Regents LAB Review
3 Stations @ 9 minutes for each station
1) Properties of one mineral Classification of two rock samples
2) Epicenter Location
3) Elliptical Orbit
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
