Minerals from MetamorphismMinerals from Metamorphism

• Beneath Earth’s surface undergoing extreme heat and pressure.

• EX: Jade, Talc, and Garnet

Minerals from Molten RockMinerals from Molten Rock

Magma cools fast = small crystals

Magma cools slow = large crystals

Ex: Quartz, Felsdspar, Olivine

Minerals from Solution: Hot WaterMinerals from Solution: Hot Water

EX: Silver and Calcite

Minerals From Solutions: Minerals From Solutions: EvaporationEvaporation

Ex: Halite, Salts

Mining for MineralsMining for Minerals

• Drill: What is the difference between iron and iron ore?

• Objective: SWBAT identify methods of mining in order to determine the most efficient method for mining certain minerals.

• HW: 2-2 and 2-3 due Thursday.

Which method to useWhich method to use

• Coal: Usually found in large amounts close to the surface.– Open Pit

• Gravel: Found near structurally unstable overburden (rock not wanted). Found in large quantities.– Strip mine

• Iron: Found deep within the ground near hard, dense rock. Can be found as veins. – Shaft Mine

Identifying MineralsIdentifying Minerals
