1. Eiji Izawa, Tetuya Nakanishi, Japanese silver mining from 674 to early seventeenth centuries and lead isotopic ratios of silver ores, 日本鉄鋼協会, 2019.03.
2. Seang Sirisokha, TETSUYA NAKANISHI,,KOTARO YONEZU, Akira Imai, Thomas Tindell and Koichiro Watanabe, Hydrothermal alteration, mineralization and fluid inclusion microthermometry of the Halo prospect porphyry copper-molybdenum, Southeast of Cambodia, International Symposium on Earth Science and Technology 2018, 2018.11, The Halo prospect porphyry copper-molybdenum is located in Southeastern part of Cambodia. This prospect is hosted by porphyritic diorite, porphyritic granodiorite, feldspar porphyry, andesite dykes, and rhyolite dykes. The hydrothermal alteration and mineralization can be divided into four stages, stage 1; quartz+magnetite± molybdenite±chalcopyrite ±pyrite vein, stage2; quartz+molybdenite±chalcopyrite±pyrite vein, stage 3; quartz pyrite ±chalcopyrite±sphalerite vein, stage 4; anhydrite±calcite±pyrite vein. Five main alteration assemblages were identified: potassic-sericitic, phyllic, propylitic, intermediate argillic, and silicic alteration. Hydrothermal quartz mainly contains four types of fluid inclusions: type I (liquid+vapor), typeII (liquid+vapor+anhydrite), typeIII (liquid+vapor+opaque) and type IV (liquid+vapor+halite). The homogenization temperatures (Th) (from vapor+liquid to liquid) of type I, type III, and type IV fluid inclusions in quartz veins associated with the potassic-sericitic alteration range from 185 to 309oC, 329 to 400oC and 229 to 460oC with salinity ranging from 2 to 8 wt.% 14 to 17 wt.% 35 to 58 wt.% NaCl equiv., respectively. On the other hand, the Th (from vapor+liquid to liquid) of type I, type II, type III, and type IV fluid inclusions in quartz in the silicic alteration range from 201 to 290oC, 285 oC, 210 to 286oC and 290 to 381oC with salinity ranging from 0.5 to 11 wt. %, 16.wt. %, 8 to 21 wt. %, and 40 to 52 wt. % NaCl equiv., respectively..
