里斯(Ries)、拉普佩贾维(Lappajrvi)等地球上的冲击坑,在其周围广布着玻璃状的熔体。这些熔体有着共同特点:1.化学成份分布均匀;2.化学组成反映出靶岩性质;3.有些亲铁元素如Ir,Os和Re相对富集。核爆炸坑与冲击坑的成坑过程十分类似。因此,研究核爆炸熔体,玻璃体的元素地球化学特征,建立熔体母岩模式,对月球高地,月海熔岩进行分类来研究月壳演化过程,以及研究玻璃陨石母岩模型等具有重要意义。
Ries, Lappajrvi, and other earth craters are surrounded by glass-like melts. These melts share common characteristics: 1. The chemical composition is evenly distributed; 2. The chemical composition reflects the properties of the target rock; 3. Some pro-iron elements such as Ir, Os and Re are relatively enriched. Nuclear explosion pit and impact pit pit process is very similar. Therefore, it is of great significance to study the melt of the nuclear explosion, the elemental geochemical characteristics of the vitreous body, establish the melt parent rock pattern, classify the lunar highland and the lagoon to study the evolution of the crust, and study the parent rock model of the glassy meteorite.
