The Petrogenesis of the Earliest Early Cretaceous Subvolcanic Granitic Intrusions in the Huoluotai Area, Northern Great Xing’an Range: Implications for the Regional Compression–Extension Tectonic Transition in the Eastern Mongol–Okhotsk Tectonic Domain
Late Mesozoic magmatic rocks are widely exposed in the northern Great Xing’an Range, a key region recording Phanerozoic crustal growth along the eastern Central Asian Orogenic Belt (CAOB). This study integrates petrology, LA–ICP–MS zircon U–Pb geochronology, zircon Hf isotopes, and whole-rock geochemistry for Late Meso...
