Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that depleted mantle differs chemically and mineralogically from fertile or enriched mantle?

Yes. Depleted mantle is chemically and mineralogically distinct from fertile or enriched mantle, as evidenced by differences in partial melting residues, trace element ratios, and mineral phases.

The analysis

The claim states that depleted mantle differs chemically and mineralogically from fertile or enriched mantle. Papers 2 and 7 explicitly contrast depleted mantle (such as harzburgite residues) with fertile or enriched mantle sources, highlighting distinct chemical and mineralogical behaviors during melting and metasomatism. No papers refute this fundamental petrological concept.
