Modeling the thermal state of the oceanic crust

New ocean crust is created every year along the mid-ocean ridge system, which is one of the most active plate boundaries on the Earth's surface. Studying the magmatic and tectonic processes of the construction of new oceanic crust at mid-ocean ridges is important for understanding the structure...

Description
Summary:New ocean crust is created every year along the mid-ocean ridge system, which is one of the most active plate boundaries on the Earth's surface. Studying the magmatic and tectonic processes of the construction of new oceanic crust at mid-ocean ridges is important for understanding the structure of oceanic crust and the evolution of the oceanic lithosphere. This review focuses on modeling the thermal state of the oceanic crust and its links to various seafloor observations such as ridge axis topography, gravity, and seismic crustal structure. Thermal modeling is important because the crustal thermal structure of a spreading ridge not only controls the rheology of the oceanic lithosphere and the ridge topography but also determines the style of oceanic crustal genesis, by a long-lived magma lens or by episodic magma intrusions.
