The modern geologist has a plethora of portable digital tools at their disposal including, GPS, in-field computers providing access to imagery, maps, and on site real time geochemistry provided by portable X-ray fluorescence spectrometry (pXRF). This paper presents an analytical protocol for the examination of Quaternary glaciogenic sediments derived from different bedrock terrains using a portable spectrometer. The protocol outlines best practices for the collection of geochemical data using pXRF from glacoiogenic sediments with generally continental crustal abundance elemental concentrations at a fraction of the cost of traditional laboratory methods. The analytical protocol considers 1) sample preparation, 2) sample analysis, and 3) data cleaning, examination and presentation. The protocol takes into consideration pXRF fundamentals related to, instrument configuration, and an assessment of measurement parameters, including peak overlaps, dwell time, instrument drift, in-situ versus processed samples, variable grain size and moisture content effects, and comparison to traditional laboratory methods. Protocol development occurred over a number of years and analysis of over 4000 geological samples and ~9000 analysis of Certified and Standard Reference Materials.

现代地质学家拥有大量便携式数字工具可供使用，包括 GPS、现场计算机，可提供图像、地图以及便携式 X 射线荧光光谱法 (pXRF) 提供的现场实时地球化学。本文提出了一种使用便携式光谱仪检查来自不同基岩地形的第四纪冰川沉积物的分析方案。该协议概述了使用 pXRF 从具有一般大陆地壳丰度元素浓度的冰川沉积物中收集地球化学数据的最佳做法，而成本仅为传统实验室方法的一小部分。分析协议考虑 1) 样品制备，2) 样品分析，和 3) 数据清理、检查和展示。该协议考虑了与 pXRF 相关的基本原理，仪器配置，以及测量参数的评估，包括峰重叠、停留时间、仪器漂移、原位与处理样品、可变粒度和水分含量的影响，以及与传统实验室方法的比较。协议开发经历了多年，对 4000 多个地质样品进行了分析，并对认证和标准参考材料进行了约 9000 次分析。
