Actively spreading mid-ocean ridges are places where young lithosphere is added to the edges of spreading, oceanic plates, and they are sites for submarine eruptions of basaltic lava. Terrigenous sediment coverings are very thin or absent. However, sediments at mid-ocean ridges do not typically include thick siliceous ooze deposits and sandy turbidite beds. These types of sediments are more commonly found in areas of slow deposition in the deep ocean or on continental shelves.
