Introduction to Rocks and Minerals
Understanding the basics of geology starts with differentiating between rocks and minerals. These natural substances form the foundation of Earth's crust and play crucial roles in its geological processes.
What Are Minerals?
Minerals are naturally occurring inorganic substances with a definite chemical composition and crystalline structure. They are the building blocks of rocks.
Key characteristics of minerals include:
- Solid state at room temperature
- Inorganic origin
- Crystalline structure
- Defined chemical composition
- Specific physical properties (color, luster, hardness, cleavage, etc.)
What Are Rocks?
Rocks are aggregates composed of one or more minerals. They are classified based on their formation process into three main types:
- Igneous Rocks: formed from cooled and solidified magma or lava.
- Sedimentary Rocks: formed from the accumulation and compaction of mineral and organic particles.
- Metamorphic Rocks: formed when existing rocks are transformed by heat, pressure, or chemically active fluids.

Key Topics Covered in Rocks and Minerals PDFs
A typical geology PDF on rocks and minerals includes detailed sections on various topics, such as:
Mineral Identification and Properties
Understanding physical and chemical properties aids in identifying minerals.
Common mineral properties include:
- Color
- Luster (metallic or non-metallic)
- Hardness (Mohs scale)
- Cleavage and Fracture
- Streak
- Specific gravity
Tools used for mineral identification include:
- Hand lens or microscope
- Hardness tester
- Streak plate
Classification of Rocks
A detailed classification system helps in understanding the origin and properties of rocks.
- Igneous Rocks:
- Intrusive (plutonic): Granite, Diorite, Gabbro
- Extrusive (volcanic): Basalt, Rhyolite, Andesite
- Sedimentary Rocks:
- Clastic: Sandstone, Shale, Conglomerate
- Chemical: Rock salt, Gypsum
- Organic: Coal, Chalk
- Metamorphic Rocks:
- Foliated: Slate, Schist, Gneiss
- Non-foliated: Marble, Quartzite
Geological Processes and Rock Cycle
Understanding how rocks transform from one type to another through processes like melting, cooling, erosion, sedimentation, and metamorphism.
