Robert Dunham’s system prioritizes the depositional texture and structural fabric of the rock, assessing whether the grains were self-supporting during deposition or supported by a mud matrix.

The Bahamas is the classic modern analogue for understanding carbonate systems. The shallow Great Bahama Bank is a massive, rimmed carbonate platform where ooids form in high-energy tidal deltas, whitings (suspended carbonate mud) precipitate from the water column, and stromatolites grow in hypersaline lagoons. Studying modern environments like this allows geologists to interpret the complex facies patterns seen in the rock record. ions prevents easy incorporation into a structured lattice

Original components bound together during deposition (e.g., coral reefs). Folk Classification System (1959)

Origin of Carbonate Sedimentary Rocks: A Comprehensive Overview Carbonate sedimentary rocks, including limestone ( CaCO3CaCO sub 3 ) and dolostone ( The shallow Great Bahama Bank is a massive,

Vast, shallow epicontinental seas common in Earth's past (e.g., during the Ordovician or Cretaceous) that allowed uniform carbonate blankets to form over thousands of square kilometers. Deep Marine Settings

) into its crystal lattice due to its open atomic structure. A trigonal polymorph of CaCO3CaCO sub 3 . It is further categorized based on its magnesium content: Low-Magnesium Calcite (LMC): Contains less than 4 mol% MgCO3MgCO sub 3 . It is highly stable. High-Magnesium Calcite (HMC): Contains more than 4 mol% MgCO3MgCO sub 3

The widespread presence of massive dolomite formations in the ancient rock record contrasts sharply with its scarcity in modern marine environments—a paradox termed "The Dolomite Problem."
