Definition
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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

All about Pyrolite and Limestone Properties
Know all about Pyrolite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Pyrolite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Pyrolite is Phaneritic whereas that of Limestone is Clastic or Non-Clastic. Pyrolite appears Rough and Shiny and Limestone appears Rough and Banded. The luster of Pyrolite is shiny while that of Limestone is dull to pearly. Pyrolite is available in dark greenish - grey 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. The commercial uses of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
