Modern carbonate sediments are composed almost entirely of metastable (a different crystal form of CaCO₃) and magnesium-rich calcite , both of which readily recrystallize during diagenesis to form calcite. Other calcite group minerals such as magnesite (MgCO₃), rhodochrosite (MnCO₃), and siderite (FeCO₃) occur in limited amounts in restricted environments.
): Tracks global tectonic weathering rates versus hydrothermal mid-ocean ridge activity, aiding in the chronostratigraphic correlation of sequences lacking index fossils.
