Definition
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

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.
Shoshonite 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.

All about Breccia and Shoshonite Properties
Know all about Breccia and Shoshonite properties here. All properties of rocks are important as they define the type of rock and its application. Breccia belongs to Sedimentary Rocks while Shoshonite belongs to Igneous Rocks.Texture of Breccia is Brecciated, Clastic whereas that of Shoshonite is Porphyritic. Breccia appears Layered, Banded, Veined and Shiny and Shoshonite appears Dull. The luster of Breccia is dull to pearly while that of Shoshonite is dull. Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors whereas Shoshonite is available in brown- black, dark brown colors. The commercial uses of Breccia are creating artwork, gemstone, jewelry and that of Shoshonite are cemetery markers, creating artwork.
