We will first discuss each of the physical properties that can be used, then develop a methodical approach to the identification of minerals using these physical properties. Among the properties we will discuss are: crystal habit, cleavage, hardness, density, luster, streak, color, tenacity, magnetism, and taste.

Geologists do the same thing, using specific properties to identify rocks and minerals. Geologists use the following tests to distinguish minerals and the rocks they make: hardness, color, streak, luster, cleavage and chemical reaction. He developed a hardness scale that helps to identify mineral properties.

Properties of Minerals

• Color.
• Crystal form.
• Hardness.
• Luster.
• Cleavage and fracture.
• Mineral classification systems.

2. Chemical properties of minerals show the presence and arrangement of atoms in minerals. Using their chemical properties, minerals are identified by how they react to certain substances.

Rock-forming mineral, any mineral that forms igneous, sedimentary, or metamorphic rocks and that typically, or solely, forms as an intimate part of rock-making processes.

Answer: Being able to identify minerals is important, because mineral identification is necessary to identify rocks and can be used to understand both the landscape and the geologic history of the area.

Minerals can be identified by their physical characteristics. The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification.
