SUMMARY:Mt Erebus\, Antarctica\; Understanding the world's
  southernmost active volcano - Yves Moussalllam

DESCRIPTION:Mt Erebus\, the world southernmost active volcano 
 represent a unique natural laboratory to study the
  dynamic of magma in the near surface. In the crat
 er of this ~4 km high volcano is a persistently ac
 tive lake of molten 960°C lava periodically pertur
 bed by Strombolian eruptions. A peculiar feature o
 f this lava is the presence of very large crystals
  up to 7 cm long. These crystals display two inter
 esting properties: perfect growth zoning and large
  inclusions of fossilised melt pocket. By comparin
 g the natural crystals to synthetic ones grown in 
 the laboratory we can decode the information locke
 d in each crystal and track back its history of ci
 rculation up and down the magmatic conduit.
