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
Aplite is a fine-grained granite composed mainly of feldspar and quartz

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

More about Hyaloclastite and Aplite
Here you can know more about Hyaloclastite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Aplite consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Hyaloclastite is Dull and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Hyaloclastite vs Aplite. The hardness of Hyaloclastite is 1-2 and that of Aplite is 6.5. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Aplite are Not Available. 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 Aplite is white. The specific heat capacity of Hyaloclastite is Not Available and that of Aplite is 0.79 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 Aplite is heat resistant, wear resistant.
