Geochemistry and geochronology of the Dongshanwan porphyry Mo–W deposit, Northeast China: Implications for the Late Jurassic tectonic setting

The Dongshanwan porphyry Mo–W deposit is located in the southern segment of the Da Hinggan Mountains of the eastern segment of the Central Asia Orogenic Belt. More than 95% of the mineralization occurs within the Dongshanwan granite porphyry, with a small part being hosted within quartz veins that crosscut the Late Permian strata. Zircon U–Pb age measurements indicate that the Dongshanwan granite porphyry has a 206Pb/238U age of 151.4 ± 0.8 Ma....
