Definition
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase
  
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
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
  
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

Amphibolite vs Hyaloclastite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Amphibolite vs Hyaloclastite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Hyaloclastite . Learn more about Amphibolite vs Hyaloclastite in the next section. The interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens whereas the interior uses of Hyaloclastite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Amphibolite and Hyaloclastite , they have various applications in construction industry. The uses of Amphibolite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Hyaloclastite include Building houses or walls, Construction aggregate.
More about Amphibolite and Hyaloclastite
Here you can know more about Amphibolite and Hyaloclastite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Hyaloclastite consists of mineral content and compound content. The mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite and mineral content of Hyaloclastite includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Amphibolite vs Hyaloclastite , the texture, color and appearance plays an important role in determining the type of rock. Amphibolite is available in black, brown, green, grey colors whereas, Hyaloclastite is available in brown, grey, yellow colors. Appearance of Amphibolite is Foliated and that of Hyaloclastite is Dull. Properties of rock is another aspect for Amphibolite vs Hyaloclastite . The hardness of Amphibolite is 6-7 and that of Hyaloclastite is 1-2. The types of Amphibolite are Hornblendite 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 Amphibolite is white to grey while that of Hyaloclastite is colorless. The specific heat capacity of Amphibolite is Not Available and that of Hyaloclastite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Hyaloclastite is heat resistant.
