Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals

Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Conglomerate vs Syenite 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. Conglomerate vs Syenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Syenite. Learn more about Conglomerate vs Syenite in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration. Due to some exceptional properties of Conglomerate and Syenite, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Syenite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Conglomerate and Syenite
Here you can know more about Conglomerate and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Syenite consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Syenite, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Conglomerate is Shiny and Rounded and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Conglomerate vs Syenite. The hardness of Conglomerate is 2-3 and that of Syenite is 5.5-6. The types of Conglomerate are Orthoconglomerate and Paraconglomerate whereas types of Syenite are Shonkinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Syenite is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Syenite 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.Conglomerate is heat resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
