摘要

摘要: 便携式X射线荧光光谱仪（pXRF）能够快速无损地原位分析常见岩石的主微量元素组成。为提高pXRF在地质样品分析中的准确性，本文选取了39件地质参考物质，包括火成岩、碳酸盐岩、碎屑沉积岩和沉积物等，使用Olympus Vanta pXRF对其粉末压片进行测定分析，并依据实测元素含量的多次测定平均值与参考物质推荐值之间的相关关系建立校准曲线。本研究确定了TiO₂、Sr、Zr、Y、Nb、Cu本身良好的精密度和准确度；发现了SiO₂和CaO含量在碳酸盐岩与火成岩、碎屑沉积岩-水系沉积物-土壤之间受基体效应影响明显，需对其分别建立不同的校准方程进行校准；此外，通过回归分析，本研究显著提高了Al₂O₃、Fe₂O₃^T、MnO、K₂O、Rb、Zr、Pb、Zn、Cr、Ni、Nb元素的测量准确性。而后选取燕山科学钻探的凌源钻孔（YSDP-4）前150米岩心为研究对象，将其pXRF校正前后的数据与熔片法进行对比，结果证实校准后的数据与全岩粉末数据更加贴合。结果证实通过该方法可以有效提高数据准确度，并扩展了pXRF仪器在岩心快速扫描分析中的广泛应用潜力。
