Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt

Features
Clasts are smooth to touch, Is one of the oldest rock, Matrix variable
Available in Lots of Colors and Patterns, Easily splits into thin plates, Generally rough to touch, High silica content, Very fine grained rock
Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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.

Conglomerate vs Siltstone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Conglomerate vs Siltstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Siltstone. Learn more about Conglomerate vs Siltstone in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Siltstone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Conglomerate and Siltstone, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Siltstone include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Conglomerate and Siltstone
Here you can know more about Conglomerate and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Siltstone consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Siltstone, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Siltstone is available in brown, red, reddish brown colors. Appearance of Conglomerate is Shiny and Rounded and that of Siltstone is Rough. Properties of rock is another aspect for Conglomerate vs Siltstone. The hardness of Conglomerate is 2-3 and that of Siltstone is 6-7. The types of Conglomerate are Orthoconglomerate and Paraconglomerate whereas types of Siltstone are Siltstone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Siltstone is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Siltstone is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Siltstone is heat resistant, impact resistant, pressure resistant, water resistant.
