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.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Breccia and Syenite
Here you can know more about Breccia and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Breccia and Syenite consists of mineral content and compound content. The mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica and mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Breccia vs Syenite, 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, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Breccia is Layered, Banded, Veined and Shiny and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Breccia vs Syenite. The hardness of Breccia is 7 and that of Syenite is 5.5-6. The types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia whereas types of Syenite are Shonkinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Breccia and Syenite is white. The specific heat capacity of Breccia is Not Available and that of Syenite is 0.92 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 Syenite is heat resistant, impact resistant, wear resistant.
