Complex Analysis Yields Simple Estimate of Carbon Dioxide Trapped in the Lithospheric Mantle

Carbon dioxide leaks that seep upward from Earth’s mantle into hydrocarbon reserves pose a problem for oil and gas companies because contaminated reserves are more expensive to harvest and process. The carbon dioxide initially enters the mantle through carbonates held in Earth’s crust, which sinks into the mantle at the edges of tectonic plates, due to the force of their collision. While some of the gas returns to the surface through volcanic eruptions, an unknown amount of carbon dioxide stays trapped in the lithosphere, Earth’s rocky crust and upper mantle.
