♢ Student’s t-test was conducted between the meteorite and the soil substrates on Inv. Simpson with a p > 0.05 for both. Standard deviations are given in brackets.
∗Samples were subsampled to the library size of MA, which had the lowest number of sequences: 34871. ℵNames of all meteorites are still waiting official classification by the Meteoritical Bulletin.
