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
Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar

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.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

More about Shoshonite and Trachyte
Here you can know more about Shoshonite and Trachyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Trachyte consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Trachyte, 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, Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. Appearance of Shoshonite is Dull and that of Trachyte is Banded. Properties of rock is another aspect for Shoshonite vs Trachyte. Hardness of Shoshonite and Trachyte is 6. The types of Shoshonite are Not Available whereas types of Trachyte are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shoshonite is white to grey while that of Trachyte is white. The specific heat capacity of Shoshonite is Not Available and that of Trachyte 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 Trachyte is heat resistant, impact resistant, wear resistant.
