Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass

Formation
Tachylite 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.
Granophyre 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.

More about Tachylite and Granophyre
Here you can know more about Tachylite and Granophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tachylite and Granophyre consists of mineral content and compound content. The mineral content of Tachylite includes Feldspar, Olivine and mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tachylite vs Granophyre, the texture, color and appearance plays an important role in determining the type of rock. Tachylite is available in black, dark brown colors whereas, Granophyre is available in black, grey, orange, pink, white colors. Appearance of Tachylite is Glassy and that of Granophyre is Veined or Pebbled. Properties of rock is another aspect for Tachylite vs Granophyre. The hardness of Tachylite is 5.5 and that of Granophyre is 6-7. The types of Tachylite are Not Available whereas types of Granophyre are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tachylite is vermilion while that of Granophyre is white. The specific heat capacity of Tachylite is 0.56 kJ/Kg K and that of Granophyre is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tachylite is heat resistant, impact resistant, wear resistant whereas Granophyre is heat resistant, wear resistant.
