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.
  
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

More about Hornblendite and Quartzite
Here you can know more about Hornblendite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Quartzite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Hornblendite is Foliated and that of Quartzite is Lustrous. Properties of rock is another aspect for Hornblendite vs Quartzite. Hardness of Hornblendite and Quartzite is 6-7. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Quartzite 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 Quartzite is white. The specific heat capacity of Hornblendite is Not Available and that of Quartzite is 0.75 kJ/Kg K. 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
