| Why this rock is probably not a meteorite:
The finder thought that this rock resembled lunar meteorite QUE
93069. It does, but many kinds of terrestrial rocks superficially
resemble lunar rocks. An impact of a meteoroid on the Moon both breaks
rocks apart and glues other rock fragments together. Most lunar meteorites
are breccias - rocks composed of bits and pieces of other rocks.
In the lunar meteorites, the light-colored grains are clasts of anorthosite
rocks and feldspar (anorthite) mineral grains.
|What is it?
The rock is not a breccia. It appears to be an igneous rock (crystallized
from a melt) that contains light-colored grains of some type of feldspar.
Like nos. 084 and 086,
it's a porphyritic volcanic rock because the light-colored mineral
grains are larger than the dark matrix.
