Abstract
The ~216-Ma Piaohechuan no. 4 intrusion in northeastern China, situated in the easternmost part of the Central Asian orogenic belt, is composed of hornblende-olivine gabbro overlain by hornblende gabbro. The intrusion is about 630 m long, 40 to 250 m wide, and 50 to 150 m thick. Nickel sulfide mineralization is restricted to the lower part of the intrusion and contains 10,000 metric tons (t) of Ni with average PGE concentrations of 40 ppb Os, 30 ppb Ir, 36 ppb Ru, 26 ppb Rh, 255 ppb Pt and 161 ppb Pd in 100% sulfide.
