Trace element spidergrams for MS inclusions in garnet of UHP eclogite from the Dabie orogen, China (Additional file4: Table S3). (a) Large MS inclusions have a size of 24 to 160 μm that were directly sampled by internal ablation for the LA-ICPMS analysis. (b) Small MS inclusions have a size of <24 μm that were sampled by external ablation with minor involvement of the host mineral. Black curves denote the data from Gao et al. (2013), and blue curves denote the data from Liu et al. (2013). Data for the primitive mantle are after McDonough and Sun (1995). The composition of small MS inclusions was reconstructed by minimizing the Fe content of single MS inclusions relative to the host garnet in order to achieve the accurate estimate of its volume proportion relative to the ablated host garnet. This was based on the correct identification of mineral phases in these small MS inclusions.
