Abstract A variety of metals and deposit types define the metallogeny of the Andes from Colombia through Ecuador, Peru, and Bolivia to Argentina and Chile, although porphyry copper and epithermal gold deposits undoubtedly predominate and will continue to do so.

The Cenozoic mineralization in structures associated with the Red River shear zone (RRSZ) in northern Viet Nam includes the following mineralized ore types TR- (U-Th)-Pb-Zn and TR- (U-Th) –Ba-F, Au-Cu in the Song Da rift zone. The origin of the mineralizations is spatially and (possibly) temporally related to the formation of Paleogene potassic mafic –

Geodynamic Context of Metallogeny
2017Geodynamics is the dynamics of the Earth. Metallogeny is the genesis of metals, rather the metal-bearing mineral deposits. So, ‘Geodynamic context of metallogeny’ relates metallogeny to geodynamics. We generally refer to geodynamics in terms of plates and plumes, that ultimately control magmatism, sedimentation, and metamorphism and hence ore genesis ...

The precambrian metallogeny of India
Geology of Ore Deposits, 2009The data on the Precambrian metallogeny of India are integrated in order to provide insights into its basic principles and to create a digital cartographic representation of the results obtained. The description of an electronic map of the Precambrian of India on a scale of 1: 5000000 is an example of the creation of a GIS-oriented database on the ...

Metallogeny of Pennine Orefields
1989The North and South Pennine orefields have a long history of research, and the literature on their geology, mineralogy, mining history, ore parageneses and genesis is extensive. Comprehensive data for the North Pennine orefields were given by Dunham (1948) and Dunham and Wilson (1985) for the Alston and Askrigg areas, respectively.
