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
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Norite 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 Basaltic Trachyandesite and Norite
Here you can know more about Basaltic Trachyandesite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basaltic Trachyandesite and Norite consists of mineral content and compound content. The mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Basaltic Trachyandesite vs Norite, 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, Norite is available in dark grey to black colors. Appearance of Basaltic Trachyandesite is Dull and Soft and that of Norite is Veined and Shiny. Properties of rock is another aspect for Basaltic Trachyandesite vs Norite. The hardness of Basaltic Trachyandesite is 6 and that of Norite is 7. 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 Norite are Ultramafic intrusive rock. 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 Norite is black.
