AQA Environmental Science Lithosphere

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.

Intrusions and fissures away from a batholith

Superheated pressurised water

Fractional crystallisation

Sedimentation

Evaporites

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

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.

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

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
