Abstract：The Kaladawan area is located in the northeast of Altun Mountains, where the Early Paleozoic tectonic settings were complicated, accompanied by intense granitic magmatism. Based on the research of petrology, geochemistry and geochronology of the Early Paleozoic acid-intermediate intrusive rocks in this area, the regional geological events and tectonic settings are discussed. Four of the five plutons in this study are characterized by high-K calc-alkaline. The other presents low-K character. Most of the samples analyzed show the characteristics of I-type granite, with a few as transitional products from I-type to S-type, indicating the active continental margin environment of oceanic-continental crust. Regards Combining the surrounding geological background, this region should be the volcanic island arc when the ancient Altun oceanic crust collided with Tarim massif.
