Lunar impact glasses can provide important information on the bulk compositions of their sources and history Moon. Here, we report chemical composition fifty-four clean glass spherules containing neither relict clasts nor crystals from Chang'e-5 (CE5) regolith. They be subdivided into three compositional groups: (1) mid-Ti basaltic (TiO2 = 4.1 ∼ 6.5 wt%), (2) low-Ti 1.3 3.9 (3) high-Al (Al2O3 > 15 wt%). Fifty-one (∼94 %) are basaltic, which form a loose cluster for most major trace elements....

Abstract An exceedingly small number of high‐pressure polymorphs have been discovered in lunar samples. This situation does not seem to reconcile with the prolonged, intense bombardment surface, which should produce suitable conditions for formation such polymorphs. Here we report discovery reidite, a polymorph ZrSiO 4 scheelite structure meteorite Sayh al Uhaymir (SaU) 169. The reidite occurs mainly as lamellae hosted within zircon, likely corresponding deviatoric‐dominated transformation....
Chang'e-5 (CE-5) basalt, the youngest lunar basalt sample collected so far, is crucial for unraveling mechanism of prolonged volcanic activity on Moon. To better understand petrogenesis this it necessary to determine its eruption duration accurately. Previous PbPb age measurements have yielded a wide range from 2040 Ma 1963 Ma. This large may be attributed 80 million-year multi-eruption, analytical or interpretational biases different laboratories, disturbances in UPb system. Here, we...
