月球背面的薛定谔盆地直径为1320公里，是地月系统中保存最完好的峰环盆地。在这里，我们提出了光谱和photogeologic分析的数据从月球矿物学制图仪的月球飞船-1和月球勘测轨道飞行器相机（LROC）的LRO航天器，这表明峰环是由斜长岩，正长岩和troctolitic岩性，并置的几个横切断层在峰环的形成。Hydrocode模拟表明，这些岩石是从30公里深处隆起的，代表了月球背面的地壳。通过地质和遥感观测与数值模拟相结合，我们表明，位移结构不稳定模型是最好的峰环，包括在地球上的K-T希克苏鲁布撞击坑。这些结果可能有助于指导多机构国际空间探索协调小组正在研究的月球样品返回任务中的样品选择。月球上的撞击盆地被认为是恢复月球内部信息的最佳着陆点。为了告知未来的月球任务，Kring等人将联合收割机遥感和数值模拟相结合，以生成薛定谔撞击盆地峰环的地质图。
The Schrödinger basin on the lunar farside is ∼320 km in diameter and the best-preserved peak-ring basin of its size in the Earth–Moon system. Here we present spectral and photogeologic analyses of data from the Moon Mineralogy Mapper instrument on the Chandrayaan-1 spacecraft and the Lunar Reconnaissance Orbiter Camera (LROC) on the LRO spacecraft, which indicates the peak ring is composed of anorthositic, noritic and troctolitic lithologies that were juxtaposed by several cross-cutting faults during peak-ring formation. Hydrocode simulations indicate the lithologies were uplifted from depths up to 30 km, representing the crust of the lunar farside. Through combining geological and remote-sensing observations with numerical modelling, we show that a Displaced Structural Uplift model is best for peak rings, including that in the K–T Chicxulub impact crater on Earth. These results may help guide sample selection in lunar sample return missions that are being studied for the multi-agency International Space Exploration Coordination Group. Impact basins on the Moon are considered as the best landing sites for the recovery of information about the lunar interior. To inform future lunar missions, Kring et al. combine remote sensing and numerical modelling to generate a geological map of the Schrodinger Impact Basin peak ring.
