Definition
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

All about Marble and Shale Properties
Know all about Marble and Shale properties here. All properties of rocks are important as they define the type of rock and its application. Marble belongs to Metamorphic Rocks while Shale belongs to Sedimentary Rocks.Texture of Marble is Granular whereas that of Shale is Clastic, Splintery. Marble appears Veined and Shiny and Shale appears Muddy. The luster of Marble is dull to pearly to subvitreous while that of Shale is dull. Marble is available in black, blue, brown, grey, pink, white colors whereas Shale is available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper and that of Shale are creating artwork, pottery.
