These are processes that involve physical, chemical and biological changes, and end with the lithification of the sediment, that is, its transformation into sedimentary rock. The most frequent diagenetic processes are cementation, compaction, dissolution, replacement, and neoformation.

What are the basic processes of sedimentary rock formation?
The four basic processes rocks are: • Weathering – erosion of rock particles. • Transport – movement of list of afghanistan cell phone number database factors are responsible for metamorphism?
Metamorphism
The structure (factory) and composition of the original rock.
The pressure and temperature at which the system evolves.
The presence of fluids.
The weather.
What is the process of diagenesis? due to gravity, water and wind. • Deposition – accumulation of this sediment.
How are sedimentary rocks transformed?
If sedimentary rocks, due to movements of the Earth's crust, descend to deeper areas of the crust, they experience the action of high pressure and temperature, and are transformed into metamorphic rocks (metamorphism).
How are sedimentary rocks classified?
Sedimentary rocks are generally classified, according to the way they are produced, as detrital or clastic, and chemical or non-clastic; within the latter, there is a subcategory known as biochemical.
What is the porosity of sedimentary rocks?
The porosity of sedimentary rocks with this type of cement is high, unless the packing is complete or sutured. Pore cements: The TAB cement fills the pores between the grains and matrix, regardless of whether there is a previous contact cement between the grains.
