Abstract:
Carbonate formation are discussed from all published mineral compositions and the X-ray fluorescence (XRF) analyses with contents of carbon and other foreign elements. New formation of metamorphic calcite minerals are discussed by these elements with the XRF data of present sea-shells, transparent calcite crystal and aragonite, and coloured calcites (grey, red and green) and marble-stones of European and Middle-East countries used for wall-stones. Mineral characteristics of these foreign elements of Na, Mg, Al, Si, P, S, Cl, K and Fe, replaced in Ca and C, in calcite-carbonates are considered to be new indicator of these formations at their circumstances (such as sea-floor or sea-surface, rocks of plate-tectonics or meteoritic metamorphism at the crustal rocks).
