Classic worldwide localities

  • Suizhou L6 chondrite meteorite that fell in the suburb of Suizhou City, Hubei Province, China

Field-hunting tip

Where it forms: In or adjacent to shock-melt veinlets in chondritic parts of a meteorite, P-T conditions of formation estimated to be 20-24 GPa and >1200 °C. If you start seeing ringwoodite, majorite, xieite in float, you are in the right ground. Typical habit: irregular grains. Train your eye for that shape before scanning the outcrop.
