Lithosphere Flashcards
Acid Mine Drainage
Rain falls on a spoil heap and H20 reacts with Pyrite (sulphur) to form H2SO4 (Sulphuric Acid)
Decreasing pH…
Increases the solubility of heavy metals
Stock
All Minerals that exist in the lithosphere
Resource
All the material theoretically exploitable
Reserve
Proportion of minerals that can be exploited now
Lasky’s Principle
The amount of Ore you find in 1m3 of rock
Resistivity
Use electricity to locate deposits on the basis that water conducts electricity
IR Spectroscopy
Use IR waves to locate deposits using knowledge of mineral characteristics - will they absorb/deflect
Magnetometry
Using magnetic pull to locate deposits - used for nickel, cobalt and iron
Gravimetry
Measures the density of rock and can then be used to identify deposit - igneous are dense
Seismic Surveys
Using sound to locate deposits by assessing reflection
