Study Notes
Mineral Properties
- Minerals are naturally occurring, solid, inorganic substances with a defined chemical composition and crystalline structure.
- Hardness refers to a mineral's resistance to scratching.
- Cleavage describes how a mineral breaks along specific planes of weakness.
- Fracture describes how a mineral breaks irregularly, without a defined pattern.
- Tenacity refers to a mineral's resistance to bending, crushing, or tearing.
- Luster describes how light reflects off a mineral's surface.
- Streak is the color of a mineral's powder.
- Crystalline solids have a highly ordered, repeating arrangement of atoms.
- Metallic minerals typically have a shiny, metallic luster and are good conductors of electricity.
- Mohs Hardness Scale is used to measure a mineral's hardness.
Mineral Classification
- Minerals can be categorized based on their chemical composition (e.g., silicates, carbonates, sulfides, oxides).
- Silicates are the most abundant mineral group and contain silicon and oxygen.
- Sulfides are minerals containing sulfur and a metal.
- Carbonates contain the carbonate ion (CO3)2−
- Halides contain elements like fluorine and chlorine.
- Oxides contain oxygen and a metal.
Rock Formation
- Igneous rocks form from the cooling and crystallization of magma or lava.
- Sedimentary rocks form from the accumulation and cementation of sediments.
- Metamorphic rocks form when existing rocks are transformed by heat and pressure.
- Mineral deposits form through various geological processes, including crystallization from magma, precipitation from water, and weathering and erosion.
Mineral Cleavage Types
- Perfect cleavage describes a mineral that breaks cleanly along its cleavage planes.
- Prismatic cleavage produces long, narrow cleavage planes.
- Rhombohedral cleavage breaks into rhombohedral shapes.
- Octahedral cleavage produces eight-sided cleavage planes.
- Basal cleavage breaks into flat sheets.
- Cubic cleavage breaks into cubes or rectangular blocks.
- Minerals that fracture break irregularly, showing no cleavage.
