Definition
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

More about Basaltic Trachyandesite and Granodiorite
Here you can know more about Basaltic Trachyandesite and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basaltic Trachyandesite and Granodiorite consists of mineral content and compound content. The mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene and mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Basaltic Trachyandesite vs Granodiorite, the texture, color and appearance plays an important role in determining the type of rock. Basaltic Trachyandesite is available in black, brown, light to dark grey colors whereas, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Basaltic Trachyandesite is Dull and Soft and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Basaltic Trachyandesite vs Granodiorite. Hardness of Basaltic Trachyandesite and Granodiorite is 6. The types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Granodiorite are Granodiorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basaltic Trachyandesite is white to grey while that of Granodiorite is white. The specific heat capacity of Basaltic Trachyandesite is 0.84 kJ/Kg K and that of Granodiorite 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.Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant whereas Granodiorite is heat resistant, wear resistant.
