Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

Basanite 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. Basanite vs Siltstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Siltstone. Learn more about Basanite vs Siltstone in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Siltstone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Basanite and Siltstone, they have various applications in construction industry. The uses of Basanite in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points 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 Basanite and Siltstone
Here you can know more about Basanite and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Siltstone consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Siltstone, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Siltstone is available in brown, red, reddish brown colors. Appearance of Basanite is Glassy or Pearly and that of Siltstone is Rough. Properties of rock is another aspect for Basanite vs Siltstone. The hardness of Basanite is 7 and that of Siltstone is 6-7. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Siltstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite and Siltstone is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Siltstone is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Siltstone is heat resistant, impact resistant, pressure resistant, water resistant.
