Rocks

There are three major types of rocks:

  1. Igneous
  2. Sedimentary
  3. Metamorphic

Igneous

  1. basalt (玄武岩)
    1. mid-ocean ridge basalt (MORB)
    2. oceanic island basalt (OIB)
  2. peridotite (橄榄岩)
  3. harzburgite (斜方辉橄岩)

Sedimentary

Metamorphic

Pyrolite (地幔岩)

A theoretical rock considered to be the best approximation of the composition of Earth’s upper mantle. It is constructed from basalts and peridotites.

  1. meteorite: 陨石
  2. chondrite: 球粒陨石
