摘　　要：本文将化探样品中金分为：水提取态、黏土吸附态、有机结合态、铁锰氧化态、自然金态、碳酸盐态，硫化物态和硅酸盐态八个相态，详细介绍了各相态的浸取流程，采用ICP—MS进行测定。分析结果表明金在各相态含量差异较大，能明显区分各相的存在，将其应用到黑龙江省某地区的化探异常样品分析中，结果可提供比较准确的矿致异常信息。Gold in Geochemical Exploration Samples divided into water extractable, clay adsorbed, organic state, iron and manganese oxidation state, state of native gold, carbonate phase, the sulfide state and silicate state eight phase states, designed phase separation process and measured using ICP-MS. The analysis results showed that the gold content in each phase state difference can clearly distinguish the presence of each phase. A phase analysis method of Gold is applied to the sample analysis of geochemical anomalies in a region of Heflongjiang Province. Results can provide more accurate mine exception information.
