Granites occurred in the Gaoligong tectonic belt were controlled by Nujiang deep fault. The granites emplaced in SN direction as long and narrow lens. The SHRIMP age of zircon from granites is 124~118 Ma. As well, the 40Ar/39Ar dating of biotite from granitic mylonites is 18~10 Ma, same with the deformed age of mylonitic granites from Chayu. This indicates that these plutonic units intruded in order. All these above proposed that the granites in the tectonic belt from Bomi-Chayu to Gaoligong crystallized in 124~118 Ma. The strike-slip peak time of Nujiang deep fault is 18~10 Ma. In this period, the slide in large scale took place in Atyn Tagh fault, Ailaoshan-Honghe fault.
