geochemical anomaly
An unusually high concentration of one or more chemical elements in a sample of rock, soil, vegetation, water, or a high concentration of hydrocarbons in soil, which often indicates a nearby mineral deposit.
geochemical balance
1. The study of the global distribution and the migration of a particular element, mineral, or compound, including the amount liberated by weathering and transported to earth sediments and oceans.
2. The proportional distribution, and the migration rate, in the global fractionation of elements, minerals, or compounds; for example, the distribution of quartz in igneous rocks, its liberation by weathering, and its redistribution into sediments and, in solution, into lakes, rivers, and oceans.

Sediments refer to solid fragments of inorganic or organic material that come from the weathering (disintegration and decomposition) of rock and are carried and deposited by wind, water, or ice.

geochemical cycle (s) (noun), geochemical cycles (pl)
The successive stages in the circulation and migration of chemical elements among the lithosphere, hydrosphere, and atmosphere during geological changes.
geochemical evolution
1. Over geological time, any change in the chemical composition of some section of the earth; such as, the oceans.
2. Any alteration or change in the chemical composition of a rock in which the amount of a particular component exceeds the amount present in the parent rock.
