In gold-endowed greenstone belts, ore bodies generally correspond to orogenic gold systems (OGS) formed during the main deformation stage that led craton stabilization (syntectonic period). Most OGS deposits postdate and locally overprint magmatic-hydrothermal systems, such as Au-Cu porphyry mostly magmatic (synvolcanic period) polymetallic intrusion-related (IRGS) of syntectonic period. Porphy...

The energy change per electron in a chemical or physical transformation, ΔE/n, may be expressed as Δχ̅ + Δ(VNN + ω)/n, where Δχ̅ is the average electron binding energy, a generalized electronegativity, ΔVNN is the change in nuclear repulsions, and Δω is the change in multielectron interactions in the process considered. The last term can be obtained by the difference from experimental or theoreti...

Porphyry deposits are copper-rich orebodies formed by precipitation of metal sulphides from hydrothermal fluids released from magmatic intrusions that cooled at depth within the Earth's crust. Finding new porphyry deposits is essential because they are our largest source of copper and they also contain other strategic metals including gold and molybdenum. However, the discovery of giant porphyr...

Deep-seated mineralization prediction is an important scientific problem in the area of mineral resources exploration. The 3D metallogenic information extraction geology and geochemistry can be great help. This study uses modeling technology to intuitively depict spatial distribution orebodies, fractures, intrusive rocks. In particular, geochemical models 12 elements are established for extract...

Despite the existence of a well-known set forecast and search criteria, only three gold silver epithermal deposits were discovered on territory Amguem-Kanchalan metallogenic zone, which has significant resource potential. The base enterprises developing them is extremely limited. aim study to clarify regional local conditions for localization gold-silver mineralization, forecasting searching pr...

west directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones. the tectonomagmatic and metallogenic setting of the lut block is still a matter of debate and several hypotheses have been put forward. despite some authors denying the influence of ...
