The Early Devonian intrusive rocks in central Kunlun fault and its adjacence area in east Kunlun is effected by central Kunlun fault activity, deformed strong, showed irregularly lens shaped in horizontal plane, distributed approximately west—east direction along the central Kunlun fault. In lithogeochemistry, the intrusive rocks have characteristics of subalkaline, highK—lowK calcalkaline,, metaluminous—peraluminous. In R1—R2 diagrams they plot in the areas of black granite, tonalite, granodiorte, and monzogranite . In normalized traces element patterns, they are enriched in Rb,Th,Ba, deeply depleted in HFSE（Nb,Ta）. In chondritenormalized REE patterns, they are enriched in LREE，depleted in HREE ，the curves behave right inclined, and have volcanoarc granitic characters. Based on regional geological data and tectonic setting diagrams of granites, the Early Devonian intrusive rocks studied in this paper are postcollisionorogenic granites, the material resources originated from interaction of crust—mantle. It is concluded that the collisionorogenic movement had taken place in east Kunlun during late Caledonian orogeny.
