Definition
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

More about Breccia and Adakite
Here you can know more about Breccia and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Breccia and Adakite consists of mineral content and compound content. The mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Breccia vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Breccia is Layered, Banded, Veined and Shiny and that of Adakite is Dull and Soft. Properties of rock is another aspect for Breccia vs Adakite. The hardness of Breccia is 7 and that of Adakite is 3-4. The types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia whereas types of Adakite are Intermediate volcanic rock. 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 Adakite is bluish black. The specific heat capacity of Breccia is 0.84 kJ/Kg K and that of Adakite 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 Adakite is heat resistant, pressure resistant, wear resistant.
