International audience An analytical procedure has been developed for the in situ measurement of calcium isotope composition of carbonates with a spatial resolution of 15-20 μm on a Caméca IMS 1270 ion microprobe. By using two Faraday cup detectors, the 40 Ca and 44 Ca can be measured simultaneously...
