Illustration of carbon dioxide and nonvolatile trace element behavior in magmas at oceanic volcanoes. Each panel tracks the concentration of CO2 and a nonvolatile trace element during the ascent of magma for three hypothetical cases.

This figure depicts the distribution and forms of carbon inside Earth. Carbon has low solubility in mantle minerals; hence, it occurs primarily in the form of gas (red circles), fluids or melts (orange circles), and accessory solid phases (green circles), including diamonds (octahedra).
