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.
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.

More about Granodiorite and Breccia
Here you can know more about Granodiorite and Breccia. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Breccia 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 Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Breccia, 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, Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors. Appearance of Granodiorite is Veined or Pebbled and that of Breccia is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Granodiorite vs Breccia. The hardness of Granodiorite is 6 and that of Breccia is 7. The types of Granodiorite are Granodiorite whereas types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite and Breccia is white. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Breccia is 0.84 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 Breccia is heat resistant, impact resistant, pressure resistant, wear resistant.
