The shallow planar rock slide triggered due to the highly jointed nature of quartzite, percolation of rain water through joint planes leads to weathering and widening of joints, which results in failure.

Removal of loose and protruded rock fragments at critical angle from slope face.
1. Highly fractured quartzite. 2. Weathering and widening of joint planes due to rain water percolation causing loosening of rock slabs along the joint planes.
