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.

Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

More about Gritstone and Rhyolite

Here you can know more about Gritstone and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Rhyolite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Rhyolite, 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, Rhyolite is available in grey, white, light black colors. Appearance of Gritstone is Layered and Foliated and that of Rhyolite is Banded. Properties of rock is another aspect for Gritstone vs Rhyolite. Hardness of Gritstone and Rhyolite is 6-7. The types of Gritstone are Sedimentary rock whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gritstone is white while that of Rhyolite is . The specific heat capacity of Gritstone is 0.92 kJ/Kg K and that of Rhyolite is 0.71 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Gritstone is heat resistant, impact resistant, pressure resistant whereas Rhyolite is heat resistant, wear resistant.
