What is Mineralogy?
- Mineralogy is the study of minerals, which are the building blocks of rocks.
- A mineral is a naturally occurring inorganic solid with an orderly crystalline structure and a definite chemical composition.
Characteristics of Minerals
- Minerals are naturally occurring, formed by natural geological processes.
- Minerals are inorganic, unlike organic compounds made by living things.
- Minerals are solids, unlike liquids or gases.
- Minerals have an orderly crystalline structure, unlike amorphous substances.
- Minerals have a definite chemical composition, with some variation allowed.
Properties of Minerals
- Optical properties include:
- Luster: the appearance or quality of light reflected from the surface of a mineral.
- Color: the wavelength of light reflected from a mineral surface, but not a reliable diagnostic property.
- Streak: the color of a mineral in powder form, obtained by rubbing it across a streak plate.
- Transparency: the ability to transmit light, with some minerals being opaque, translucent, or transparent.
- Crystal shape or habit: the common or characteristic shape of individual crystals or aggregates of crystals.
- Strength properties include:
- Hardness: the resistance of a mineral to abrasions or scratching, measured using the Mohs scale.
- Cleavage: the tendency of a mineral to break or cleave along planes of weak bonding.
- Fracture: the way a mineral breaks when stressed, with some producing uneven surfaces or conchoidal fractures.
- Tenacity: how a mineral responds to stress, with some being brittle, malleable, sectile, or elastic.
Diagnostic Properties of Minerals
- Luster, streak, and hardness are useful diagnostic properties for identifying minerals.
- Color is not a reliable diagnostic property, as it can vary among different specimens of the same mineral.
- Crystal shape or habit can be helpful in identification, but not always.
- Other properties, such as taste, feel, smell, and optical properties, can also be used to identify minerals.
Identifying Minerals
- Mineral identification involves analyzing a combination of properties, including optical, crystal shape, and strength properties.
- Chemical tests, such as the acid test, can be used to detect the presence of certain minerals or elements.
Mineral Groups and Classification
- Over 4,000 minerals have been named, but only a few dozen are abundant and make up the majority of the Earth's crust.
- These abundant minerals are called rock-forming minerals, and they are used extensively in manufacturing products.
- Eight elements make up the majority of rock-forming minerals: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
Silicates
- Silicates are the most common mineral group, making up over 90% of the Earth's crust.
- They contain oxygen and silicon atoms, and may include additional elements such as iron, magnesium, potassium, and calcium.
- The silicon-oxygen tetrahedron is the fundamental building block of silicates, consisting of four oxygen atoms bonded to a single silicon atom.
- Silicates can be classified into different groups based on their structure and composition, including:
- Feldspars: the most abundant mineral group, comprising about 51% of the Earth's crust.
- Quartz: the second most abundant mineral in the crust, consisting entirely of silicon and oxygen.
- Micas: a group of minerals that cleave easily in one direction, including muscovite and biotite.
- Pyroxenes: a group of diverse minerals that are important components of dark-colored igneous rocks.
- Olivine: a family of high-temperature silicate minerals that are black to olive green in color.
Non-Silicates
- Non-silicates are a smaller group of minerals that make up about 8% of the Earth's crust.
- They are typically divided into groups based on the negatively charged ion or complex ion they contain.
