摘要: The glassy coating of lunar rock 12017 is enriched in 15 trace elements relative to the crystalline interior. It apparently consists chiefly shock-melted rock, somewhat richer rare earth and alkali metals than itself. glass has been contaminated by about 0.5 percent carbonaceous-chondrite-like material or, alternatively, a mixture 0.06 0.3 fractionated meteoritic approximately 10 local soil. glazing seems represent molten splashed from nearby meteorite impact not situ melting sudden increase solar luminosity.
