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.
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

Features
Available in Lots of Colors and Patterns, Generally rough to touch, Very fine grained rock
Easily splits into thin plates, Is one of the oldest rock, Surfaces are often shiny
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.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

More about Ganister and Phyllite
Here you can know more about Ganister and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Phyllite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Ganister is Rough and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Ganister vs Phyllite. The hardness of Ganister is 6-7 and that of Phyllite is 1-2. The types of Ganister are Siliceous rock whereas types of Phyllite are Phyllite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister and Phyllite is white. The specific heat capacity of Ganister is 0.92 kJ/Kg K and that of Phyllite is 0.79 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 Phyllite is heat resistant, pressure resistant, water resistant.
