Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
  
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

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
  
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.

Hawaiite 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. Hawaiite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hawaiite and Properties of Mudstone. Learn more about Hawaiite vs Mudstone in the next section. The interior uses of Hawaiite include Decorative aggregates, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Hawaiite and Mudstone, they have various applications in construction industry. The uses of Hawaiite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Hawaiite and Mudstone
Here you can know more about Hawaiite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Mudstone consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, 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 Hawaiite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Hawaiite is available in black, brown, light to dark grey colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Hawaiite is Dull and Soft and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Hawaiite vs Mudstone. The hardness of Hawaiite is 6 and that of Mudstone is 2-3. The types of Hawaiite are Not Available 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 Hawaiite is not available while that of Mudstone is white. The specific heat capacity of Hawaiite is Not Available 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.Hawaiite is heat resistant, pressure resistant, wear resistant whereas Mudstone is heat resistant, impact resistant.
