A summary of elemental and isotopic compositions of the Mesozoic gabbros and Cenozoic basalts from the Taihang Mountains shows a remarkable difference in their mantle sources.
Combining the results with the dataset of UHP ecologites from Dabieshan, the high H_2O character of the Shacun gabbros suggests that the subducted eclogites could be involved in the source.
