It is proposed that the Jiabula Formations: Chuangde Formation and Zongzhuo Formation constitute the Cretaceous in this area, in which their sequences, ages and thicknesses are distinctively different from the previous ones. The Jiabula Formation, aged from Berriasian to Santonian, is composed of black shale with intercalated turbiditic sandstone, lenticular limestone and pyrite展开更多

Isotopic age studies of the zircons from both the metamorphic rocks and their anatectic derivatives by the single crystal U-Pb method have been carried out by the authors. The upper intercept age of the U-Pb concordia has been interpreted as the age of metamorphism or anatexis of the samples concerned. The results of the isotopic determination of zircons from the samples of three different rock types collected near Xiaojue and in the area further east(Fig. 1) give the age of regional metamor-展开更多
