Rocks and the Rock Cycle - legacyjr.net - YUMPU Which descriptive word applies to an igneous rock that is high in feldspar and quartz? The great majority of the igneous rocks are composed of silicate minerals (meaning that the basic building blocks for the magmas that formed them are made of silicon [Si] and oxygen [O]), but minor occurrences of carbonate-rich igneous rocks are found as well. Rocks heat up and cool off, which makes them expand and contract. Whereas sedimentary rocks are produced by processes operating mainly at Earths surface by the disintegration of mostly older igneous rocks, igneousand metamorphicrocks are formed by internal processes that cannot be directly observed and that necessitate the use of physical-chemical arguments to deduce their origins.

Miners mine diorite to use as crushed stone and as the base for the construction of things like buildings and parking areas. On the other hand, magma erupted at the surface is chilled so quickly that the individual minerals have little or no chance to grow.
