Presentation Transcript

Destructive Plate Margins:

Continental-Continental collision

Features/landforms:

  • Fold mountains

  • Thrust faults

  • Negligible volcanism

  • Regional metamorphism

  • Shallow focus earthquakes (SFQ)

  • Gneiss

  • Thickening of crust

Processes:

  • Mountain Building (Orogenesis)

  • Folding

  • Faulting

  • Metamorphism

  • Crustal Thickening



What are the main differences between

Continent-Continent Collision and

Oceanic-Oceanic/Oceanic–Continental Collision ?

Continent-Continent

Oceanic/Continent

Negligible volcanism

Volcanoes = andesitic rock

Shallow Earthquakes

Deep and Shallow Earthquakes

Extensive granite generation and regional metamorphism

Minor granite generation and localised metamorphism

Extensive shortening of continental crust – associated thrust faulting

Extensive shortening of oceanic crust – localised thrust faulting


Conservative Plate Margins:

Features/landforms:

  • Shallow focus earthquakes (SFQ)

  • Fault scarps

  • Lateral fault movement

  • Tear/wrench fault (Strike/Slip)

  • Fault zone

  • San Andreas Fault

Processes:

  • Lateral plate movement

  • Pressure build up

  • Stress release

  • Fault Displacement
