Definition
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

Archaeological Significance
Formation
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.
Tachylite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Wackestone vs Tachylite 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. Wackestone vs Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wackestone and Properties of Tachylite. Learn more about Wackestone vs Tachylite in the next section. The interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Wackestone and Tachylite, they have various applications in construction industry. The uses of Wackestone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Tachylite include Cutting tool, Knives, Landscaping, Scrapers.
More about Wackestone and Tachylite
Here you can know more about Wackestone and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wackestone and Tachylite consists of mineral content and compound content. The mineral content of Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Sedimentary Rocks. When we have to compare Wackestone vs Tachylite, the texture, color and appearance plays an important role in determining the type of rock. Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Tachylite is available in black, dark brown colors. Appearance of Wackestone is Rough and Dull and that of Tachylite is Glassy. Properties of rock is another aspect for Wackestone vs Tachylite. The hardness of Wackestone is 2-3 and that of Tachylite is 5.5. The types of Wackestone are Marl, Shale and Argillite whereas types of Tachylite are Volcanic glass. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wackestone is white while that of Tachylite is vermilion. The specific heat capacity of Wackestone is 0.39 kJ/Kg K and that of Tachylite is 0.56 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Wackestone is heat resistant, impact resistant whereas Tachylite is heat resistant, impact resistant, wear resistant.
