Southward extension of the Bangonghu–Nujiang Suture: Evidence from Early Cretaceous intermediate and felsic magmatism in the Gaoligong Orogen, China

It remains debated as to whether the Gaoligong Orogen between the Tengchong and Baoshan blocks in Yunnan, China, is the southward extension of the Tibetan Bangonghu–Nujiang Suture (BNS). Here we present new geochronological and petrochemical data for Early Cretaceous magmatic rocks of the Gaoligong Orogen. The LA–ICP–MS U–Pb dating of zircons from diorites, granodiorites, and granites yielded weighted mean 206Pb/238U ages of 120–118, 128–122,...
