Elemental Abundances of Moon Samples Based on Statistical Distributions of Analytical Data

The successful return of Chang’E-5 (CE5) samples urges the hot topic study Moon in geochemistry. elemental data analyzed moon reported literature were collected to determine abundances samples. Based on 2365 analytical records from ten missions Apollo, Luna, and CE5, 11 major oxides including Cr2O3, 50 trace elements Ti, P, Mn, Cr, 15 rare earth (REEs) Y are derived based statistical distributions normal, log-normal, additive log-ratio transformation, respectively. According value 13.5% CaO content, classified into two types, as low-Ca high-Ca samples, whose also calculated respectively methods used total With respect mid-ocean ridge basalt (MORB) Earth, (including Moon, low-Ca, samples) rich REEs, Th, U, Pb, Zr, Hf, Cs, Ba, W, Be poor Na, V, Cu, Zn terms their concentrations, enriched Cr depleted K, Rb, spider diagrams. CE5 sample is a type clearly Fe, Sc, Nb, Ta, Sr, Mg, Al, Ni concentrations relative or If compared with sample, REE, P.
