When selecting a method for determining modal mineralogy and elemental composition of geological samples (e.g., meteorites), a number of factors should be considered, includingthe number of objects or the area to be analyzed; the scale of expected chemical variation; instrument time restrictions; and post-processing time. This study presents a method that minimizes acquisition time while maintaining the ability to distinguish minerals based on combinations of intensities of electron probe micro-analyzer-generated X-ray element maps. While some other methods yield similar outcomes, this method's post-processing utilizes standard parameterized, X-ray intensity “map math” in an algorithm that is adaptable and requires minimal supervision once implemented. This study's minimized supervision in the post-processing of X-ray intensity maps decreases analysis time and its adaptability increases the number of potential applications. The method also facilitates calibration of the exact locations of analysis using laser ablation methods. While the method described here has advantages, the choice of method always depends on the question being asked.

减少对陨石样品定量图像分析的监督

在选择确定地质样品（例如陨石）的模态矿物学和元素组成的方法时，应考虑许多因素，包括要分析的物体数量或区域；预期化学变异的规模；仪器时间限制；和后处理时间。本研究提出了一种方法，该方法可最大限度地缩短采集时间，同时保持基于电子探针微分析仪生成的 X 射线元素图的强度组合来区分矿物的能力。虽然其他一些方法会产生类似的结果，但该方法的后处理在算法中使用了标准参数化的 X 射线强度“映射数学”，该算法具有适应性，并且一旦实施就需要最少的监督。这项研究' 在 X 射线强度图的后处理过程中最小化的监督减少了分析时间，其适应性增加了潜在应用的数量。该方法还有助于使用激光烧蚀方法校准分析的确切位置。虽然此处描述的方法具有优势，但方法的选择始终取决于所提出的问题。
