Gabbro vs Slate 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 Gabbro and Slate Reserves. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. 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 Gabbro vs Slate information and Gabbro vs Slate characteristics in the upcoming sections.
