Definition
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene

Archaeological Significance
Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
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 Ganister and Diorite
Here you can know more about Ganister and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Diorite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz 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 Sedimentary Rocks. When we have to compare Ganister vs Diorite, the texture, color and appearance plays an important role in determining the type of rock. Ganister is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Ganister is Rough and that of Diorite is Shiny. Properties of rock is another aspect for Ganister vs Diorite. Hardness of Ganister and Diorite is 6-7. The types of Ganister are Siliceous rock whereas types of Diorite are Plagioclase Diorite and Quartz Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister is white while that of Diorite is bluish black. The specific heat capacity of Ganister is 0.92 kJ/Kg K and that of Diorite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Ganister is heat resistant, impact resistant, pressure resistant whereas Diorite is heat resistant, pressure resistant, wear resistant.
