Feb 18, 2021 · Mineralogy: Octocoral sclerites are all composed of CaCO 3 in the form of high-magnesium calcite. More detailed compositional analyses have been obtained for the sclerites of Mediterranean gorgonians and precious corals. In the former, magnesium concentrations ranged between 1.4 and 2.2% (Weinbauer and Vellmirov, 1995).Slightly higher values (2.1–3.0%) …
