摘要
地球化学调查的作用随比列尺的不同而变化.对区域地球化学调查所获异常的解释,必须考虑调查中不同比例尺在性质和目的上的差异,不应对区化资料作"超负荷解释".寻找特定矿床类型或研究特殊元素组合时,应采用中或大比例尺追踪调查.文中列举了4个干旱环境的案例,以说明区域调查和详查之间异常模式有明显不同.
The purpose of geochemical surveys changes with scale. The interpretation of regional geochemical surveys must take into account scale-dependent differences in the nature and objectives of this type of survey. Overinterpretation of regional data should be resisted, as should recommendations to restrict intermediate o? detailed follow-up surveys in the search for specific deposit types or in a toc-1 mited suite of elements. Four examples from arid environments illustrate the dramatic change in patterns of anomalies between regional and more detailed surveys.
