摘要

     The study indicates that the volcanic rock from the Tongkuangyu Cu deposit in Zhongtiaoshan, Shanxi Province is rich in K series of Al-saturated type with SiO₂ of 47.22~76.00%, A1203 of 11.03~20.03 %. The REE geochemistry indicates that the magma was derived from the upper mantle. The minor element geochemistry is characterized by enrichment in Rb, K, Ba and Th and depletion in Sr, Tb, Nb and Ti, which is characterized by intraplate tholeiite.
