不同化探数据处理方法在找矿中的应用--以四川会理县银星铁铜矿为例

摘要

The traditional geochemical exploration data processing methods often ignore the differences in geochemical background between different geological units. This paper applies the traditional data processing method, contrast anomaly method and fractal method to data processing of the 1:25000 soil survey in Yinxing, Huili Country, Sichuan Province. The results indicate that the contrast anomaly method is simple, but ineffective in the high background area, while the fractal method is complicated, but it can strengthen geochemical anomalies in the districts of different backgrounds.%在四川会理县银星地区1：2.5万化探工作中，分别采用传统数据处理方法、衬度异常法、分形法进行数据处理，分析结果认为：衬度异常法计算过程简单，但对高背景区域异常的分解效果不明显；分形法计算过程复杂，却能强化不同背景区的地球化学异常。具体工作中通过不同数据处理方法的组合，择优进行推断解译，具有强化弱异常信息，提高找矿效率的重要功效。
