Definition
Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix
  
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt

Formation
Kenyte is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
  
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

Kenyte vs Siltstone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Kenyte vs Siltstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Kenyte and Properties of Siltstone. Learn more about Kenyte vs Siltstone in the next section. The interior uses of Kenyte include Decorative aggregates, Entryways, Homes, Interior decoration and Kitchens whereas the interior uses of Siltstone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Kenyte and Siltstone, they have various applications in construction industry. The uses of Kenyte in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics and that of Siltstone include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Kenyte and Siltstone
Here you can know more about Kenyte and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kenyte and Siltstone consists of mineral content and compound content.
