The economic importance of rocks and minerals has to do with how rocks and minerals are important to what we use daily. For example, I know the rock slate is used primarily for chalks.

Metamorphic rocks are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which the original rock was formed. This process is called metamorphism, meaning to "change in form".The result is a profound change in physical properties and chemistry of the stone.

Diorite is said to be an intrusive rock that occurs in the hues of gray. It is formed from the magma that cools under the surface of the Earth. We provide you with information regarding the origin, facts, and properties, and uses of diorite rock.

Extrusive rock, any rock derived from magma (molten silicate material) that was poured out or ejected at Earth’s surface. By contrast, intrusive rocks are formed from magma that was forced into older rocks at depth within Earth’s crust; the molten material then slowly solidifies below Earth’s surface, where it may later be exposed through erosion.

'rock' and λόγος, lógos) is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together because they both contain heavy use of chemistry, chemical methods, and phase diagrams.

Introduce students to different types of rocks and their uses. Background Information: Rocks normally consist of several minerals, some essential, some accessory. A rock may be thought of as a "mineral environment." Each rock type was formed under certain specific conditions, resulting in the formation of a fairly predictable group of minerals.
