Definition
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals

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

All about Breccia and Syenite Properties
Know all about Breccia and Syenite properties here. All properties of rocks are important as they define the type of rock and its application. Breccia belongs to Sedimentary Rocks while Syenite belongs to Igneous Rocks.Texture of Breccia is Brecciated, Clastic whereas that of Syenite is Earthy. Breccia appears Layered, Banded, Veined and Shiny and Syenite appears Banded and Foilated. The luster of Breccia is dull to pearly while that of Syenite is subvitreous to dull. 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. The commercial uses of Breccia are creating artwork, gemstone, jewelry and that of Syenite are cemetery markers, creating artwork.
