They are formed both biochemically and mechanically.
6 Metamorphic Rocks – An Introduction to GeologyBurial metamorphism commonly occurs in sedimentary basins, where rocks are buried deeply by overlying sediments. As an extension of diagenesis, a process that occurs during lithifiion, burial metamorphism can cause clay minerals, such as smectite, in .
Reading: Characteristics of Sedimentary Rocks | GeologyThe common names of clastic sedimentary rocks—conglomerate, sandstone, siltstone, and shale—are based solely on grain size. However, there are more precise names within these broader egories that are based on clastic sediment features other than grain size.

Shale: Sedimentary RockShale is a finegrained sedimentary rock that forms from the compaction of silt and claysize mineral particles that we commonly call "mud." This composition places shale in a egory of sedimentary rocks known as "mudstones." Shale is distinguished from other mudstones because it is fissile and laminated. "Laminated" means that the rock is ...

Sedimentary Rocks22/10/2013 · Common Structures and Textures of Sedimentary Rocks Cementation • Conglomerates, breccias and sandstones are the important sedimentary rocks which are formed mainly due to cementation, In these, finer material act as the binding medium in between the coarser constituents.
What are the 3 most common types of sedimentary rocks ... · Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash.
