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

Formation
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.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Ganister include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Wehrlite and Ganister
Here you can know more about Wehrlite and Ganister. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Ganister consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Ganister, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Ganister is Rough. Properties of rock is another aspect for Wehrlite vs Ganister. The hardness of Wehrlite is 5.5-6 and that of Ganister is 6-7. The types of Wehrlite are Not Available whereas types of Ganister are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Ganister is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Ganister is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Ganister is heat resistant, impact resistant, pressure resistant.
