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
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

More about Basaltic Trachyandesite and Ignimbrite
Here you can know more about Basaltic Trachyandesite and Ignimbrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basaltic Trachyandesite and Ignimbrite consists of mineral content and compound content. The mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene and mineral content of Ignimbrite includes Apatite, Biotite, Calcite, Chlorite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Basaltic Trachyandesite vs Ignimbrite, 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, Ignimbrite is available in beige, black, brown, grey, pink, white colors. Appearance of Basaltic Trachyandesite is Dull and Soft and that of Ignimbrite is Dull, Vesicular and Foilated. Properties of rock is another aspect for Basaltic Trachyandesite vs Ignimbrite. The hardness of Basaltic Trachyandesite is 6 and that of Ignimbrite is 4-6. 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 Ignimbrite are Not Available. 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 Ignimbrite is white. The specific heat capacity of Basaltic Trachyandesite is 0.84 kJ/Kg K and that of Ignimbrite is 0.20 kJ/Kg K.
