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.
Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.

More about Granodiorite and Taconite
Here you can know more about Granodiorite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Taconite 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 Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Taconite, 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, Taconite is available in red, reddish brown colors. Appearance of Granodiorite is Veined or Pebbled and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Granodiorite vs Taconite. The hardness of Granodiorite is 6 and that of Taconite is 5.5-6. The types of Granodiorite are Granodiorite whereas types of Taconite are Iron formation. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite and Taconite is white. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Taconite is 3.20 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 Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
