Definition
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite
Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

Etymology
From granite + diorite
From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

Archaeological Significance
Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

Granodiorite vs Argillite 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. Granodiorite vs Argillite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Argillite. Learn more about Granodiorite vs Argillite in the next section. The interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads whereas the interior uses of Argillite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Granodiorite and Argillite, they have various applications in construction industry. The uses of Granodiorite in construction industry include As dimension stone and that of Argillite include Used for flooring, stair treads, borders and window sills..
More about Granodiorite and Argillite
Here you can know more about Granodiorite and Argillite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Argillite consists of mineral content and compound content. The mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Argillite includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Argillite, the texture, color and appearance plays an important role in determining the type of rock. Granodiorite is available in black, grey, orange, pink, white colors whereas, Argillite is available in dark grey to black, pink, red, white colors. Appearance of Granodiorite is Veined or Pebbled and that of Argillite is Rough and Dull. Properties of rock is another aspect for Granodiorite vs Argillite. The hardness of Granodiorite is 6 and that of Argillite is 2-3. The types of Granodiorite are Granodiorite whereas types of Argillite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite is white while that of Argillite is white to grey. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Argillite is 0.87 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granodiorite is heat resistant, wear resistant whereas Argillite is heat resistant, impact resistant.
