Magmatic ore deposits may be defined as rocks of igneous origin (see IGNEOUS PROCESSES), which can profitably be mined for their constituent chemical elements.For example, the worth of annual global production from magmatic ore deposits exceeded $10 billion in 2001, and dominates or contributes significantly to world supplies of elements representing more than a third of the periodic table.

Metamorphism and Ore Deposits Metamorphic processes profoundly alter pre-existing mineral deposits and form new ones. The chief agents of metamorphism are heat, pressure, time, and various solutions. The materials acted upon are either earlier formed mineral deposits or ordinary rocks. Valuable nonmetallic mineral deposits are formed from rocks mainly through recrystallization and ...

2021-4-29 Mineral deposits formed as a consequence of sedimentary processes. Structural deformation may alter the form and attitude of some of these deposits. Lenticular masses, veins, lodes and zones of disseminated mineralization result from metamorphic processes. Recognition of the environment and existence of potentially economic mineral deposits may be based upon a variety of geological criteria:

In the metallic ore deposits areas, various interfering factors are serious, the noise has always been the most troublesome problem in seismic prospecting. During seismic data acquisition, the methods for increasing the energy of source could be used to enhance the effective signal strength, and some methods such as stack technique helps to suppress the external interference, including ...

China - China - Minerals: China’s most important mineral resources are hydrocarbons, of which coal is the most abundant. Although deposits are widely scattered (some coal is found in every province), most of the total is located in the northern part of the country. The province of Shanxi is thought to contain about half of the total; other important coal-bearing provinces include ...
