The four most common carbonate minerals are calcite, aragonite, dolomite, and siderite - all of them form under specific environmental conditions. Calcite and aragonite are pseudomorphs; calcareous organisms have changed what form they prefer through geologic time in response to the amount of dissolved magnesium in the ocean.

Evaporites are composed of a variety of minerals, but gypsum, anhydrite, halite, K and Mg salts are the most abundant. Evaporite minerals form in a predictable sequence related to brine chemistry. Thick evaporite deposits occur in basins where continued influx of waters enriched in dissolved materials. Differential loading can cause evaporites to flow and deform.

Distinctive carbonate facies can be used to recognize a spectrum of environments that include peritidal areas, lagoons, shoals, reefs, ramps, slopes, and deep marine settings.

The exogenic processes of weathering and erosion create the raw materials for sedimentary rocks.

Beyond being potentially visually striking features, these structures record processes such as the precipitation of minerals, dissolution, surface processes, and bioturbation.

Specifically, this means that warm, shallow, agitated conditions tend to be most favorable for carbonate deposition. Additional influences include the activity of organisms, the amount of light, salinity, and clastic sediment input.
