Formation
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
  
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.

Breccia 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. Breccia vs Siltstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Breccia and Properties of Siltstone. Learn more about Breccia vs Siltstone in the next section. The interior uses of Breccia include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Siltstone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Breccia and Siltstone, they have various applications in construction industry. The uses of Breccia in construction industry include As dimension stone, Construction aggregate, Landscaping, 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 Breccia and Siltstone
Here you can know more about Breccia and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Breccia and Siltstone consists of mineral content and compound content. The mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica 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 Breccia vs Siltstone, the texture, color and appearance plays an important role in determining the type of rock. Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors whereas, Siltstone is available in brown, red, reddish brown colors. Appearance of Breccia is Layered, Banded, Veined and Shiny and that of Siltstone is Rough. Properties of rock is another aspect for Breccia vs Siltstone. The hardness of Breccia is 7 and that of Siltstone is 6-7. The types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia whereas types of Siltstone are Not Available.
