Definition
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

Granodiorite vs Soapstone 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. Granodiorite vs Soapstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granodiorite and Properties of Soapstone. Learn more about Granodiorite vs Soapstone in the next section. The interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads whereas the interior uses of Soapstone include Bathrooms, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Granodiorite and Soapstone, they have various applications in construction industry. The uses of Granodiorite in construction industry include As dimension stone and that of Soapstone include Manufacture of magnesium and dolomite refractories.
More about Granodiorite and Soapstone
Here you can know more about Granodiorite and Soapstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Soapstone consists of mineral content and compound content. The mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Granodiorite vs Soapstone, the texture, color and appearance plays an important role in determining the type of rock. Granodiorite is available in black, grey, orange, pink, white colors whereas, Soapstone is available in black, black to grey, green, grey colors. Appearance of Granodiorite is Veined or Pebbled and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Granodiorite vs Soapstone. The hardness of Granodiorite is 6 and that of Soapstone is 1. The types of Granodiorite are Not Available whereas types of Soapstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granodiorite is white while that of Soapstone is black. The specific heat capacity of Granodiorite is 0.79 kJ/Kg K and that of Soapstone is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granodiorite is heat resistant, wear resistant whereas Soapstone is heat resistant, pressure resistant.
