Basalslip or sliding as it's often called, basically refers to the slipping or sliding of a glacier across bedrock, actually across a thin layer of water on top of the bedrock.
The distortion energy stored by twinning and the activation of non-basalslip are responsible for the nucleation and growth of dynamic recrystallization (DRX).
