1 Definition
1.1 Definition
Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers
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.

5.1 Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

Chalk vs Ganister Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Chalk and Ganister Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. 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.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Chalk vs Ganister information and Chalk vs Ganister characteristics in the upcoming sections.

Chalk vs Ganister 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. Chalk vs Ganister characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Ganister. Learn more about Chalk vs Ganister in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration.

The uses of Chalk in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium 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 Chalk and Ganister

Here you can know more about Chalk and Ganister. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Ganister consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Ganister, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow 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 Chalk is Soft and that of Ganister is Rough. Properties of rock is another aspect for Chalk vs Ganister. The hardness of Chalk is 1 and that of Ganister is 6-7. The types of Chalk 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 Chalk and Ganister is white. The specific heat capacity of Chalk is 0.90 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.Chalk is heat resistant whereas Ganister is heat resistant, impact resistant, pressure resistant.
