| 摘 要： | 化探资料是进行区域地质调查及找矿的重要依据，但在区域化探数据处理过程中，常会遇到一系列问题：如何将不同景观区、不同背景值及不同地质单元的多图幅化探数据进行拼接，不同背景下如何进行异常的筛选及如何综合各成矿元素特征进行选区等。针对这些问题，在利用分区标准化的前提下，利用化探综合异常法，综合考虑主要成矿元素相关性的特征，利用标准化后的综合异常进行异常筛选及区域选区，对区域找矿具有明显的指导作用。

| Abstract: | Geochemical exploration data is an important basis when carried on regional geological survey and prospecting.During process the regional geochemical exploration data,a series of problems occurred:how to splice the multi-sheet geochemical data in different landscape area,background value and geological unit;how to screening abnormality in different contexts;how to select area by general characteristics of the ore-forming elements;and so on.Based on partition standardization,the study uses geochemical exploration composite anomaly method and consider main related characteristic of ore-forming elements.Then,using post-standardized comprehensive abnormal to screen abnormal and to select regional constituencies,it is significant for regional prospecting. |
