However, in a case where magma does not have enough silica relative to the magnesium oxide to produce the pyroxene, the magma will compensate by making a magnesium-olivine (forsterite; Mg2SiO4), along with the pyroxene, since the olivine requires only one-half as much silica for every mole of magnesium oxide. It correctly identifies the following crystallization process of magma differentiation in metamorphic rock: olivine, pyroxene, amphibole, and biotite. Similarly, sedimentary rocks form in another step as sediment piles up and compacts, cementing the rocks in place. Give Every Student a Summer Book.

In one step, magma cools and crystallizes under the earths crust, forming intrusive igneous rocks. The former case usually occurs in subsilicic rocks that characteristically will have silicate minerals like magnesium-olivine, sodium-nepheline (NaAlSiO4, which requires only one mole of silicon for every mole of sodium [Na]), and leucite (KAlSi2O6, which requires only two moles of silicon to one mole of potassium [K]).

As a result, the rock is either composed of minerals that can be seen only with the aid of a microscope (called aphanitic, from the Greek aphans, meaning invisible) or contains no minerals at all (in the latter case, the rock is composed of glass, which is a highly viscous liquid). 0 After a long period of high pressure and heat, igneous and sedimentary rocks buried deep in the crust change into metamorphic rocks. There are four questions at the end of the lab that will review crystallization, intrusive and extrusive rocks. copyright 2003-2023 Study.com.
