Learn about the composition, geochemistry and life cycle of oceanic crust, the upper layer of the oceanic portion of the tectonic plates. Find out how oceanic crust is created, modified and destroyed at mid-ocean ridges, hotspots and subduction zones.
Learn about the outermost layer of Earth's lithosphere under the oceans, formed at spreading centres on oceanic ridges. Explore its layers, composition, structure, and how it differs from continental crust.
1 Ιαν 2018 · Learn about the basaltic composition, formation, and structure of the oceanic crust that covers most of the Earth’s surface. Explore the variations in major and trace elements, seismic layers, and sampling methods of the oceanic crust.
Learn about the thin, magnesium-rich layer of Earth's crust that forms at mid-ocean ridges and consists of basaltic rocks. Explore the seismic structure, geological interpretation and composition of oceanic crust based on ophiolites and drilling data.
Learn how oceanic crust is created at spreading ridges, composed of igneous and sedimentary rocks, and influenced by magnetic fields and plate tectonics. Explore the geology of seamounts, islands, and reefs on the sea floor.
24 Απρ 2024 · Learn how oceanic crust is formed, aged, and mapped using magnetic patterns and seafloor spreading. Explore the lithologies, volcanism, and sedimentation of the oceanic crust and its features.
1 Ιαν 2023 · Oceanic crust is the solid layer of the Earth beneath the oceans, composed of basalt and denser than continental crust. It forms by partial melting of mantle beneath mid-ocean ridges and has a layered structure and a variable age.
