Archaeological Significance
Formation
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.
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 Pumice and Turbidite
Here you can know more about Pumice and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Turbidite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, 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 Pumice vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Pumice is Vesicular and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Pumice vs Turbidite. The hardness of Pumice is 6 and that of Turbidite is 3. The types of Pumice are 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 Pumice and Turbidite is white, greenish white or grey. The specific heat capacity of Pumice is 0.87 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.Pumice is impact resistant, pressure resistant whereas Turbidite is heat resistant.
