facies that are found in the subsurface, are ...

  • Carbonate-rock aquifers text.gov

    The water-yielding properties of carbonate rocks are highly variable; some yield almost no water and are considered to be confining units, whereas others are among the most productive aquifers known. Most carbonate rocks form from calcareous deposits that accumulate in marine environments ranging from tidal flats to reefs to deep ocean basins.

  • Carbonate Sedimentary Rock Classification

    Because all these rocks have CO 3 - - in common they are called the carbonates. The composition of most carbonates is derived from a combination of biological and chemical components. Two carbonate classification systems are in common use today, one by R.L. Folk and the second by R.J. Dunham .

  • Carbonate diagenesis - AAPG Wiki

    There are five basic carbonate depositional environments. From shore to basin, they are peritidal (tidal flat), shallow shelf interior, shelf margin complex, slope, and basin . (For more information on carbonate depositional environments, see Scholle et al.) The peritidal depositional environment is complex .

  • Carbonate reservoir - AAPG Wiki

    There are some similarities to siliciclastic environments. Various sedimentary bodies such as beaches, barrier islands, shelf sediments, gravity flows, and dune sands are also found in carbonate settings. Many carbonate reservoirs offer a challenge to the production geologist. Carbonate reservoirs can be difficult to develop for a variety of ...

    Carbonate environments have changed substantially over geological time by comparison to siliciclastic environments; for example, the type of organism responsible for building reefs has varied throughout the geological record. For this reason, it is advisable to select an outcrop analog that was deposited at roughly the same time as the ...

  • The "Acid Test" for Carbonate Minerals and Carbonate Rocks

    The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them. Limestone is composed almost entirely of calcite and will produce a vigorous fizz with a drop of hydrochloric acid. Dolostone is a rock composed of almost entirely of dolomite. It will produce a ...

  • GEOL342 - Sedimentation and Stratigraphy

    Because many carbonate allochems behave hydrodynamically like sand, most of the sedimentary structures we associate with clastic shorelines are found in peritidal carbonate environments, with some odd twists: Because of their shoaling upward tendency, carbonate banks can present topographic profiles that may cause waves to break farther from shore.

Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO3). Dolomites are mainly produced by the secondary alteration or replacement of limestones; i ...

    Carbonate environments occur both in the terrestrial and marine realms as well as in transitional zones between the land and the sea. The variety of environments spans from high-elevation continental lakes to the deep sea, from the equator to latitudes of about 60°, and they include dry and wet climate realms.

    Carbonate rock. Carbonate rocks are a class of sedimentary rocks composed primarily of carbonate minerals. The two major types are limestone, which is composed of calcite or aragonite (different crystal forms of CaCO 3) and dolostone, which is composed of the mineral dolomite (CaMg(CO 3) .

    Carbonate minerals are compounds made with the carbonate ion (CO 3 2-). While many minerals can form in that way, only two are common enough in sedimentary environments and in the rock record to be worth mentioning: calcite and dolomite. Carbonate rocks composed of calcite (CaCO 3) are called limestones while carbonate
