Re:Mining (Score 1)

I somehow missed the Sci News article, but I just cannot see how there would by much concentration of minerals as a results of, say, about 200 million years of *possible* plate tectonics, verses, oh about 3.5 billion years on earth. In maps of Mars I don't see subductions zones, "island arcs", uplifts with erosion that would expose minerals, etc. As far as Mascons, the Moon has mascons also. They could just be lumps of iron from impacts.
