Formation

Formation

Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

Adakite vs Trachyte 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 Adakite and Trachyte Reserves. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar. 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 Adakite vs Trachyte information and Adakite vs Trachyte characteristics in the upcoming sections.

Adakite vs Trachyte Characteristics

More about Adakite and Trachyte

Here you can know more about Adakite and Trachyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Trachyte consists of mineral content and compound content. The mineral content of Adakite includes Olivine, Plagioclase, Pyroxene and mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Adakite vs Trachyte, the texture, color and appearance plays an important role in determining the type of rock. Adakite is available in black, brown, light to dark grey colors whereas, Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. Appearance of Adakite is Dull and Soft and that of Trachyte is Banded. Properties of rock is another aspect for Adakite vs Trachyte. The hardness of Adakite is 3-4 and that of Trachyte is 6. The types of Adakite are Intermediate volcanic rock whereas types of Trachyte are Felsic volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Adakite is bluish black while that of Trachyte is white. The specific heat capacity of Adakite is 0.84 kJ/Kg K and that of Trachyte 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.Adakite is heat resistant, pressure resistant, wear resistant whereas Trachyte is heat resistant, impact resistant, wear resistant.
