Claystone.
ARGILLITE
Clay is actually a description of sediment of a specific particle size. As such clay is not necessarily a rock. However when compacted and cemented clay forms claystone which is a sedimentary rock.
Clastic sedimentary rocks, like shale and sandstone.
Shale is made from layers of mud and clay pressed together. :)
sedimentary
The most common sedimentary rock formed from mud or clay is shale. Shale is a fine-grained sedimentary rock made up of compressed and hardened clay and silt particles. It typically exhibits a characteristic fissile (easily splitting into layers) structure.
Siltstone is a fine-grained sedimentary rock consisting of consolidated silt.
This is Shale, a Sedimentary rock.
Sedimentary rock.
The type of rock made of hardened sediment is called sedimentary rock. Sedimentary rocks are formed through the accumulation and compression of sediments such as sand, silt, and clay over time. Examples of sedimentary rocks include sandstone, shale, and limestone.
Shale is a sedimentary rock formed from the compaction of fine-grained sediment such as mud or clay.
Claystone, and shale are sedimentary rocks formed from lithified deposits of clay.
