Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

Formation
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 is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

More about Shale and Hyaloclastite
Here you can know more about Shale and Hyaloclastite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Hyaloclastite consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Hyaloclastite includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Hyaloclastite , the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Hyaloclastite is available in brown, grey, yellow colors. Appearance of Shale is Muddy and that of Hyaloclastite is Dull. Properties of rock is another aspect for Shale vs Hyaloclastite . The hardness of Shale is 3 and that of Hyaloclastite is 1-2. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shale is white while that of Hyaloclastite is .
