Definition
Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar
  
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
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
  
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

More about Diabase and Hyaloclastite
Here you can know more about Diabase and Hyaloclastite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Hyaloclastite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine and mineral content of Hyaloclastite includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Diabase vs Hyaloclastite , the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Hyaloclastite is available in brown, grey, yellow colors. Appearance of Diabase is Vesicular and that of Hyaloclastite is Dull. Properties of rock is another aspect for Diabase vs Hyaloclastite . The hardness of Diabase is 7 and that of Hyaloclastite is 1-2. The types of Diabase are Not Available 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 Diabase is black while that of Hyaloclastite is colorless. The specific heat capacity of Diabase is Not Available and that of Hyaloclastite is Not Available.
