Definition
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

Features
Always found as volcanic pipes over deep continental crust, Host rock for Diamond, Is one of the oldest rock, Surfaces are often shiny
Available in Lots of Colors and Patterns, Smooth to touch, Very fine grained rock
Archaeological Significance
Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

Vogesite vs Mudstone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Vogesite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Vogesite and Properties of Mudstone. Learn more about Vogesite vs Mudstone in the next section. The interior uses of Vogesite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Vogesite and Mudstone, they have various applications in construction industry. The uses of Vogesite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Vogesite and Mudstone
Here you can know more about Vogesite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Vogesite and Mudstone consists of mineral content and compound content. The mineral content of Vogesite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Vogesite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Vogesite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Vogesite is Dull, Banded and Foilated and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Vogesite vs Mudstone. The hardness of Vogesite is 5-6 and that of Mudstone is 2-3. The types of Vogesite are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite whereas types of Mudstone are Marl, Shale and Argillite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Vogesite and Mudstone is white. The specific heat capacity of Vogesite is 0.84 kJ/Kg K and that of Mudstone is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Vogesite is heat resistant, impact resistant whereas Mudstone is heat resistant, impact resistant.
