Formation

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.
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.

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