The most abundant rock type in the ocean floor crust is basalt. This volcanic rock forms from the rapid cooling of lava at mid-ocean ridges and is a key component of oceanic crust. Basalt is typically dense and rich in iron and magnesium, distinguishing it from the continental crust, which is primarily composed of lighter granitic rocks.
