鉴于基性-超基性岩及其有关矿产的研究工作不断深入,积累的岩石化学资料日益增多,对其加工整理确实是一项复杂而繁重的任务。因此,必须有一个从理论到实践上都比较简便的岩石化学计算方法,以解决当前存在的问题。近几年来,我们在运用国内一些主要方法的基础上,吸取了前人的优点,利用几个比值,反映超基性岩基性程度和镁铁组分的变化关系,并通过简便的计算即可确定橄榄石和辉石的含量,进行岩石定
In view of the deepening of research on basic-ultrabasic rocks and their related minerals, the accumulation of petrochemical data is increasing day by day, and the processing and finishing thereof is really a complicated and heavy task. Therefore, there must be a petrophysical calculation method that is relatively simple in theory and practice to solve the current problems. In recent years, based on some major domestic methods, we draw on the advantages of our predecessors and make use of several ratios to reflect the relationship between the basicity of ultrabasic rocks and the composition of mafic materials. Through simple calculations The content of olivine and pyroxene can be determined for rock setting
