Rocks formed by the cooling of magma from the spreading ridge that push across the sea just to be submerged by the continental plates. It's igneous rock.
rock that makes up coninental Crust
Granitic rock forms the majority of the continental crust.
The light colored rock that makes up most of the continental crust is granite. It is a coarse-grained igneous rock composed mainly of quartz and feldspar minerals. Granite is less dense than the dark basaltic rock that makes up oceanic crust.

Igneous rock comprises the majority of Earth's crust.
Granitic rock forms the majority of the continental crust.
The light-colored rock that makes up the continental crust is called granite. Granite is a coarse-grained igneous rock composed mainly of quartz, feldspar, and mica. It is less dense and more buoyant than the darker basaltic rock that makes up the oceanic crust.
The solid rock layer of the Earth is known as the crust, which is the outermost layer of the planet. The crust is divided into two types: continental crust, which makes up the continents, and oceanic crust, which makes up the ocean floors. The thickness of the crust can vary, with continental crust being thicker than oceanic crust.

Basalt !! :)
The rock that makes up oceanic crust is primarily basalt. Basalt is a fine-grained, dark volcanic rock that forms from the cooling and solidification of molten lava at or near the Earth's surface.
