Silt Stones
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility (geology), fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an Unconventional (oil & gas) reservoir, unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock (clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction i ...

Canadian Journal Of Microbiology
The ''Canadian Journal of Microbiology'' is a monthly peer-reviewed scientific journal covering all aspects of microbiology. It was established in 1954 and is published by NRC Research Press. The editors-in-chief are Kari Dunfield (University of Guelph) and Christopher K. Yost (University of Regina). The founding editor (serving from 1954 to 1960) was Robert George Everett Murray (1919–2022).
