Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

Basanite vs Gritstone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Basanite vs Gritstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Gritstone. Learn more about Basanite vs Gritstone in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Basanite and Gritstone, they have various applications in construction industry. The uses of Basanite in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Gritstone include Construction aggregate, Roadstone.
More about Basanite and Gritstone
Here you can know more about Basanite and Gritstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Gritstone consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase and mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Basanite vs Gritstone, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Basanite is Glassy or Pearly and that of Gritstone is Layered and Foliated. Properties of rock is another aspect for Basanite vs Gritstone. The hardness of Basanite is 7 and that of Gritstone is 6-7. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite whereas types of Gritstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basanite and Gritstone is white. The specific heat capacity of Basanite is 0.74 kJ/Kg K and that of Gritstone is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Gritstone is heat resistant, impact resistant, pressure resistant.
