Formation

Rhyodacite 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.

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.

Rhyodacite vs Latite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Rhyodacite and Latite Reserves. Rhyodacite is an extrusive volcanic rock intermediate in composition between dacite and rhyolite. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Rhyodacite vs Latite information and Rhyodacite vs Latite characteristics in the upcoming sections.

More about Rhyodacite and Latite

Here you can know more about Rhyodacite and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyodacite and Latite consists of mineral content and compound content. The mineral content of Rhyodacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Rhyodacite vs Latite, the texture, color and appearance plays an important role in determining the type of rock. Rhyodacite is available in black to grey, dark greenish - grey colors whereas, Latite is available in black, brown, green, grey, pink, white colors. Appearance of Rhyodacite is Skeletal and that of Latite is Rough. Properties of rock is another aspect for Rhyodacite vs Latite. The hardness of Rhyodacite is 5.5-6 and that of Latite is 5-5.5. The types of Rhyodacite are Intermediate volcanic rock whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Rhyodacite is black while that of Latite is white. The specific heat capacity of Rhyodacite is 1.12 kJ/Kg K and that of Latite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Rhyodacite is heat resistant whereas Latite is heat resistant, pressure resistant.
