Mantle Convection May Explain Earth's Great Unconformity
scienceofficial.org
A Nature study proposes slow mantle convection uplifted continents before glacial erosion carved the Great Unconformity, a gap in the rock record spanning up to a billion years.

Researchers propose that slow churning in Earth’s mantle lifted continents for hundreds of millions of years, after which glaciers eroded the raised land and removed a vast span of rock record.
