Luliang meta-gabbro whole rock geochemistry and zircon isotope and trace elements data

Recognition of tectonic switching is of great significance for understanding the formation and evolution of ancient accretionary orogens. In this study, whole-rock geochemical and Sm-Nd isotopic, and zircon U-Pb, Lu-Hf isotopic and trace element data are reported for two generations of metamorphosed mafic rocks from the Lüliang Complex, middle Trans-North China Orogen (TNCO).
