Archaeological Significance
Formation
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.
Trachyandesite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Breccia and Trachyandesite
Here you can know more about Breccia and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Breccia and Trachyandesite consists of mineral content and compound content. The mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica and mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Breccia vs Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors whereas, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Breccia is Layered, Banded, Veined and Shiny and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Breccia vs Trachyandesite. The hardness of Breccia is 7 and that of Trachyandesite is 4-5. The types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia whereas types of Trachyandesite are Basaltic Trachyandesite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Breccia is white while that of Trachyandesite is light to dark brown. The specific heat capacity of Breccia is 0.84 kJ/Kg K and that of Trachyandesite 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.Breccia is heat resistant, impact resistant, pressure resistant, wear resistant whereas Trachyandesite is heat resistant, pressure resistant, wear resistant.
