Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar

Available in Lots of Colors and Patterns, Smooth to touch, Very fine grained rock
Always found as volcanic pipes over deep continental crust, Host rock for Diamond, Is one of the oldest rock, Surfaces are often shiny
Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

More about Claystone and Vogesite
Here you can know more about Claystone and Vogesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Vogesite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Vogesite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Claystone is Rough and Dull and that of Vogesite is Dull, Banded and Foilated. Properties of rock is another aspect for Claystone vs Vogesite. The hardness of Claystone is 3.5-4 and that of Vogesite is 5-6. The types of Claystone are Claystone whereas types of Vogesite are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Vogesite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Vogesite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Vogesite is heat resistant, impact resistant.
