摘要
地球化学场可定义为地球化学变量在各种尺度的区域上的分布．地球化学场是各种地质地球化学作用的对象和空间载体．成矿作用及其他各类地球化学过程都可理解为地球化学场空间结构随时间的演化，即地球化学场的时－空结构．本文把地球化学场时－空结构分析厘定为一维时－空序列的分析、二维场空间结构分析、三维场空间结构分析和数值矿床模型、时－空结构的动力学分析等４部分内容。
Geochemical fields, defined as spatial distribution of geochemical variables in regions of various sizes, are objects and spatial carriers of diverse geochemical and geological processes. Ore_forming and other geochemical processes can be viewed as temporal evolution of spatial structure, or as temporal_spatial structure of geochemical fields. Much emphasis in this paper is laid on temporal_spatial structure analyses of geochemical fields which have been clustered by the authors into four categories: one_dimensional analysis of temporal and spatial sequences, two_dimensional analysis of field spatial structure, three_dimensional analysis of field spatial structure, and digital ore_deposit modeling and dynamic analysis of temporal_spatial structure. The methodology for each category is discussed in detail.
