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
  
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
  
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Hyaloclastite vs Shale 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 Shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hyaloclastite and Properties of Shale. Learn more about Hyaloclastite vs Shale in the next section. The interior uses of Hyaloclastite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Shale include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Hyaloclastite and Shale, they have various applications in construction industry. The uses of Hyaloclastite in construction industry include Building houses or walls, Construction aggregate and that of Shale include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Hyaloclastite and Shale
Here you can know more about Hyaloclastite and Shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Shale consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Shale, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Hyaloclastite is Dull and that of Shale is Muddy. Properties of rock is another aspect for Hyaloclastite vs Shale. The hardness of Hyaloclastite is 1-2 and that of Shale is 3. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale. 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 Shale is white. The specific heat capacity of Hyaloclastite is Not Available and that of Shale 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 Shale is heat resistant, impact resistant.
