Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Hornblendite 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.

More about Limestone and Hornblendite
Here you can know more about Limestone and Hornblendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Hornblendite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite. You can also check out the list of all . When we have to compare Limestone vs Hornblendite, 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, Hornblendite is available in black, brown, green, grey colors. Appearance of Limestone is Rough and Banded and that of Hornblendite is Foliated. Properties of rock is another aspect for Limestone vs Hornblendite. The hardness of Limestone is 3-4 and that of Hornblendite is 6-7. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone is white while that of Hornblendite is white to grey. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Hornblendite is Not Available. 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 Hornblendite is heat resistant, pressure resistant, wear resistant.
