Formation

Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Gritstone and Andesite

Here you can know more about Gritstone and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Andesite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Gritstone is Layered and Foliated and that of Andesite is Dull and Soft. Properties of rock is another aspect for Gritstone vs Andesite. The hardness of Gritstone is 6-7 and that of Andesite is 7. The types of Gritstone are Sedimentary rock whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gritstone and Andesite is white. The specific heat capacity of Gritstone is 0.92 kJ/Kg K and that of Andesite is 2.39 kJ/Kg K.
