Controls on the heterogeneous distribution of mineral ...

Abstract. Mineral deposits exhibit heterogeneous distributions, with each major deposit type showing distinctive, commonly unique, temporal patterns. These reflect a complex interplay between formational and preservational forces that, in turn, largely reflect changes in tectonic processes and environmental conditions in an evolving Earth.

Tectonic and lithospheric controls on the

Mineral deposits exhibit extremely heterogeneous distributions, with each major deposit type showing a distinctive, commonly unique, temporal pattern. Individual temporal patterns reflect a complex interplay between formational and preservational forces that, in turn, largely reflect changes in tectonic processes and environmental conditions in an evolving Earth.

Mineral Deposits National Geographic Society

The mineral extraction process begins with finding the location of mineral deposits. Remote sensors that use satellite images and geochemical surveys are just two ways that minerals can be located. Many minerals are then removed through mining or quarrying. However, liquid minerals, such as oil or gas, may be extracted by pumping.
