What are GREY rocks made of?

Sedimentary rocks such as limestone or shale are hardened sediment with sandy or clay-like layers (strata). They are usually brown to gray in color and may have fossils and water or wind marks. Metamorphic rocks such as marble are tough, with straight or curved layers (foliation) of light and dark minerals.

Which rock type is dark in color?

A rock that has a large amount of ferromagnesian minerals in it will be a dark-colored rock because the ferromagnesian minerals (other than olivine) tend to be dark-colored; an igneous rock that is dark in color is called a mafic rock (“ma-” comes from magnesium, and “fic” from ferric iron).

What rock is intrusive?

intrusive rock, also called plutonic rock, igneous rock formed from magma forced into older rocks at depths within the Earth’s crust, which then slowly solidifies below the Earth’s surface, though it may later be exposed by erosion. Igneous intrusions form a variety of rock types.
