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

Archaeological Significance
Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

Hyaloclastite vs Anorthosite 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. Hyaloclastite vs Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hyaloclastite and Properties of Anorthosite. Learn more about Hyaloclastite vs Anorthosite in the next section. The interior uses of Hyaloclastite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Hyaloclastite and Anorthosite, they have various applications in construction industry. The uses of Hyaloclastite in construction industry include Building houses or walls, Construction aggregate and that of Anorthosite include As dimension stone, Cement manufacture, For road aggregate.
More about Hyaloclastite and Anorthosite
Here you can know more about Hyaloclastite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Anorthosite consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Anorthosite, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Hyaloclastite is Dull and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Hyaloclastite vs Anorthosite. The hardness of Hyaloclastite is 1-2 and that of Anorthosite is 5-6. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. 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 Anorthosite is white. The specific heat capacity of Hyaloclastite is 0.84 kJ/Kg K and that of Anorthosite 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 Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
