1. In addition, Syafrizal et al. (2005) described the vertical metal zoning of the precious metal (gold-silver)-rich zone overlying on the base metal (copper-lead-zinc)-rich zone at the Ciurug vein, Pongkor deposit. Mil�si et al. (1999) described the wide distribution of supergene mineralization at the Pongkor deposit, while the Ciurug vein has limited weathered zone than in other veins. Therefore, metal zoning in the Ciurug vein was presumably formed by hypogene mineralization. Detailed fluid inclusion microthermometry for the Ciurug vein was conducted by;( Indonesia;Indonesia Boiling was indicated by fluid inclusion microthermometry and the presence of lattice-bladed calcite in the vein at the Pongkor deposit,1994
