What are the 5 properties of minerals?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
What are the two 2 major properties of minerals?
A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical properties such as cleavage and hardness.

What is the classification of minerals?

What are minerals and their examples?
A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes. Examples include quartz, feldspar minerals, calcite, sulfur and the clay minerals such as kaolinite and smectite.
What are the 3 most common minerals?
The feldspar-group, a very complex mixture of oxygen, silicon, aluminum and trace elements like sodium, potassium, calcium and more exotic elements like barium, are by far the most common minerals, making up almost 58% of all to a geologist accessible rocks, especially magmatic and metamorphic ones.
