| 摘 要： | 区域地球化学场是实现地质和地球化学问题互相转化的重要界面之一，它具有不同层次上的结构性。系统研究区域地球化学场的结构特征和规律，尤其是成矿体系地球化学场的结构特征，对揭示区域地质背景、成矿环境和控矿因素具有重要作用；其次，它把“孤立异常”有机的联系起来，有助于提高对局部异常评价的合理性和可靠性。研究区域地球化学场可用区域分散流普查资料来进行。

| Abstract: | As one important way converting geology and geochemistry into each other, the regional geochemical fields represent nature of structures at different level. Systematic studies on structure and regulation of regional geochemical fields, especially on that of metallogenic system, play an important role in revealing regional geological background, metallogenic environments and ore controls. Enabling the "isolated anomalies" connected, it is useful for improving the resonablness and trustiness of local anomalies assessment. Regional stream sediment data can be used in studies of regional geochemical fields. |
