Formation
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

Shale 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. Shale vs Jaspillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Jaspillite. Learn more about Shale vs Jaspillite in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Jaspillite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Shale and Jaspillite, they have various applications in construction industry. The uses of Shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar 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 Shale and Jaspillite
Here you can know more about Shale and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Jaspillite consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Jaspillite, the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Jaspillite is available in red, reddish brown colors. Appearance of Shale is Muddy and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Shale vs Jaspillite. Hardness of Shale and Jaspillite is 3. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale 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 Shale and Jaspillite is white. The specific heat capacity of Shale is 0.39 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.Shale is heat resistant, impact resistant whereas Jaspillite is heat resistant, impact resistant, wear resistant.
