Recently, a scientist put forward a new idea: the movement of the earth's plates should not be later than 3.5 billion years ago. His basis is that plate movement will inevitably transform the dark dark magnesite rocks in nature into light-colored felsic rocks. And 3.5 billion years ago, light-colored felsic rocks appeared on the earth. If the following are true, the expert's point of view is most questioned:. ['Light-colored felsic rocks are essentially "regenerated" from dark-colored magnesite rocks, and billions of years ago, magnesite rocks held an absolute quantitative advantage on the earth.', 'Analysis of sediment samples from 3.5 billion years ago around the world, containing less than half of the feldspar rock particles.', 'The interpretation of perilithic rocks in nature is much higher than that of magnesite rocks. The explanation seems to be only the plate motion, but the early plate tectonic movement is likely to be intermittent and local.', 'The earth was densely volcanic 3.5 billion years ago, and the magma released by the volcanic eruption will bury the magnesite rocks deep in the ground. These magnesite rocks will be melted and then transformed into lithic rocks. The only reason.']
