Geochemical Reservoirs

The primary geochemical cycle of the solid Earth is directly associated with plate tectonics and mantle convection it is illustrated schematically in Figure 12.1. This is a box model in which the principal geochemical reservoirs are included. These are the core, the mantle, the oceanic crust, the continental crust, the oceans, and the atmosphere. In terms of the formation of the Earth, the mantle was the primary reservoir. The core was formed by the differentiation of the dense iron-rich...
