Definition
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.
Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks

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.
Gneiss is a high grade metamorphic rock i.e. it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of Gneiss forms from volcanic rock, shale or granitie.

Wackestone vs Gneiss 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 Gneiss characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wackestone and Properties of Gneiss. Learn more about Wackestone vs Gneiss in the next section. The interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Wackestone and Gneiss, they have various applications in construction industry.

You can also check out the list of all Sedimentary Rocks. When we have to compare Wackestone vs Gneiss, 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, Gneiss is available in black, brown, pink, red, white colors. Appearance of Wackestone is Rough and Dull and that of Gneiss is Foliated. Properties of rock is another aspect for Wackestone vs Gneiss. The hardness of Wackestone is 2-3 and that of Gneiss is 7. The types of Wackestone are Marl, Shale and Argillite whereas types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wackestone and Gneiss is white. The specific heat capacity of Wackestone is 0.39 kJ/Kg K and that of Gneiss is Not Available. 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 Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant.
