Archaeological Significance
Formation
Latite 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.

Latite 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. Latite vs Siltstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Latite and Properties of Siltstone. Learn more about Latite vs Siltstone in the next section. The interior uses of Latite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Siltstone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Latite and Siltstone, they have various applications in construction industry. The uses of Latite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories 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 Latite and Siltstone
Here you can know more about Latite and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Siltstone consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene 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 Latite vs Siltstone, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, green, grey, pink, white colors whereas, Siltstone is available in brown, red, reddish brown colors. Appearance of Latite is Rough and that of Siltstone is Rough. Properties of rock is another aspect for Latite vs Siltstone. The hardness of Latite is 5-5.5 and that of Siltstone is 6-7. The types of Latite are Rhomb porphyries whereas types of Siltstone are Siltstone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite and Siltstone is white. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Siltstone is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Latite is heat resistant, pressure resistant whereas Siltstone is heat resistant, impact resistant, pressure resistant, water resistant.
