15 | Siltstone is a fine grained clastic sedimentary rock and composed of [[silt>>doc:Environmental Surveys.Rock types.Sedimenten.Silt.WebHome]]-sized particles. It forms in silt deposits where silt-particles are cemented into a rock. Silt-size particles can be found close to mud and [[sand>>doc:Environmental Surveys.Rock types.Sedimenten.Sand.WebHome]] deposits. It is the intermediate level of size between sand and mud. | ||

17 | The most common environments in which is formed are therefor: fluvial, aeolian, tidal, coastal, lacustrine, deltaic, glacial, paludal and shelf environments. Sedimentary structures such as layering, cross-bedding, ripple marks, erosional contacts, and fossils provide evidence of these environments. [[[1]>>url:https://geology.com/]] | ||

20 | Siltstone has usually a gray, brown or reddish brown color with a white streak. It can vary from this color by weathering or due to a composition of the cement this can give a various amount of extra colors. Siltstone is composed of quartz and clay minerals and due to these composition it has an hardness of 6.5 on the Mohr scale. | ||
