Chemical analysis showed that the fresh basalts and corestones slightly changed in composition except that variations in Fe(superscript 2+) to Fe(superscript 3+) are most noticeable. In the course of corestones changing to saprolite elements of Si, Ca, Na and Mg, the ratio of SiO2/Al2O3 decreased gradually, while the elements of Fe, Al and the values of LOI and CIA significantly increased.

化学全分析结果表明新鲜玄武岩与核心石在除Fe外，其它组分无明显的改变；核心石在转变为腐岩过程中Si、Ca、Na、Mg等元素逐渐流失，Fe、Al等逐渐富集，同时烧失量LOI和化学蚀变指数CIA显著增加，硅铝比逐渐减少。

There are strong to weak schistosity from rim to centre in all the dikes. The chemical compositions of the dikes are similar to that of the basalts.

无论哪种产状的脉体都发育片理化现象，且从脉体的边缘向中心减弱。

It shows that the magma forming the syenite in the Luzong basin was derived from a deep source, most likely resulting from the partial melting of an alkali basalts along the deep fault, and obviously contaminated by continental crust material.

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。
