Welcome. It’s an interesting subject, but I don’t think the pay to read papers would expand much beyond the abstracts since much of the debate was of the algae vs. fungus sort.

If I understand what was done it is similar to what I’ve found when buried metal has corroded away in the ground. One can still analyze the soil and find chemicals left behind that are unique to that particular mixture of metals even though traces of each occur naturally all over.
Ir’s not metal any more but neither is it just enriched soil.
Similar, I say, not exactly the same.
