Definition
Essexite which is also known as nepheline monzogabbro, is a dark gray or black holocrystalline plutonic Iigneous Rock
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation
Essexite is a type of igneous rock, which is usually dark grey to black plutonic rock. For the formation of essexite, suitable magma with exact composition of K, Ba, Rb, Cs, Sr should be produced.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

More about Essexite and Limestone
Here you can know more about Essexite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Essexite and Limestone consists of mineral content and compound content. The mineral content of Essexite includes Augite, Feldspar, Hornblende, Nepheline, Olivine, Plagioclase, Pyroxene and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Essexite vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Essexite is available in dark grey to black colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Essexite is Banded and that of Limestone is Rough and Banded. Properties of rock is another aspect for Essexite vs Limestone. The hardness of Essexite is 7 and that of Limestone is 3-4. The types of Essexite are Not Available whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Essexite is black while that of Limestone is white. The specific heat capacity of Essexite is Not Available and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Essexite is impact resistant, pressure resistant, wear resistant whereas Limestone is pressure resistant.
