5 Formation

5.1 Formation

Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

Ignimbrite vs Eclogite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Ignimbrite and Eclogite Reserves. Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Ignimbrite vs Eclogite information and Ignimbrite vs Eclogite characteristics in the upcoming sections.
