The Tekesi Daban batholith can be divided into two intrusive series, i.e., Early Carboniferous Kulesayi series and Early Permian Qinaersayi series. The porphyry assemblage of the Kulesayi series is a calc-alkaline series formed in an island arc environment. SiO2 is 57.06％～70.74％, the Rittmann index (σ) is lower than 3.26, and（Na2O+K2O）/Al2O3 is lower than 0.9. It is enriched in Al2O3, Na2O, Sr and LREE, and poor in MgO, Y, Yb and HREE; Na2O / K2O is higher than 1, Sr/Y is 57. 67, δEu is 1.22，indicating O-type adakite. The Kulesayi series is enriched in Cu, Mo and W, and even contains Mo ore bodies. In the Qinaersayi series, SiO2 is 76.75％～77.83％, σ is higher than 3.3, （Na2O+K2O）/Al2O3 is higher than 0.9， andδEu is 0.07; this series is poor in Ba, Sr, Ni, Sc but enriched in Rb, Y, Zr, Th, Ta, with Sr/Y being 3.24. The protolith was partly derived from melting of argillaceous rocks of the earth crust, belonging to the alkaline series formed in an intrap late rift environment. Geochemical characteristics provide not only powerful evidence for the disintegration of the Tekesi Daban batholith but also abundant information for the improvement of native metallogenic regularity. In addition, these characteristics enrich types of tectonite assemblage, guide ore-prospecting work and contribute to researches on tectonic evolution.
