The interpretation of complexly zoned carbonate cements in terms of diagenetic fluid chemistry remains a central problem in carbonate petrology. In addition to concentric zoning induced by changes in fluid chemistry, synthetic and natural calcite crystals commonly display compositional differences between (1) time-equivalent growth sectors that grew on nonequivalent faces (sectoral zoning), and (2) time-equivalent portions within single growth sectors (intrasectoral zoning). The combination of… CONTINUE READING
