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.
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Latite vs Rhyolite 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 Rhyolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Latite and Properties of Rhyolite. Learn more about Latite vs Rhyolite in the next section. The interior uses of Latite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Rhyolite include Decorative aggregates, Homes, Hotels, Interior decoration and Kitchens. Due to some exceptional properties of Latite and Rhyolite, 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 Rhyolite include Arrowheads, As dimension stone, Building houses or walls, Construction aggregate, Cutting tool, For road aggregate, Knives.
More about Latite and Rhyolite
Here you can know more about Latite and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Latite and Rhyolite consists of mineral content and compound content. The mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Latite vs Rhyolite, the texture, color and appearance plays an important role in determining the type of rock. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas, Rhyolite is available in grey, white, light black colors. Appearance of Latite is Rough and that of Rhyolite is Banded. Properties of rock is another aspect for Latite vs Rhyolite. The hardness of Latite is 5-5.5 and that of Rhyolite is 6-7. The types of Latite are Rhomb porphyries whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Latite is white while that of Rhyolite is colorless. The specific heat capacity of Latite is 0.92 kJ/Kg K and that of Rhyolite is Not Available. 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 Rhyolite is heat resistant, wear resistant.
