Foremost would be pressure, usually from burial by additional sediments. The other processes take it from there.
== == Clastic sedimentary rocks.
The class of sedimentary rocks that are made of fragments from rock minerals and shells is called alabaster. It is a fine-grained sedimentary rock.
A sedimentary rock made up of rock fragments or particles of other rocks is called 'clastic'.
Geo-thermal force is needed in forming the sedimentary rocks. The fragments of igneous rocks by erosion are carried by water currents and deposited in the basin for millions of years. The upheaval in the earth strata bring these deposits deep. The pressure of earth mass and its heat converts these deposits in to sedimentary rocks. The red sand stone is the best example of sedimentary rock formation.
Clastic rocks are made from fragments of pre-existing rocks.
Sedimentary rocks of weathered rock fragments are called clastic rocks.
Bioclastic sedimentary rocks.
No. The rocks you describe are clastic or detrital sedimentary rocks.

as fragments of rock
A sedimentary rock made up of rock fragments or particles of other rocks is called 'clastic'.
Some sedimentary rocks are particles and rock fragments that become cemented together. Examples of sedimentary rocks are chalk, sandstone, limestone and shale.
