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.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

More about Hornblendite and Phyllite
Here you can know more about Hornblendite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Phyllite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Hornblendite is Foliated and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Hornblendite vs Phyllite. The hardness of Hornblendite is 6-7 and that of Phyllite is 1-2. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Phyllite 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 Phyllite is white. The specific heat capacity of Hornblendite is Not Available and that of Phyllite 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 Phyllite is heat resistant, pressure resistant, water resistant.
