Definition
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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

Pyrolite 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. Pyrolite vs Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyrolite and Properties of Conglomerate. Learn more about Pyrolite vs Conglomerate in the next section. The interior uses of Pyrolite include Decorative aggregates and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Pyrolite and Conglomerate, they have various applications in construction industry. The uses of Pyrolite in construction industry include As dimension stone, Cobblestones and that of Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.
More about Pyrolite and Conglomerate
Here you can know more about Pyrolite and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Conglomerate consists of mineral content and compound content. The mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene 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 Pyrolite vs Conglomerate, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Pyrolite is Rough and Shiny and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Pyrolite vs Conglomerate. The hardness of Pyrolite is 5.5-6 and that of Conglomerate is 2-3. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite 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 Pyrolite and Conglomerate is white. The specific heat capacity of Pyrolite is 1.25 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.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Conglomerate is heat resistant.
