Diagenesis of sedimentary rocks?
Diagenesis - Diagenesis is the process that turns sediment into rock. The first stage of the process is compaction. Compaction occurs as the weight of the overlying material… increases. Compaction forces the grains closer together, reducing pore space and eliminating some of the contained water. Some of this water may carry mineral components in solution, and these constituents may later precipitate as new minerals in the pore spaces. This causes cementation, which will then start to bind the individual particles together. Further compaction and burial may cause recrystallization of the minerals to make the rock even harder. Other conditions present during diagenesis, such as the presence of absence of free oxygen may cause other alterations to the original sediment. In an environment where there is excess oxygen ( Oxidizing Environmen t) organic remains will be converted to carbon dioxide and water. Iron will change from Fe 2+ to Fe 3+ , and will change the color of the sediment to a deep red (rust) color. In an environment where there is a depletion of oxygen ( Reducing Environment ), organic material may be transformed to solid carbon in the form of coal, or may be converted to hydrocarbons, the source of petroleum.

What is the difference between diagenesis and lithification?
Lithification is simply conversion of lose sediments into a solid rock due to pressure. Digenesis is the process that sediments go through after deposition. It includes all …the chemical, physical and biological changes that sediments go through before, during and after lithification. It is important to remember that digenesis takes place at low temperature and pressure compare to metamorphism, which is solid state recrystallization of Igneous, sedimentary and other metamorphic rocks occurs at high temperature and pressure.

Is there a relationship between diagenesis and orogensis?
Orogenesis: The process of mountain formation, especially by a folding and faulting of the earth's crust Diagenesis: The physical and chemical changes occurring during the …conversion of sediment to sedimentary rock. So, from one geologist to a non-geologist - I'd say no. (MORE)
