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
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite

Archaeological Significance
Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Ijolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Hyaloclastite and Ijolite
Here you can know more about Hyaloclastite and Ijolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Ijolite consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Ijolite, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Ijolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Hyaloclastite is Dull and that of Ijolite is Banded and Foilated. Properties of rock is another aspect for Hyaloclastite vs Ijolite. The hardness of Hyaloclastite is 1-2 and that of Ijolite is 5.5-6. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Ijolite are Alkaline rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hyaloclastite is while that of Ijolite is white. The specific heat capacity of Hyaloclastite is 0.84 kJ/Kg K and that of Ijolite is 0.84 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 Ijolite is heat resistant, impact resistant, wear resistant.
