Definition
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
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

Archaeological Significance
Formation
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.
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 Adakite and Breccia
Here you can know more about Adakite and Breccia. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Adakite and Breccia consists of mineral content and compound content. The mineral content of Adakite includes Olivine, Plagioclase, Pyroxene 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 Adakite vs Breccia, the texture, color and appearance plays an important role in determining the type of rock. Adakite is available in black, brown, light to dark grey colors whereas, Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors. Appearance of Adakite is Dull and Soft and that of Breccia is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Adakite vs Breccia. The hardness of Adakite is 3-4 and that of Breccia is 7. The types of Adakite are Intermediate volcanic 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 Adakite is bluish black while that of Breccia is white. The specific heat capacity of Adakite is 0.84 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.Adakite is heat resistant, pressure resistant, wear resistant whereas Breccia is heat resistant, impact resistant, pressure resistant, wear resistant.
