Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Alkali fledspar granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Limestone vs Alkali Feldspar Granite 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. Limestone vs Alkali Feldspar Granite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Alkali Feldspar Granite. Learn more about Limestone vs Alkali Feldspar Granite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Alkali Feldspar Granite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Limestone and Alkali Feldspar Granite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Alkali Feldspar Granite include As dimension stone.
More about Limestone and Alkali Feldspar Granite
Here you can know more about Limestone and Alkali Feldspar Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Alkali Feldspar Granite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Alkali Feldspar Granite 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 Limestone vs Alkali Feldspar Granite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Alkali Feldspar Granite is available in black, grey, orange, pink, white colors. Appearance of Limestone is Rough and Banded and that of Alkali Feldspar Granite is Veined or Pebbled. Properties of rock is another aspect for Limestone vs Alkali Feldspar Granite. The hardness of Limestone is 3-4 and that of Alkali Feldspar Granite is 6-7. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Alkali Feldspar Granite are Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone and Alkali Feldspar Granite is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Alkali Feldspar Granite 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.Limestone is pressure resistant whereas Alkali Feldspar Granite is heat resistant, wear resistant.
