Definition
Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

More about Trachyte and Suevite
Here you can know more about Trachyte and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyte and Suevite consists of mineral content and compound content. The mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Trachyte vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors whereas, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Trachyte is Banded and that of Suevite is Banded. Properties of rock is another aspect for Trachyte vs Suevite. The hardness of Trachyte is 6 and that of Suevite is 5.5. The types of Trachyte are Not Available whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Trachyte is white while that of Suevite is light to dark brown. The specific heat capacity of Trachyte is Not Available and that of Suevite 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.Trachyte is heat resistant, impact resistant, wear resistant whereas Suevite is heat resistant.
