EARLY CRETACEOUS EXTENSION IN UPPER-MIDDLE CRUST OF NE ASIA: EVIDENCES FROM WIDESPREAD SYN-THINNING GRANITIC DOMES

https://doi.org/10.5800/GT-2017-8-3-0264

Аннотация

Numerous Early Cretaceous syn-thinning granitic domes are widespread in Mongolia and China-Mongolia border area. We observed relationships between deformation and magmatic activity that occurred in Baoder, Naran, Hanwula, Erdene, Altanshiree, Nartyn dome[Daoudene et al., 2012; Cheng et al., 2014; Guo et al., 2015], which developed in eastern Mongolia and China-Mongolia border area during Early Cretaceous crust-scale NW–SE extension.
