geochemical exploration

Many geochemical features are common to soils developed under a wide range of physical and climatic conditions and thus permit the widespread use of geochemistry in exploration. If a surface geochemical anomaly is present, the intensity, areal extent, and quality of the anomaly cannot determine the economic viability of the accumulation of depth, but there is a significant increase in the success rate. In some areas of the world, mine workers are essentially treated as slave labor, another factor that contributes to the controversy over geochemical exploration and the subsequent mining of resources.

Petroleum products are also used in the manufacture of plastics, which are found in product packages, dishware, toys, jewelry and a myriad of other common household products. The objective is to find some dispersion of elements or compounds sufficiently above normal to be called an anomaly, which may indicate mineralization or hydrocarbon accumulations.
