In geology, the classic definition of a mineral is: 1) naturally occurring, 2) inorganic, 3) solid at room temperature, 4) regular crystal structure, and 5) defined chemical composition. Some natural substances technically should not be considered minerals, but are included by exception. For example, water and mercury are liquid at room ...
The most significant difference between feldspar and quartz is that feldspar is a group of minerals, and quartz is an individual mineral. When comparing specific specimens in the feldspar group to quartz, the differences found have to do with: Formation. Hardness.

While quartz is the most abundant mineral on the Earth's surface, due to its durability, the feldspar minerals are the most abundant minerals in the Earth's crust, comprising roughly 50% of the total minerals that make up the crust. Figure 3.29: Pink orthoclase crystals.

Minerals are naturally occurring, inorganic solids with a definite chemical composition and a crystal lattice structure.

Hematite, on the other hand, is an example of a mineral for which color is not diagnostic. In some forms hematite is deep dull red, but in others it is black and shiny metallic (Figure (PageIndex{2})). Many other minerals can have a wide range of colors (e.g., quartz, feldspar, amphibole, fluorite, and calcite).
identifying quartz. Feldspars are an important group of silicates and the most common minerals in the crust of the earth. There are two kinds of feldspar - the potassium feldspars such as orthoclase (also known as K-spar), and the sodium-calcium feldspars collectively called plagioclase. All feldspars have two cleavage directions.

by segregation of minerals into different layers. In most gneisses, equi-dimensional mineral grains of quartz and feldspar are more abundant than the platy micas. Non-foliated metamorphic rocks include marble, quartzite, and hornfels (a fine-grained, hard rock). Some of the lab manuals in lab have more complete descriptions of metamorphic rocks.
The same mineral may also be found in different colors. Figure below shows one sample of quartz that is colorless and another quartz that is purple. A tiny amount of iron makes the quartz purple. Many minerals are colored by chemical impurities. Purple quartz, known as amethyst, and clear quartz are the same mineral despite the different colors.
