The Cu data appears to divide into a normal distribution for values below the first population upper limit 20 ppm for the fractal plot and one or more lognormal distributions above 20 ppm thresholds, which can identifies both the regions of Tertian basalts and main trend of Cu mineralization.

铜元素数据划分二个部分，一部分是元素含量少于20ppm的正态分布数据，另一部分是元素含量大于20ppm的多个对数正态分布数据，能识别第三纪玄武岩区域和铜的主要矿化区。这一结论与使用传统的概率图模型方法得到的结论一致。
