Definition
Anorthosite is a granular igneous rock composed largely of labradorite or 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

Archaeological Significance
Formation
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 is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

More about Anorthosite and Hyaloclastite
Here you can know more about Anorthosite and Hyaloclastite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Hyaloclastite consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Hyaloclastite includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Hyaloclastite , the texture, color and appearance plays an important role in determining the type of rock. Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors whereas, Hyaloclastite is available in brown, grey, yellow colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Hyaloclastite is Dull. Properties of rock is another aspect for Anorthosite vs Hyaloclastite . The hardness of Anorthosite is 5-6 and that of Hyaloclastite is 1-2. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite 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 Anorthosite is white while that of Hyaloclastite is . The specific heat capacity of Anorthosite is 0.84 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.Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant whereas Hyaloclastite is heat resistant.
