Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.   
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Chalk vs Granodiorite 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 Granodiorite Reserves. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite. 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 Granodiorite information and Chalk vs Granodiorite characteristics in the upcoming sections.

Chalk vs Granodiorite 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 Granodiorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Chalk and Properties of Granodiorite. Learn more about Chalk vs Granodiorite in the next section. The interior uses of Chalk include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads. Due to some exceptional properties of Chalk and Granodiorite, they have various applications in construction industry. 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 Granodiorite include As dimension stone.

More about Chalk and Granodiorite

Here you can know more about Chalk and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Granodiorite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Granodiorite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Chalk is Soft and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Chalk vs Granodiorite. The hardness of Chalk is 1 and that of Granodiorite is 6. The types of Chalk are Not Available whereas types of Granodiorite 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 Granodiorite is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Granodiorite 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.Chalk is heat resistant whereas Granodiorite is heat resistant, wear resistant.
