Formation
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.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

More about Granophyre and Travertine
Here you can know more about Granophyre and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Travertine consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Granophyre vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Granophyre is available in black, grey, orange, pink, white colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Granophyre is Veined or Pebbled and that of Travertine is Fibrous. Properties of rock is another aspect for Granophyre vs Travertine. The hardness of Granophyre is 6-7 and that of Travertine is 3-4. The types of Granophyre are Intermediate intrusive rock whereas types of Travertine are Thermal Travertine and Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granophyre and Travertine is white. The specific heat capacity of Granophyre is 0.79 kJ/Kg K and that of Travertine is 1.09 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granophyre is heat resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
