Archaeological Significance
Formation
Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.
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 Gritstone and Breccia
Here you can know more about Gritstone and Breccia. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Breccia consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Breccia, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors. Appearance of Gritstone is Layered and Foliated and that of Breccia is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Gritstone vs Breccia. The hardness of Gritstone is 6-7 and that of Breccia is 7. The types of Gritstone are Sedimentary rock 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 Gritstone and Breccia is white. The specific heat capacity of Gritstone is 0.92 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.Gritstone is heat resistant, impact resistant, pressure resistant whereas Breccia is heat resistant, impact resistant, pressure resistant, wear resistant.
