Types of Erosion
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz
Aluminium Oxide, Ca, NaCl, CaO, Iron(III) Oxide, MgO, Silicon Dioxide
Biological Weathering, Chemical Weathering, Mechanical Weathering
Coastal Erosion, Water Erosion
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides
Ca, CaO, Carbon Dioxide, KCl, MgO, Sulfur Dioxide, Sulphur
Cataclastic Metamorphism, Contact Metamorphism, Regional Metamorphism
Coastal Erosion, Water Erosion, Wind Erosion
