Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite

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.
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

More about Eclogite and Hawaiite
Here you can know more about Eclogite and Hawaiite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Hawaiite 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 Hawaiite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Hawaiite, 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, Hawaiite is available in black, brown, light to dark grey colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Hawaiite is Dull and Soft. Properties of rock is another aspect for Eclogite vs Hawaiite. The hardness of Eclogite is 3.5-4 and that of Hawaiite is 6. The types of Eclogite are Eclogite whereas types of Hawaiite are Volcanic rock. 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 Hawaiite is .
