Fe isotope behaviours during sulfide-dominated skarn-type mineralisation

null null Fe isotope compositions of mineral separates and bulk samples from Dongguashan and Fenghuangshan skarn type Cu–Fe deposits in Tongling District, Middle–Lower Yangtze Valley Cu–Fe–Au–Mo polymetallic belt have been investigated. Differences in δ 57 Fe values exist in co-precipitated bornite–chalcopyrite and pyrite–chalcopyrite mineral pairs. The bornite is enriched in light iron isotopes relative to coexisting chalcopyrite, whereas...
