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.
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

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.
Wehrlite 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.

More about Ganister and Wehrlite
Here you can know more about Ganister and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Wehrlite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Wehrlite, 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, Wehrlite is available in dark greenish - grey, green colors. Appearance of Ganister is Rough and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Ganister vs Wehrlite. The hardness of Ganister is 6-7 and that of Wehrlite is 5.5-6. The types of Ganister are Siliceous rock whereas types of Wehrlite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister and Wehrlite is white. The specific heat capacity of Ganister is 0.92 kJ/Kg K and that of Wehrlite is 0.63 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 Wehrlite is heat resistant, impact resistant, pressure resistant.
