Abstract : Carbonate O-isotope compositions of 9 CMs define a continuous trend crossing the TFL. This mass independent trend matches that defined by bulk CM-COs and matrix (BMC trend). CM water defines a trend (CMW) parallel to the bulk-matrix-carbonate trend (BMC). The distance between BMC and CMW is directly related to CM alteration temperature. Carbonates precipitated at higher temperatures than previously inferred (50-300°C).
