如何恢复蚀变超基性岩的原岩,许多研究者进行了不少的工作,并取得了一些成效。但由于所要求的岩石化学全分析项目多,分析时间长,费用高,运用烦琐,不适用于野外工作。我们在前人工作的基础上,根据超基性岩矿物共生组合所决定的岩石化学成分特点,采用简项分析,通过蚀变 How to restore the original rocks of alteration metamorphic rocks, many researchers have done a lot of work and achieved some results. However, it is not suitable for field work due to the large number of rock chemistry full analysis items required, long analysis time, high cost and cumbersome application. Based on the work of our predecessors, based on the characteristics of petrochemical components determined by the symbiotic combination of ultrabasic rocks and minerals,
