WebThus, geodynamic models are needed to provide insight into the processes that control the formation of new crust and hydrothermal circulation at mid-ocean ridges. These models allow us to test governing parameters and investigate physical hypotheses and conceptual models derived from geological, geophysical, and geochemical observations. During ...
