Formation
Hornblendite 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.
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.

More about Hornblendite and Trachyte
Here you can know more about Hornblendite and Trachyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Trachyte consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite 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 Hornblendite vs Trachyte, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. Appearance of Hornblendite is Foliated and that of Trachyte is Banded. Properties of rock is another aspect for Hornblendite vs Trachyte. The hardness of Hornblendite is 6-7 and that of Trachyte is 6. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Trachyte are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornblendite is white to grey while that of Trachyte is white. The specific heat capacity of Hornblendite is Not Available and that of Trachyte is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Trachyte is heat resistant, impact resistant, wear resistant.
