Definition
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment
  
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
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
  
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.

Hyaloclastite 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. Hyaloclastite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hyaloclastite and Properties of Mudstone. Learn more about Hyaloclastite vs Mudstone in the next section. The interior uses of Hyaloclastite include Countertops, Decorative aggregates, 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 Hyaloclastite and Mudstone, they have various applications in construction industry. The uses of Hyaloclastite in construction industry include Building houses or walls, Construction aggregate and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Hyaloclastite and Mudstone
Here you can know more about Hyaloclastite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Mudstone consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite 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 Hyaloclastite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Hyaloclastite is Dull and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Hyaloclastite vs Mudstone. The hardness of Hyaloclastite is 1-2 and that of Mudstone is 2-3. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. 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 Hyaloclastite is colorless while that of Mudstone is white. The specific heat capacity of Hyaloclastite 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.Hyaloclastite is heat resistant whereas Mudstone is heat resistant, impact resistant.
