Definition
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Phyllite and Limestone Properties
Know all about Phyllite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Phyllite belongs to Metamorphic Rocks while Limestone belongs to Sedimentary Rocks.Texture of Phyllite is Phyllitic Sheen, Slaty whereas that of Limestone is Clastic or Non-Clastic. Phyllite appears Crinkled or Wavy and Limestone appears Rough and Banded. The luster of Phyllite is phyllitic while that of Limestone is dull to pearly. Phyllite is available in black to grey, light 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 Phyllite are cemetery markers, commemorative tablets, creating artwork, writing slates 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.
