Mantle compositional-spatial variations caused by oblique subduction of calcium carbonate: Insights from decoupled Ca-Zn isotopes of alkaline rocks
Ca-Zn isotope of alkaline rocks
Steps to reproduce
Major elements were analyzed by X-ray fluorescence at State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences (GPMR-CUG) in Wuhan. Trace elements were analyzed using an Agilent 7700x inductively coupled plasma mass spectrometer (ICP-MS) at GPMR-CUG. Ca-Zn isotopic compositions were determined by Triton TIMS and MC-ICP-MS at GPMR-CUG.
