以矿区地球化学元素数据为例,采用数理统计方法和分形方法对数据进行了处理,并按不同方法确定的异常下限分别圈定地球化学异常图,探讨了地球化学异常与矿化地段之间的关系,指出分形方法圈定的地球化学异常与矿化体关系更密切,其内带往往就是矿化体的发育地段。 Taking the geochemical element data of mining area as an example, the data were processed by mathematical statistics and fractal methods, and the geochemical anomaly maps were delineated by different methods to determine the lower limit of anomaly. The relationship between geochemical anomalies and mineralized areas was discussed , Pointing out that the geochemical anomaly delineated by the fractal method is more closely related to the mineralized body, and the inner zone is often the developmental area of ​​the mineralized body.
