... dikes in the Carboniferous (~320–310 Ma); and the emplacement of the Permian Khanbogd Granite alkaline batholith (~290 Ma). Both Carboniferous and Permian alteration events variably overprint the earlier porphyry alteration halo. Overdispersion in the U-Pb data from some samples, due to Pb and/or U...

... and Neoproterozoic dolomitic limestones, associated with which is the c. 100 km 2 Ailanghe granite batholith ( Zhong et al. 2011 ). According to the petrographic description of the granite by these authors, it is a biotite granite and contains neither sodic pyroxene nor amphibole. However, dating reported by B...
