Definition
Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Anorthosite vs Conglomerate 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. Anorthosite vs Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anorthosite and Properties of Conglomerate. Learn more about Anorthosite vs Conglomerate in the next section. The interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Anorthosite and Conglomerate, they have various applications in construction industry. The uses of Anorthosite in construction industry include As dimension stone, Cement manufacture, For road aggregate and that of Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.
More about Anorthosite and Conglomerate
Here you can know more about Anorthosite and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anorthosite and Conglomerate consists of mineral content and compound content. The mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Anorthosite vs Conglomerate, 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, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Anorthosite is Layered, Banded, Veined and Shiny and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Anorthosite vs Conglomerate. The hardness of Anorthosite is 5-6 and that of Conglomerate is 2-3. The types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite whereas types of Conglomerate are Orthoconglomerate and Paraconglomerate. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anorthosite and Conglomerate is white. The specific heat capacity of Anorthosite is 0.84 kJ/Kg K and that of Conglomerate is 0.92 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 Conglomerate is heat resistant.
