sedimentary
Shale is a sedimentary rock, not a metamorphic rock.
Aluminum silicates with calcium, sodium, magnesium and many cations loosely bonded to the crystalline structure. some contain carbon from deceased life forms. It is the product of volcanic activity and tectonic plate activity with weathering and hydrolysis. Clays are ancient.
The weakest type of rock is generally considered to be shale, which is a fine-grained sedimentary rock composed of clay minerals. Shale is prone to breaking apart easily and has a low resistance to weathering and erosion compared to other types of rock.
Shale is a type of sedimentary rock composed mostly of clay-sized particles. It forms from the compaction of fine-grained sediments, such as clay and silt, and is characterized by its laminated or layered appearance. Shale is one of the most common sedimentary rocks found on Earth.
Shale is neither an element nor a compound. Shale is a type of sedimentary rock that is made up of a mixture of minerals, organic matter, and other materials.
