DOI: 10.1007/s12517-019-4575-x
Abstract: Both adakitic and A-type granitoid have been recently identified in the southern ANS. The Emba-Derho and Koka granitoids yielded the same zircon U–Pb ages of 851 ± 14 Ma and 851 ± 2 Ma, respectively. The Emba-Derho granitoids show… read more here.

DOI: 10.1016/j.gr.2021.04.007
Abstract: Abstract The co-existence of Cretaceous adakitic and A-type granitoids in southern Tibet can offer fundamental constraints on subduction of the Neo-Tethyan oceanic plate and associated crustal growth processes, if their petrogenetic relationships are understood. Here,… read more here.

DOI: 10.1016/j.lithos.2018.12.033
Abstract: Abstract The metaluminous I-type granitoids in the northwestern part of East Junggar include the Kala'an high-K calc-alkaline granodiorite and the Zhalate shoshonitic quartz monzonite, which were emplaced at 331 Ma and 323 Ma, respectively. They represent formations… read more here.

DOI: 10.1016/j.precamres.2019.105585
Abstract: Abstract Neoarchean hybrid granitoids from the Vila Uniao suite are located in the central portion of the Canaa dos Carajas domain, Carajas Province (Amazonian craton, Brazil), and suggest that magma mixing events played an important… read more here.
