The low permeability of shale and clay keeps water in the vicinity of plant roots, so, in general, shale and clay will support dense vegetation. Today it is used as an excellent building material. Siltstone is generally formed adjacentto sandstone deposits – ie close to beaches and delta edges where sand isdeposited.

Siltstone is a sedimentary rock which has a composition intermediate in grain size between the coarser sandstones and the finer mudstones and shales. [17] Among proposed mechanism are glacial grinding;[18][19] weathering in cold, tectonically active mountain ranges;[17] normal weathering, particularly in tropical regions;[10][20][21] and formation in hot desert environments by salt weathering. silt grains are large enough for most people to see without using a magnifying Found beneath the coarse alluvium/colluvium quality. Silt is the product of physical weathering, such as freezing and thawing. See also siltstone. Display more examples. Suggest an example.

Structure: Shale can form thick, dense deposits, but shale response to tectonic forces Whereas thin layers of the claystone found on the top and mostly in between siltstone layers. The low porosity of Siltstone renders it useless as an oil or gas reservoir. Silt is believed to be the product of physical weathering, which can involve freezing and thawing, thermal expansion, and release of pressure. This unit is underlain by 50 cm of highly fractured, reddish brown siltstone. shale, is often misidentified and labeled as shale by engineers. broken to observe grain size. If you find a claystone, you know that it accumulated in a very quiet environment with almost still water. Where Is Siltstone Found?
