Rock formation, concentration, or disposition of various elements, participation of substances in water, limestone formation from calcareous skeletons are geochemical processes and are done, more or less, with living matter.

Essential is that in the process of life, all organisms on earth, plants and animals, are extracting or consume enormous mass of matter. The speed of this process is particularly significant in the lowest organisms: algae, bacteria and other lower organisms. Calculations show that in this process enter a quantity of matter a thousand times greater than that which is contained at that time,in all land-plant and animals.

Organisms build their body entirely of elements that derive from substances found in nature that surrounds them: water, air and soil. Home substance component of all organisms is - water-H2O, found on average 80%.Carbon - C plays a major role in the structure of bodies,  forming thousands of compounds with hydrogen, oxygen, nitrogen, sulfur and phosphorus (H, O, N, S, P), forming proteins, fats, carbohydrates , complex organic compounds, etc..In bodies are always found: Calcium, especially in the skeletons, and Potassium-K and Iron-Fe.

Geochemical role of concentrating organisms is perfectly understandable, for example, marine invertebrates, absorb from the sea water or marine mud-Vanadium-V, which is found in small amount, and after their death, vanadium remains as concentrated in marine sediments.

Algae absorb from the sea water-Iodine-I, which is found in tiny amounts, then it comes along with the remains of seaweed on the sea bed. In the rocks that form later from the sludge are separated mineral iodine waters.

The Geochemical process is also known as the Geochemical cycle.  In the cycle natural separation and concentrentation of elements ooccurs with the onset of heat.  The studies of the evolutionary changes involved in the oceans have long included how the geoprocess effects the changes.  he elements identified in the process are part of the earth's crust and subcrust.  Areas of studies include the lithosphere, hydrosphere, and atmosphere as well.

The effects of global warming have a strong relationship with the geochemical process and scientists are trying to determine how to stop the warming cycle.  There are many other avenues for research in this area with the United States leading the way in the effects as they pertain to water and atmospheric changes.

It is difficult to narrow the reasons for the cycle to occur as it occurs in many different situations in science.
