Formation

Formation

Hornblendite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

You can also check out the list of all Igneous Rocks. When we have to compare Hornblendite vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Hornblendite is Foliated and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Hornblendite vs Eclogite. The hardness of Hornblendite is 6-7 and that of Eclogite is 3.5-4. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite whereas types of Eclogite are Eclogite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hornblendite is white to grey while that of Eclogite is white. The specific heat capacity of Hornblendite is 0.84 kJ/Kg K and that of Eclogite is 0.75 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Eclogite is heat resistant.
