以往很少用沉积岩和变质岩的全岩化学成分分析数据对岩石矿物鉴定结果加以验证,本次研究拟对板岩不同岩类样品主量元素进行分析,讨论板岩主要化学成分对板岩分类命名的作用。实验利用X射线荧光光谱仪,通过建立元素测量条件、硅酸盐系列曲线方程参数,利用熔片法,对22件板岩样品进行全岩化学成分分析。统计结果显示:随着板岩中粉砂质含量增加,板岩的挥发系数和颜色指数有逐渐变小的趋势。 In the past, it is seldom used to confirm the identification results of rock minerals by the whole rock chemical composition analysis data of sedimentary rocks and metamorphic rocks. In this study, the main elements of different rock samples of slate are analyzed to discuss the main chemical composition of slate, Named role. Experiments using X-ray fluorescence spectrometer, through the establishment of elemental measurement conditions, the silicate series of curve equation parameters, the use of melting method, the whole rock petrochemical composition analysis of 22 samples. The statistical results show that with the increase of silt content in slate, the volatility coefficient and color index of slate gradually become smaller.
