Early cretaceous lower crustal reworking in NE China: insights from geochronology and geochemistry of felsic igneous rocks from the Great Xing’an range

This paper presents new zircon LA-ICP-MS U–Pb ages and whole-rock geochemical data for two granitic plutons and rhyolites of the Baiyingaolao Formation in the western Xing’an range (NE China). The two syenogranite granitic plutons yield identical zircon U–Pb age of 142 ± 1 Ma, and the Baiyingaolao rhyolites yield zircon U–Pb age of 138 ± 2 Ma. The granites contain some hornblendes, and show low Zr and Zr + Nb + Ce + Y contents, and low A/CNK...
