  • This diagram shows the mechanics of silicification through dissolution of rock materials and precipitation of silica. Silica enriched fluids are usually supersaturated with silica so that when they seep into voids, silica precipitate out. On the other hand, these fluids are relatively undersaturated with other rock minerals, which leads to a dissolution of the minerals. These materials are carried away by the fluids and are replaced by silica.
