Minor and trace element abundances of diopsides (Na, Mn, Ti, Al, Sr, Zr, Cr,Ni, Zn, Cu, Nb, Ba, etc.) and olivines (Ca, Mn, Ti, Zn, Ni, etc.) from spinel lherzolites from Panshishan Neogene alkalic basaltic volcanic rock, Luhe, Jiangsu Province, China analysed by proton microprobe (PMP) are reported here. Combining PMP data and mineral chemistry (by EMP) and major, minor and trace element data (by XRF) of whole rock of spinel lherzolites, the quantitative distribution of trace elements between mineral phases in mantle peridotites are discussed. Olivine and diopside are the main host mineral phase for trace element Ni, Mn and Zn and Ca.Sr.Ti and Na, respectively. The partitioning coefficients of Ti, Mn, Ni, Zn between olivine and diopside in different equilibrium temperatures (1200-1450K) are calculated. They are as function of temperature in form of van’t Hoff’s law- The behaviors of trace elements during cryptic metasomatism of continental lithospheric mantle under the area are deduced.
