Formation
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

More about Jaspillite and Mylonite
Here you can know more about Jaspillite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jaspillite and Mylonite consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Sedimentary Rocks. When we have to compare Jaspillite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Mylonite is available in black to grey colors. Appearance of Jaspillite is Banded and Glassy and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Jaspillite vs Mylonite. The hardness of Jaspillite is 3 and that of Mylonite is 3-4. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type whereas types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jaspillite and Mylonite is white. The specific heat capacity of Jaspillite is 3.20 kJ/Kg K and that of Mylonite is 1.50 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Jaspillite is heat resistant, impact resistant, wear resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
