摘要
模拟月壤是与月球月壤具有相似的矿物组成、化学成分和物理力学性质的地球物质,是月球样品的地球化学复制品。长白山龙岗火山群金龙顶子火山喷发的四海火山渣具有与阿波罗14号采集的月球样品相似的化学和矿物组成,并含有20%~40%的玻璃物质。以四海火山渣为初始物质,研制成功CAS-1模拟月壤,并测量了CAS-1模拟月壤的主量和微量元素组成、矿物组成、密度、颗粒形态、粒度分布、抗剪性和复介电常数等参数。结果表明,CAS-1模拟月壤与Apollo 14号采集的月球样品具有相似的化学成分、矿物组成和物理力学性质,是一种理想的低钛玄武岩质模拟月壤。
Lunmar soil stimulant is a kind of geological material, which has similar mineral and chemical compossition, similar physical and mechanical properties with lunar surface material. It is a geochemical copycat of lunar regolith. Scoria erupted by Jinlongdingzi Volcano, which is located in Longgang Volcano Groups in the western foot of Changbai Mountain in Huinan County, Jilin Province, were found to have similar mineral and chemical composition with lunar regolith sampled by Apollo 14 astronaut. Like lunar regolith, there are 20 - 40 wt. % glassy material in Jinlongdingzi scoria. Using Jin- longdingzi scoria as pristine material, authors developed a new lunar soil stimulant-CAS-1. We also measured the relative parameters of CAS-1 lunar soil stimulant, such as major chemical composition and trace element, mineral composition, density, particle shape and particle size distribution, shear strength, complex dielectric constant et. al.. CAS-1 is an ideal low titanium lunar soil stimulant, which has similar mineral and chemical composition, and similar physical mechanical properties with lunar regolith sampled at Apollo 14 landing site.
