5.1 Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

More about Skarn and Jaspillite

Here you can know more about Skarn and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Jaspillite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Jaspillite includes Coesite, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Jaspillite, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, colourless, green, grey, white colors whereas, Jaspillite is available in red, reddish brown colors. Appearance of Skarn is Dull and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Skarn vs Jaspillite. The hardness of Skarn is 6.5 and that of Jaspillite is 3. The types of Skarn are Endoskarns 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 Skarn is light to dark brown while that of Jaspillite is white.
