6% of our meteorites - on Earth - come from the famous Mars, Moon, Vesta trio. Those lack chondrules. We have now catalogued 70% others, of the noncarbonaceous chondrites: Karin, Koronis, Massalia.
Massalia makes up over half that 70%. This one spawned the L chondrites. Its breakup has been pinned to 466 Mya, that Ordovician mess, but also 40 Mya(?). Karin and Koronis sent H rocks down here, 5.7 and 7.6 Mya. Also see here.
Carbonaceous chondrites make up only 4.4% despite C asteroids being common up in actual Space - and delivering ruthenacious love to the dinosaurs. For this paucity, the papers blame... Earth: volatile-rich slushballs don't do well in our atmo. Also claimed: Ryugu and Bennu are basically the same, coming from the Polana breakup.
