文摘
- •
The Simplon Line is a relatively weak fault.
- •
Cataclasites nucleate along misoriented phyllosilicate-rich mylonitic foliation.
- •
High-angle Andersonian faults and fractures do not develop.
- •
Friction coefficient is μmyl<0.25, hence the SL is also an absolutely weak fault.
- •
The weakness of the SL is not related to the effect of fluids, but to phyllosilicates.
