英文摘要This paper reports the isotopic age of qi'eshan group, the wallrock of tuwu-yandong porphyry copper deposits in eastern tianshan mountains. the analyses by shrimp shows that the zircon crystals separated from the andesite within qi'eshan group have the concordant u-pb age of 336.5 +/- 6.6 ma, and the sm-nd isochronic age of the basalt and its constituent minerals, diopside and plagioclase, collected from the same group is 334 36 ma. these results conformably demonstrate that qi'eshan group was formed in early carboniferous epoch. the basalts of qi'eshan group are of island are tholeiite series, and are characterized by moderate enrichment of the lree relative to the hree. they all show significant enrichment of large ion lithophile elements and relative depletion in high strength field elements relative to n-morb, indicating that qi'eshan group was formed at a subduction zone setting, in accordance with the tectonic discrimination diagram. the geochronological determination of qi'eslian group provides important constraints for the petrogenetic and metallogenic age of the deposits and its tectonic setting, which were much controversial issues before.
