Magma that has bubbled up through the crack in the Earth's surface.
While it is molten it is above the Curie temperature and is not magnetic, as it cools below this temperature the ambient magnetic field becomes "frozen" into the basalt.

The color of rock that forms oceanic crust at mid-ocean ridges is usually dark gray to black. The type of rock is basalt, which is rich in iron and magnesium and forms from solidified lava.
Basalt forms when lava cools and solidifies on the Earth's surface, often in volcanic regions. It is commonly found in areas with recent or ancient volcanic activity, such as volcanic islands or along mid-ocean ridges.
The molten material then spreads out, pushing the older rock to both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. Then more molten material flows into the crack. The material splits apart the strip of solid rock that formed before, pushing it aside.
Yes, basalt forms on oceanic crust through volcanic activity at mid-ocean ridges and hotspot volcanoes. It is the most common rock type on the ocean floor and is created from the solidification of molten lava.
Minerals are not classified as metamorphic. The mid-oceanic ridges are generally considered to be areas where new basaltic crust is formed from uprising magma. The basalt is considered an igneous rock in classification.
Basalt is extruded from volcanoes and MOR (mid ocean ridges). It actually forms in the earth's mantle and just solidifies on the earth's surface.
