Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Mantle plumes are buoyant upwellings of hot rock that originate deep within Earth's mantle near the core-mantle boundary and travel upward toward the crust, feeding intraplate volcanism and large igneous provinces.

The analysis

Multiple papers using seismic tomography, geodynamic modeling, and convection simulations demonstrate that mantle plumes rise from deep mantle boundaries (such as the core-mantle boundary or lower mantle anomalies) up to the Earth's crust, supporting the claim.
