Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

More about Andesite and Wackestone
Here you can know more about Andesite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Wackestone consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon and mineral content of Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all . When we have to compare Andesite vs Wackestone, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Andesite is Dull and Soft and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Andesite vs Wackestone. The hardness of Andesite is 7 and that of Wackestone is 2-3. The types of Andesite are Icelandite whereas types of Wackestone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Andesite and Wackestone is white.
