Abstract

En 中文

• Iron Formation in Fushun Area consists mainly of ferrosilicate minerals with accessory pyrite and magnetite. • Depositional and metamorphic ages are constrained to 2533.0 ± 6.8 Ma and 2485.7 ± 7.8 Ma, respectively. • Material sources were dominated by submarine hydrothermal activity under anoxic, weakly acidic conditions.
