Magnesium-iron replacement in clay minerals in anoxic marine sediments |
|
| Authors: | Drever J I |
| Abstract: | In anoxic marine sediments iron is extracted from clay minerals to form a sulfide. Magnesium from the surrounding solution then replaces the extracted iron in the clay mineral structure. This process removes magnesium from seawater and serves as a control on the composition of interstitial waters in sediments. |
