Abstract
Using new electron and ion-microprobe analyses of 36 olivines, 9 pyroxenes, and 10 garnets included in diamonds, it is interpreted that there must be a temporal change of T or chemistry, or both, in the mantle source-lherzolitic regions of diamonds. Some of the Cr in the olivine inclusions may be divalent suggesting that the host diamond grew in a reducing environment, not typical of lherzolites, and some diamonds grew in the presence of a liquid containing H2O and CO2.
