More About Scoria

Scoria is a type of Igneous Rocks. The color of rock is one of its important property. Scoria rock is available in black, brown, dark grey to black, red colors. It is Glassy and Vesicular in appearance. The Scoria mineral content includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. Its compound content includes Ca, NaCl. Let’s move on to the types of Scoria. Scoria rock does not have any types. Fossils are the remains of prehistoric plants or animals which are embedded in rock and preserved in petrified form. Fossils are found only in sedimentary rocks. As Scoria belongs to Igneous Rocks, fossils are not found in it.
