Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.   
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Claystone vs Scoria Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Claystone and Scoria Reserves. Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Claystone vs Scoria information and Claystone vs Scoria characteristics in the upcoming sections.
