Etymology
From late Middle English (denoting slag from molten metal), from Greek skōria refuse, from skōr dung
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Archaeological Significance
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.

More about Scoria and Turbidite
Here you can know more about Scoria and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Turbidite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Scoria is Glassy and Vesicular and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Scoria vs Turbidite. The hardness of Scoria is 5-6 and that of Turbidite is 3. The types of Scoria are Basaltic Scoria and Andesitic Scoria whereas types of Turbidite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Scoria is 0.84 kJ/Kg K and that of Turbidite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
