| 英文摘要 | The field observation, petrology, geochemical features and age of the lamprophyres in Kuda, western Kunlun are presented in this paper. The lamprophyres occur as dikes emplaced in Caledonian metamorphic accretionary complex with the wall rocks of muscovite-quartz schist and felsic gneiss. The emplacement age of lamprophyres is 404Ma determined by hornblende Ar-40/Ar-39 dating method. The lamprophyres are characteristed as calc-alklic kalicamptonite. The total REE and the LREE/HREE ratio of lamprophyres are up to ca. 180 and 3.0, respectively. Also, it is relatively rich in LILE and depleted in HFSE. Based on the analysis of geochemical features, Sm-Nd isotope and tectonic setting, it is concluded that the lamprophyres may occur from depleted mantle wedge which was metasomatosed due to the subduction of Proto-Tethys. |
