The same set of ductile-rheologic shear deformational augen granite samples in the Yunkai uplifted area are measured by whole-rock Sm-Nd, Rb-Sr isotopic dating system method, obtaining respectively 1414±68Ma for Sm-Nd isochron age and 490±36Ma for Rb-Sr isochron age. These ages are respectively interpreted as the time of the granitic rock formation and the time of the tectono-thermal event of ductile-rheologic shear partial melting in Caledonian, indicating that the orogeny not only took place in Caledonian, but also the more important tectono-magmatic orogeny in the late Mesoproterozic Era and can be compared with the time of global Grenville orogeny.
