Definition

Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Felsite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Claystone vs Felsite 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 Felsite Reserves. Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay. Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition. 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 Felsite information and Claystone vs Felsite characteristics in the upcoming sections.
