Abstract Calcite grains from 19 composite dolomite-calcite marble samples from the Marmorilik Formation, West Greenland, have been analysed for Ca, Mg, and Fe with the microprobe in order to estimate metamorphic temperatures using the calcite-dolomite solvus geothermometer. The results show that there are large variations within single samples, and, insofar as any thermal gradient can be detected, it is the opposite of that indicated by mineral parageneses. Current practice in the application of the method is therefore questioned.
