Definition
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles
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

Formation
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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Shale and Marble Properties
Know all about Shale and Marble properties here. All properties of rocks are important as they define the type of rock and its application. Shale belongs to Sedimentary Rocks while Marble belongs to Metamorphic Rocks.Texture of Shale is Clastic, Splintery whereas that of Marble is Granular. Shale appears Muddy and Marble appears Veined and Shiny. The luster of Shale is dull while that of Marble is dull to pearly to subvitreous. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas Marble is available in black, blue, brown, grey, pink, white colors. The commercial uses of Shale are creating artwork, pottery and that 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.
