Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Scoria and Turbidite Properties
Know all about Scoria and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Scoria belongs to Igneous Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Scoria is Vesicular whereas that of Turbidite is Mud-rich, Sandy. Scoria appears Glassy and Vesicular and Turbidite appears Dull and Banded. The luster of Scoria is subvitreous to dull while that of Turbidite is metallic. Scoria is available in black, brown, dark grey to black, red colors whereas Turbidite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills and that of Turbidite are cemetery markers, creating artwork.
