“…Plot of δ 18 O and δ 13 C values for veins of calcite and dolomite from stages III to IV of the Huai Kham on deposit. The δ 18 O and δ 13 C values for veins of calcite from the Chatree epithermal deposit, veins of dolomite‐ankerite carbonate in SW Highland in Scotland (Anderson et al ., 2004) and Triassic limestone (Tangwattananukul, 2015) in Thailand are also plotted for comparison…”

“…Many mineral deposits are distributed in Thailand along the Loei‐Phetchabun and Sukhothai Fold Belt including the Puthep copper‐gold skarn deposit, Phu Thap Fah gold skarn deposit, Chatree epithermal gold deposit, Khao Pranom Pha gold skarn deposit, Ban Bothong gold skarn deposit, Huai Kham On gold deposit, and Huai Yuak gold deposit (Shawee, 1984; Sitthithaworn et al ., 1993; Zaw et al ., 2007; Khositanont et al ., 2007a; Kamvong and Zaw, 2009; Kamvong et al ., 2014; Tangwattananukul et al ., 2014; Zaw et al ., 2014; Tangwattananukul, 2015; Tangwattananukul and Ishiyama, 2018) (Figure 1a). Previous studies suggested that the gold deposits in the Loei‐Phetchabun Fold Belt are spatially and temporally associated with subvolcanic intrusions (Sillitoe and Bonham Jr., 1984; Salam et al ., 2008; Tangwattananukul et al ., 2014; Tangwattananukul and Ishiyama, 2018).…”

The Huai Kham On gold deposit is located in the central part of the Sukhothai Fold Belt, northern Thailand. The Sukhothai Fold Belt represents an accretionary complex formed by subduction and collision between the Indochina and Sibumasu Terranes. There are many small gold deposits in the Sukhothai Fold Belt; however, the styles and formation environments of those gold deposits are not clear. The geology of the Huai Kham On deposit consists of volcanic and volcanosedimentary rocks, limestone, and low‐grade metamorphic rocks of Carboniferous to Triassic age. Gold‐bearing quartz veins are hosted by volcanic and volcanosedimentary rocks. The quartz veins can be divided into four stages. The mineral assemblage of the gold‐bearing quartz veins of Stages I and II comprises quartz, calcite, illite, pyrite, native gold, galena, chalcopyrite, and sphalerite. Quartz veins of Stage III consist of microcrystalline quartz, dolomite, calcite, pyrite, native gold, and chalcopyrite. Veins of Stage IV consist of calcite, dolomite, chlorite, and quartz. Fluid inclusions in quartz veins are classified into liquid‐rich two‐phase (Types IA and IB), carbonic‐aqueous (Type II), and carbonic (Type III) fluid inclusions. The homogenization temperatures of Types IA and II fluid inclusions that are related to the gold‐bearing quartz veins from Stages I to III ranged from 240° to 280°C. The δ18O values of quartz veins of Stages I to III range from +12.9 to +13.4‰, suggesting the presence of a homogeneous hydrothermal solution without temperature variation such as a decrease of temperature during the formation of gold‐bearing quartz veins from Stages I to III in the Huai Kham On gold deposit. Based on the calculated formation temperature of 280°C, the δ18O values of the hydrothermal solution that formed the gold‐bearing quartz veins range from +3.2 to +3.7‰, which falls into the range of metamorphic waters. The gold‐bearing quartz veins of the Huai Kham On deposit are interpreted to be the products of metamorphic water.
