Solution

Sure, here are some examples of rocks that solidified within Earth's crust:

  1. Granite: This is a common type of intrusive, felsic, igneous rock which is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy.

  2. Diorite: This is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar, biotite, hornblende, and/or pyroxene.

  3. Gabbro: This is a phaneritic (coarse-grained), mafic intrusive igneous rock. It is the most abundant rock in the deep oceanic crust and can be very diverse in composition.

  4. Peridotite: This is a dense, coarse-grained igneous rock, consisting mostly of the minerals olivine and pyroxene. It is an important rock type because the Earth's mantle is predominantly composed of it.

  5. Quartz Diorite: This is an intrusive igneous rock similar to diorite, but containing a larger amount of quartz.

These rocks all solidify within the Earth's crust from magma, which is why they are known as intrusive igneous rocks.
