The scientists studied the behaviour of a pure iron carbonate, FeCO3 (called siderite), at extreme temperature and pressure conditions covering the entire Earth's mantle, meaning over 2500 K and ...

Annual carbon flux estimates from the iron-fertilized Crozet bloom were used to quantify the carbonate counter pump effect in reducing CO 2 drawdown to the ocean interior. To achieve this we ...

Upper mantle carbonates are magnesium-rich and iron-poor. Under lower mantle conditions, it is thought that the arrangement of electrons in carbonate minerals changes under the pressure stress in ...

Carbonates are a group of minerals that contain the carbonate ion (CO32-) and a metal, such as iron or magnesium. Carbonates are important constituents of marine sediments and are heavily involved ...

Washington, D.C.-- Carbonates are a group of minerals that contain the carbonate ion (CO32-) and a metal, such as iron or magnesium. Carbonates are important constituents of marine sediments and ...
