Drillers break into magma chamber: "It has been described as a geologist's dream - a unique opportunity to study up close the volcanic processes that built the Earth's continents.

Molten rock pushed back up the borehole several metres before solidifying, making it perfectly safe to study.
Magma specialist Bruce Marsh says it will allow scientists to observe directly how granites are made."
