Why It Matters: Rock Forming Minerals Geology

Minerals are classified in different ways based on the elements that they contain. Matter (elements) makes up the minerals and minerals make up rocks. We can’t understand rocks and rock forming process or some of the other areas of geology until we have a basic knowledge of minerals.

This process of formation of mineral deposits has been described as pyrometasomatism by Lindgren and as contact-metasomatism by Bateman. In this case, the enclosing country rock is altered by the heat and other chemical constituents of the invading intrusive magma forming new minerals under conditions of high temperature and pressure.

Rocks and minerals - British Geological Survey

Rocks are generally made up of two of more minerals, mixed up through geological processes. For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica as interlocked crystals; a sandstone is a sedimentary rock that can also contain quartz, feldspar and mica, but as grains compacted and cemented into each other.

As a result, rocks form quickly and mineral crystals are very small. Rhyolite is one type of rock that is formed when lava cools. It contains similar minerals to granite.
