Definition
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
  
Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt

Formation
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.
  
Epidosite 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.

More about Shoshonite and Epidosite
Here you can know more about Shoshonite and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Epidosite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Epidosite, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Epidosite is available in black, brown, light to dark grey colors. Appearance of Shoshonite is Dull and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Shoshonite vs Epidosite. Hardness of Shoshonite and Epidosite is 6. The types of Shoshonite are Not Available whereas types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shoshonite and Epidosite is white to grey. The specific heat capacity of Shoshonite is Not Available and that of Epidosite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shoshonite is heat resistant, pressure resistant whereas Epidosite is heat resistant, pressure resistant, wear resistant.
