摘要
用离子色谱法测定了黔东南某些石英脉型金矿床的石英流体包裹体浸取液中的短链羧酸和无机组分，发现其中含有甲酸盐、乙酸盐和少量草酸盐，且Ｃ（ 甲酸盐） ＞ Ｃ（ 乙酸盐） 。所研究的石英中包裹体的均一温度高于２００ ℃。一元羧酸盐可能是中高温成矿流体中的重要组分。
The short\|chain carboxylates and inorganic composition of leachates from the fluid inclusions in some quartz vein\|type gold deposits in the southeastern Guizhou Province were determined by ion\|chromatogrphy. There are some formate, acetate and oxalate in leachates in small amounts, and the content of formate is greater than that of acetate. Homogenization temperatures of fluids inclusions in quartz studied are above 200℃. Monofunctional carboxylates probably are the important components of meso\|high temperature ore\|forming fluids.
