Mineral Properties

• Luster Metallic Non-metallic

• Cleavage Flat planes Fracture Uneven

• Streak Colored White/None

• Hardness Scratch-hard Not-soft

ROCK Identification

• Igneous Rocks– Large, interlocking crystals– Vesicular – gas pockets (holes)– Glassy

*Cooling rates affect texture

Igneous

• Granite – Interlocking Pumice - crystals vesicular

Igneous

• Obsidian - glassy

ROCK Identification

• Sedimentary Rocks– pieces/fragments of other rocks– Flat layers of particles– Fossils and shells– Ripple marks or mud cracks

*Cemented/glued together

Sedimentary

• Pieces of rocks – Fossils

glued together

Sedimentary

• Particles in flat layers:

Sedimentary

• Ripple marks

Sedimentary

• Mud cracks

ROCK Identification

• Metamorphic Rocks– Banding of crystals…. Foliation: “I see Stripes”

– Twisting or folding…. distortion

*Heat & Pressure

Metamorphic

• Gneiss – banding (“I see stripes”)

Metamorphic banding
