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.
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

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.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Ganister vs Granulite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Ganister vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Ganister and Properties of Granulite. Learn more about Ganister vs Granulite in the next section. The interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Ganister and Granulite, they have various applications in construction industry. The uses of Ganister in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar and that of Granulite include As dimension stone, Building houses or walls.
More about Ganister and Granulite
Here you can know more about Ganister and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Granulite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Ganister is Rough and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Ganister vs Granulite. Hardness of Ganister and Granulite is 6-7. The types of Ganister are Siliceous rock whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister and Granulite is white. The specific heat capacity of Ganister is 0.92 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
