What type of rock makes up most of the ocean floor?

"Mid ocean would be basaltic pillow lavas, continental shelves \ contain coquina limestones made from shells. There are some sites around the Bahamas that have exposed limestones derived in a former time from limey oozes/muds. All in all by a vast percentage would be basalt." http://answers.yahoo.com/question/index?qid=20090908165526AAraFxL that's my citation


What is the type of rock that oceanic plates are made of?

Oceanic plates are primarily made of basalt, which is a type of volcanic rock that forms from the cooling and solidification of magma on the ocean floor. Basalt is dark in color and has a fine-grained texture.


A mountain in the desert is found to be made from the remains of ancient ocean organisms Which type of rock makes up the mountain?

The mountain is likely made of sedimentary rock, such as limestone or sandstone, that formed from the accumulation and compaction of the remains of ancient ocean organisms over millions of years.


What is the color and type of rock that forms oceanic crust at mid-ocean ridges?

The color of the rock that forms oceanic crust at mid-ocean ridges is dark gray to black. The rock is primarily basalt, which is a type of igneous rock formed from the solidification of molten lava.


What is the color and the type of rock that forms oceanic crust at mid ocean ridges?

What rock type is most abundant in the crust of the ocean floors?

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.
