Definition
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt
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
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Siltstone and Marble
Here you can know more about Siltstone and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Siltstone and Marble consists of mineral content and compound content. The mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Siltstone vs Marble, the texture, color and appearance plays an important role in determining the type of rock. Siltstone is available in brown, red, reddish brown colors whereas, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Siltstone is Rough and that of Marble is Veined and Shiny. Properties of rock is another aspect for Siltstone vs Marble. The hardness of Siltstone is 6-7 and that of Marble is 3-4. The types of Siltstone are Not Available whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Siltstone and Marble is white. The specific heat capacity of Siltstone is Not Available and that of Marble is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Siltstone is heat resistant, impact resistant, pressure resistant, water resistant whereas Marble is heat resistant.
