Seismology: Talc at fault
Christopher Wibberley1
Abstract
The behaviour of the San Andreas fault varies along its length — it slips in some places and creeps in others. The discovery of the ultrasoft mineral talc in rocks from deep inside the fault could help to explain why.
Faults are puzzling beasts. The strength of faults, the largest of which are boundaries between Earth's tectonic plates, has been mired in controversy ever since plate tectonics properly arrived on the scene in the 1960s.
