- Abstract
A 1130 °C) to cause partial frictional welding of the deformed quartzitic bedrock beneath an ice-loaded clast. These results support suggestions that glacial seismicity is due to episodic very rapid shifts of large ice masses over the substrate (stick-slip movement). They also indicate that significant effective normal stresses occur at the base of glaciers.
