将相态分析的方法应用于化探异常样品的分析中,可对异常样品进行快速筛选和评价。根据黑龙江省的高寒高有机质的区域景观条件,将Mo元素分为水提取相、弱有机质结合相、氧化物相、硫化物相和铁结合相五个相态。分相后采用ICP-MS进行测定。分析结果表明,Mo以铁结合相为主,弱有机质结合相的含量也很高。因此,对于高寒高有机质这一特殊景观此相的分析是必要的。
The method of phase analysis is applied to the analysis of abnormal geochemical samples, which can be used to rapidly screen and evaluate abnormal samples. According to the regional landscape of alpine and organic matter in Heilongjiang Province, the Mo element is divided into five phases: water phase, weak organic matter phase, oxide phase, sulfide phase and iron bond phase. Phase separation was followed by ICP-MS. The results show that the main phase of Mo is iron-bound phase, and the content of weak-organic phase is also high. Therefore, it is necessary to analyze this phase of the special landscape of alpine and high organic matter.
