Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
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
Foidolites 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.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

More about Foidolite and Hyaloclastite
Here you can know more about Foidolite and Hyaloclastite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Hyaloclastite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Hyaloclastite includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Foidolite vs Hyaloclastite , the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, green, grey, pink, white colors whereas, Hyaloclastite is available in brown, grey, yellow colors. Appearance of Foidolite is Dull and that of Hyaloclastite is Dull. Properties of rock is another aspect for Foidolite vs Hyaloclastite . The hardness of Foidolite is 1.5 and that of Hyaloclastite is 1-2. The types of Foidolite are Igneous rock 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 Foidolite is white while that of Hyaloclastite is . The specific heat capacity of Foidolite is 0.79 kJ/Kg K and that of Hyaloclastite 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.Foidolite is heat resistant, wear resistant whereas Hyaloclastite is heat resistant.
