What is meant by the term "rock forming minerals"?

Answer 1

Rock forming minerals are those found on Bowen's Reaction Series that form igneous rocks. They include mafic minerals (olivines, pyroxenes, amphiboles and biotite micas) and felsic minerals (feldspars, alkali micas and quartz). Usually they are called "common rock forming minerals" since they are found in most of the igneous rocks on Earth.

Answer 2

Rock forming minerals are the minerals whose presence leads to the classification of a rock, usually igneous in origin. Quartz, for example, is one of the basic building blocks of many igneous rocks. Feldspar is another. Still another is hornblende. Minerals such as those of the mica family are generally not thought of as rock forming minerals, because their presence or absence in a rock does not change the type of rock it is. The garnet family is another common non-rock forming mineral, for the same reason. Bear in mind that almost any mineral can form a rock in a specific thermochemical environment, but some are relatively unimportant in the grand scheme of things.

Answer 3

Minerals that tend to form rocks. Rocks are made out of mineral particles. For example, chert is a rock made of tiny quartz grains. Granite is a rock that is made up of feldspar, quartz, pyroxene, and mica minerals.

Answer 4

a rock is a hard formatin a firm support a form is configuration of a mold type or convention method to mold or shape and mineral is natually ocurring of inorganic matter so what this means is a hard formation molded of a naturally man made material like stones for example the salt you see hanging in caves that is a inorganic matter hope this helps ya out better

Answer 5

minerals that form into rocks. kinda like quartz and quartzite
