(often 11–19%). It is secreted by echinoderms, bryozoans, and red algae, and is chemically unstable during diagenesis. Dolomite
Occurs under elevated temperatures and pressures. Mechanical and chemical compaction occurs, leading to pressure solution seams known as stylolites. The Phenomenon of Dolomitisation
The Origin and Formation of Carbonate Sedimentary Rocks: A Comprehensive Guide
Most modern and Phanerozoic carbonates are generated directly by living organisms. In biomineralisation, organisms actively extract Ca2+Ca raised to the 2 plus power HCO3−HCO sub 3 raised to the negative power
The "Warm Water Model" is the standard for understanding ancient carbonates. In tropical, shallow, agitated waters, CO₂ is degassed, and evaporation is high. This environment favors the precipitation of aragonite and high-magnesium calcite (HMC), which are metastable polymorphs of calcium carbonate.
Modern carbonate petrology goes far beyond a hand lens. High-quality resources like the are indispensable for advanced study. These tools teach the identification of specific grain types and diagenetic fabrics using a polarizing microscope and advanced techniques like cathodoluminescence, which reveals complex cementation histories invisible under normal light.
Microcrystalline calcite matrix (grain size
The detrital source of carbonate minerals includes the erosion of pre-existing carbonate rocks, such as limestone and dolostone. These rocks can be transported and deposited as detrital sediment.
Dissolved ions reprecipitate as stable low-magnesium calcite, generating blocky spar cements and syntaxial overgrowths. 3. The Deep Burial Realm
The characteristics of a carbonate rock are a direct reflection of the environment in which it formed. These rocks are incredibly sensitive to depth, light, water energy, and salinity. Understanding these depositional systems is the key to interpreting ancient rock records.
