从一个项目，以寻找和描述原始（即成分内源性）nonmare岩石的最新结果的报告。十六个非母马样本进行了岩石学和成分特征分析，其中包括许多关键微量元素（亲铁物质、不相容物质）。目前的知识nonmare月球岩石进行了调查，重点放在地球化学和经度之间的相关性。西方ANT（即nonKREEPy，nonmare）岩石和更深入研究的东部ANT岩石之间的几个系统的差异。值得注意的是，西部ANT岩石，无论是原始或非原始，往往有较高的Eu/Sm比他们的东部同行。然而，原始的西部ANT岩石往往比原始的东部ANT岩石具有更低的Sc/Sm和Ti/Sm。
The most recent results from a project to find and describe pristine (that is, compositionally endogenous) nonmare rocks are reported. Sixteen nonmare samples are characterized petrographically and by composition, among them numerous key trace elements (siderophiles, incompatibles). Current knowledge about nonmare lunar rocks is surveyed, with emphasis placed on correlations between geochemistry and longitude. Several systematic differences between western ANT (that is, nonKREEPy, nonmare) rocks and the much more thoroughly studied eastern ANT rocks are noted. It is noted that western ANT rocks, whether pristine or nonpristine, tend to have higher Eu/Sm than their eastern counterparts. Pristine western ANT rocks, however, tend to have lower Sc/Sm and Ti/Sm than pristine eastern ANT rocks.
