Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

More about Hyaloclastite and Tuff
Here you can know more about Hyaloclastite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Tuff consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Hyaloclastite is Dull and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Hyaloclastite vs Tuff. The hardness of Hyaloclastite is 1-2 and that of Tuff is 4-6. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite.. 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 Tuff is white. The specific heat capacity of Hyaloclastite is Not Available and that of Tuff is 0.20 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 Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
