This site brings together photographs documenting the brittle faults on the road between Gangtok and Nathula Pass in Sikkim.

Fig. 1a) Nearly 2m thick fault rock and orthogneiss in hanging wall.

Fig. 1b) Same fault.	Fig. 1c) Same fault.
Fig. 1d) Same fault showing curved foliation on the handing wall.	Fig. 1e) Brittle faults associated with dragging in gneiss suggesting brittle overprint of ductile shearing
Fig. 1f) fault gouge in two bands	Fig. 1g) Brittle faulting.
Fig. 1h) Fault gouge only 2cm thick.	Fig. 1i) A cataclasite layer 1 cm thick.
Fig. 1j) Fault gouge only 2cm thick.	Fig. 1k) A cataclasite layer 1 cm thick.
