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
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene

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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

More about Shoshonite and Diorite
Here you can know more about Shoshonite and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Diorite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Diorite, 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, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Shoshonite is Dull and that of Diorite is Shiny. Properties of rock is another aspect for Shoshonite vs Diorite. The hardness of Shoshonite is 6 and that of Diorite is 6-7. The types of Shoshonite are Not Available whereas types of Diorite 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 Diorite is bluish black. The specific heat capacity of Shoshonite is Not Available and that of Diorite is Not Available.
