Abstract—

The lunar regolith delivered to Earth in the 1970s by the Soviet automatic stations Luna-16, -20, and -24, despite the small amount of material, is of great value for science and requires careful study. However, since soil samples have gone quite a long way from the moment of extraction to direct examination, there is a danger of possible contamination of the samples with foreign material, both man-made and terrestrial natural minerals. The probability of contamination of the finest fraction of regolith, the particle size of which is less than 100 microns, is especially high, since their detection is possible only by electron microscopy. Using the methods of analytical scanning electron microscopy in regolith samples, contaminant phases that contaminated the original preparations were found, and the sources of these artifacts were shown. The examples of contamination of regolith samples given in this paper and the methods for their identification will make it possible in the future to more accurately diagnose the phases of lunar origin.

月球风化层中的污染物

摘要—

苏联自动站Luna-16、-20和-24于 1970 年代将月球风化层运送到地球，尽管材料不多，但具有很高的科学价值，需要仔细研究。然而，由于土壤样本从提取到直接检测已经走了很长一段路，样本存在被异物污染的危险，包括人造和陆地天然矿物。粒径小于 100 微米的风化层最细小部分受到污染的可能性特别高，因为只有通过电子显微镜才能检测到它们。在风化层样品中使用分析扫描电子显微镜方法，发现了污染原始制剂的污染物相，并显示了这些人工制品的来源。
