The lower crustal rock samples are collected from Qinghai-Tibet Plateau orogen, Kohistan arc, and North China Craton. Whole-rock major and trace elemental compositions were analyzed at the Institute of Geochemistry, Chinese Academy of Sciences (IGCAS), Guiyang. The major element contents of all the samples were determined on glass discs using a Philips PW2400 X-ray fluorescence (XRF) spectrometer.Whole-rock trace element contents were determined using a PerkinElmer DRC-eICP-MS. Cu isotope analyses were performed at the Metal Stable Isotope Laboratory of the University of Science and Technology of China (USTC).Cu isotope ratios were measured on a Thermo-Fisher Neptune Plus MC-ICP-MS, and the sample standard (NIST 976) bracketing method was used for mass bias correction.
