The moisture content of these materials tends to decrease with depth, and this is reflected in a rise in undrained cohesion values.

WebClay minerals are common weathering products (including weathering of feldspar) and low-temperature hydrothermal alteration products. Clay minerals are very common in soils, in fine-grained sedimentary rocks such as shale, mudstone, and siltstone and in fine-grained metamorphic slate and phyllite.
