occurring over a range of depths. Development of this conceptual model was based on …

Carbon budget of Earth's deep mantle constrained by petrogenesis of silica-poor ocean island basalts

C Sun, R Dasgupta - Earth and Planetary Science Letters, 2023 - Elsevier
The convecting mantle is the Earth's largest carbon reservoir that controls the carbon outflux

Three-dimensional magnetic stripes require slow cooling in fast-spread lower ocean crust

SM Maher, JS Gee, MJ Cheadle, BE John - Nature, 2021 - nature.com
Earth's magnetic field is recorded as oceanic crust cools, generating lineated magnetic
anomalies that provide the pattern of polarity reversals for the past 160 million years. In the …
