AQA Environmental Science Lithosphere

Igneous Rock

• Created by the cooling and hardening of magma or lava

• Created by minerals settling out, deposited and cemented.

• Created by existing rocks being subjected to immense pressure and temperature

• Created by minerals in solution, then water evaporating.

Metamorphic rock

• Created by the cooling and hardening of magma or lava

• Created by existing rocks being subjected to immense pressure and temperature

• Created by minerals settling out, deposited and cemented.

• Created by minerals in solution, then water evaporating.

Sedimentary Rock

• Created by existing rocks being subjected to immense pressure and temperature

• Created by minerals settling out, deposited and cemented.

• Created by the cooling and hardening of magma or lava

• Created by minerals in solution, then water evaporating.

Hydrothermal deposition includes? (more than one)

• Intrusions and fissures away from a batholith

• Superheated pressurised water

• Fractional crystallisation

• Sedimentation

• Evaporites

Evaporite are

• Minerals produced by isolated seas and water has been removed.

• Minerals transported in solution and then deposited as their oxidation state changes.

• Minerals produced by biological organisms

• Minerals produced by high heat and pressure

Alluvial deposits are

• minerals dissolved in solution and deposited depending on their oxidative state.

• produced by high heat and pressure

• produced by evaporation of seawater leaving crystals behind

• carried and separated out by flowing water.

Secondary enrichment involves

• minerals dissolved in solution and deposited depending on their oxidative state.

• Biological processes

• Seas becoming isolated and water evaporating leaving crystals behind

• Water flowing at different velocities, depositing minerals depending on density

Lasky's Principle

• as the purity of the mineral increases the cut off or grade increases

• as the purity of the mineral decreases cut off ore grade decreases

• as the purity of the mineral increases the amount increases exponentially

• as the purity of the mineral decreases, the amount increases exponentially

The point where mineral deposits that are too low for economic extraction

• Lasky's principle

• Cut Off Ore Grade
