Geomorphological features such as weathering pits tafoni honeycomb structures polygonal cracks flared slopes exfoliation and boulders are observed. The metamorphism causes mineral alignments that affect the strength of the rock. The studied rocks have high strength in perpendicular direction to foliation.

2019 6 1 Little may be gained from attempting to differentiate between geologic weathering and soil formation because both are weathering processes. It may be possible to infer that a material was weathered before soil formation. The weathering process causes some bedrock constituents to be lost some to be transformed and others to be concentrated.
