“…The collision formed a series of NS trending folds (e.g., Hetaoping anticline), and many NS and NE trending faults in Baoshan block. The deposit types in the Baoshan block include magmatic Cu-Ni deposits (e.g., Daxueshan; [24]), Skarn Pb-Zn polymetallic deposits (e.g., Hetaoping, Jinchanghe, Luziyuan; [3,25,26]), epithermal Pb-Zn deposits (e.g., Xiyi, Dongshan; [27]) and magmatic-hydrothermal Sn-W deposit (e.g., Shiganghe, Tiechang; [22]).…”

The Jinchanghe Pb-Zn polymetallic deposit is a representative distal skarn deposit in the Baoshan block. Due to limited research on the sources of ore-forming metals and trace elemental geochemistry of sulfides, the sources and mineralization environments of the Jinchanghe skarn Pb-Zn polymetallic deposit are still controversial. In this study, copper and sulfur isotopes and trace elements of sulfides from the Jinchanghe Pb-Zn polymetallic deposit were analyzed to reveal the sources of ore-forming materials and the ore-forming environments. The trace elemental analysis results show abundant Co, Ni, Mn and Se elements, and less As, Tl and Sb elements dominantly enter pyrite by isomorphic substitution, except for some Zn and Cu that occur as sulfide inclusions in Py1. Abundant Fe and Mn elements could substitute Zn to enter the sphalerite crystal lattice by the isomorphic substitution mechanism of (Fe2+ + Mn2+) ↔ 2Zn2+, and less Ag and Sb elements could enter the sphalerite by the isomorphic substitution mechanism of (Ag+ + Sb3+) ↔ 2Zn2+. The Cu-S isotopic and trace elemental compositions jointly suggest that the Jinchanghe distal skarn Pb-Zn polymetallic deposit formed from magmatic hydrothermal fluids with a sedimentary host-rock contribution, under mesothermal conditions (260 °C on sphalerite).

“…One kind of deposit enriched with Pb-Znbearing minerals and found in almost all metallogenic belts in Indonesia is a skarn deposit (Dana et al, 2019;van Leeuwen, 2018). The existence of the skarn deposit itself is always associated with carbonate-rich rocks that undergo a metamorphism and metasomatism process due to contact with intrusive rock such as those in Erstberg in Papua (Bensaman et al, 2015), Ruwai in Kalimantan (Idrus et al, 2011), and Tuboh in Sumatra (Xu et al, 2021). The Kujang skarn prospect at Sukabumi Regency is one of the newest economically significant skarn deposits in the Sunda-Banda Arc.…”

The Kujang Pb-Zn skarn deposit is known to be the newest skarn deposit found in the Sunda-Banda magmatic arc. The skarn orebodies are mostly hosted by limestone which might be the part of the Jampang Formation where dacite porphyry is interpreted to be the ore causative intrusion. Orebodies are mostly found at the contact between marbleized limestone and volcanic rocks and are controlled by NW-SE-trending strike-slip faults. Previous research on the mineralogy and ore characteristics of the Kujang Prospect remains limited on the preliminary studies. Using fieldwork data, petrography, ore microscopy, and assay data from core samples, this study is aimed to characterize the mineralogy of both alteration and ore of the deposit. The alteration of the Kujang Prospect skarn can be divided into 2 phases of alteration i.e. prograde and retrograde. The prograde alteration is characterized by the occurrence of clinopyroxene, wollastonite, and vesuvianite. Garnet is present in very rare amounts. the retrograde alteration is typified by epidote, chlorite, calcite and actinolite. Metalliferous minerals are represented by sphalerite, galena, pyrrhotite, chalcopyrite and pyrite. All ore minerals are formed at the early retrograde stage. the deposit’s average grade is 2.06% Pb, 6.45% Zn and 1.81% Cu.
