Smaller meteorites greater abundance
Webb18 dec. 2024 · In bigger meteorites, melting begins at the meteorite surface, and as soon as the surface liquid reaches a critical depth, the liquid falls away as drops. This prediction suggests that the fusion crust on a meteorite should be also limited in thickness, and meteorites should also show imprints on the surface matching the size of the liquid … Webbon meteorites as O 18/O 16 is greater. ∴ Let O 18(100−x+2) i.e., 100−cn−2%. ∴O 16% be x−2.

This corresponds to about 4.5 billion years ago, when the CAIs found in meteorites formed. “The fact that our solar system has aluminum-26 might not be unique or special,” Gaches says.
