岩矿鉴定工作,对沉积岩的粒度组分及矿物组分的计量,是项不可缺少的极为重要的工作。它的意义不仅在于能否对样品组分的含量进行客观地反映,更重要的是这些计量资料影响着岩石的分类与命名,影响着地质应用和推论。 在石油地质和一般地质工作中,岩矿鉴定使用的方法多为“目估法”。“目估法”有它自己的优点——比较快速,为人们广泛重视和应用;不可否认,它存在一个致命的缺点,就是主观性较强,以至在工作中难以克服,严重地影响了鉴定质量,针对这个问
Identification of rock and mine, sediment rock particle size and mineral composition measurement, is an indispensable and extremely important work. Its significance lies not only in whether the content of the sample components can be objectively reflected, but more importantly, these measurement data affect the classification and naming of rocks and affect geological applications and inferences. In petroleum geology and general geological work, the methods used in rock and mine identification are mostly “eye estimation methods.” It is undeniable that it has a fatal flaw, that is, its subjectivity is so strong that it can hardly be overcome at work and seriously affects the identification Quality, for this question
