Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
  
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

Andesite vs Jaspillite 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. Andesite vs Jaspillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Andesite and Properties of Jaspillite. Learn more about Andesite vs Jaspillite in the next section. The interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Jaspillite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Andesite and Jaspillite, they have various applications in construction industry. The uses of Andesite in construction industry include Cobblestones, Construction aggregate, For road aggregate and that of Jaspillite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Andesite and Jaspillite
Here you can know more about Andesite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Jaspillite 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 Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Jaspillite, 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, Jaspillite is available in red, reddish brown colors. Appearance of Andesite is Dull and Soft and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Andesite vs Jaspillite. The hardness of Andesite is 7 and that of Jaspillite is 3. The types of Andesite are Icelandite whereas types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Andesite and Jaspillite is white. The specific heat capacity of Andesite is 2.39 kJ/Kg K and that of Jaspillite is 3.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Andesite is heat resistant, pressure resistant, wear resistant whereas Jaspillite is heat resistant, impact resistant, wear resistant.
