Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
  
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 Eclogite and Jaspillite
Here you can know more about Eclogite and Jaspillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Jaspillite consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite 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 Eclogite vs Jaspillite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Jaspillite is available in red, reddish brown colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Jaspillite is Banded and Glassy. Properties of rock is another aspect for Eclogite vs Jaspillite. The hardness of Eclogite is 3.5-4 and that of Jaspillite is 3. The types of Eclogite are Not Available 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 Eclogite and Jaspillite is white. The specific heat capacity of Eclogite is Not Available 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.Eclogite is heat resistant whereas Jaspillite is heat resistant, impact resistant, wear resistant.
