Summary: Lunar meteorite NWA 13120, a recently discovered breccia, provides important insights into the shock metamorphism of lunar rocks and the evolutionary history of the Moon's surface. Its composition and texture suggest a complex history of impact-related processes that have affected the parent rock.

Summary: The Mg-spinel-bearing rocks are important components of the lunar crust and provide valuable information about the early interaction between the crust and mantle. This study analyzes Mg-spinel and magma melt inclusions in the lunar meteorite Northwest Africa 12279, and reveals the process of rock formation, shedding light on the lunar rock evolution.

Summary: A study of the lunar feldspathic meteorite NWA 11111 revealed its typical lunar origin and diversity of lithic clasts and mineral fragments. The meteorite likely originated from the Feldspathic Highland Terrane on the lunar farside, containing components from the lunar surface to about 10 km deep. The presence of various rock types within NWA 11111 offers new insights into the lunar crust composition and magmatic processes on the farside.

Summary: We provide the first VNIR reflectance spectroscopy characterization of a sample from the lunar feldspathic breccia NWA 13859. Our results show a distinct spectral contribution from orthopyroxene, which is expected to be a minor phase in the sample. We obtained 2D maps of spectral parameters to infer the major mineralogical composition of the sample.

Summary: We studied the composition of the lunar mantle by analyzing low-Ca pyroxene (LCP)-rich and olivine-rich rocks on the lunar surface. Data mining with SELENE (Kaguya) hyperspectral data revealed 531 sites dominated by LCP-rich minerals, mainly located in the Imbrium basin and South Pole-Aitken basin. Stratigraphic analysis showed that LCP-rich rocks are exposed on fresh geological features less affected by space-weathering. The distribution of LCP-rich bodies in impact basins suggests a variation in mantle composition.

Summary: The text discusses the phenomenon of anisotropic absorption in crystals and its application in X-ray absorption spectroscopy. It suggests that visible light absorption theory can be applied to X-ray absorption analysis, and introduces a three-dimensional pedal surface model to describe the relationship between absorption data.

Summary: Oxygen fugacity is an important parameter in primitive arc magmas. This study developed an oxybarometer using the partitioning behavior of Fe3+/Fe2+ between amphibole and glass. The oxybarometer was applied to samples from the Shiveluch volcano, providing information on magmatic oxygen fugacity and shallow magmatic processes.

Summary: This study conducted a petrologic analysis of apatite in various chondrites and determined that chondrites contain either chlorapatite or hydroxylapatite with a maximum of 33 mol% F. It also highlighted the significance of apatite as a mineralogical tool in understanding the origin of volatiles and their associated geological processes in the solar system.
