A story of lithospheric plates

A story of lithospheric plates Whether plate tectonics began 850 million years ago or earlier is uncertain. FINGER-PT hypothesises that preservation bias obscures evidence of earlier modern-like tectonics. To test this, the project analyses detrital minerals in sedimentary rocks, employing experimental petrology, elastic barometry, and geochemistry to uncover when tectonic processes as we know them began.
