Nature of Ore Fluid at the Sopokomil Zn-Pb Deposit, North Sumatra, Indonesia: Implications for Metal Transport and Sulfide Deposition

Autor: Tomy Alvin Rivai, Syafrizal, Kotaro Yonezu, Kenzo Sanematsu, Koichiro Watanabe

Publikováno v: Geosciences, Vol 11, Iss 7, p 298 (2021)

Little is known about the nature of ore fluid at the Sopokomil shale-hosted massive sulfide Zn-Pb deposit (North Sumatra, Indonesia). We therefore investigated its ore-fluid salinities, temperatures, densities, redox state, and pH using fluid inclusi
