Abstract Porphyry-type deposits are the main global source of copper and molybdenum. An improved understanding most favorable structural settings for emplacement these is necessary successful exploration, particularly considering that future discoveries will be made under cover based on conceptual target generation. A common view porphyry preferentially emplaced in pull-apart basins within stri...

The Shand Cu-Mo deposit is located in the Orkhon-Selenge depression, Northern Mongolia. It lies near Erdenetiin Ovoo porphyry deposit, which together define one of Mongolian’s most economically significant metallogenic belts. In (Au?) several ore related breccia types are associated with porphyritic granodiorite intrusions, and they contain pre-, synand post-mineralized stocks, magmatic-hydroth...

Abstract: The Urumieh-Dokhtar Magmatic Belt (UDMB) is the host of many Iranian Cu porphyry deposits. Southern part of this belt, in the range of geological Jebal barez, has been less investigated because of the mountainous and rough topography and also some security confrontation. Porphyry deposits are associated with hydrothermal alteration zones can be mapped using remote sensing data such as...

The Kalmakyr deposit in Uzbekistan is one of the world’s largest gold-rich porphyry Cu deposits, and mineralization was proposed to be closely associated with emplacement latest intrusive phases, that is, granodiorite porphyry. However, it still unclear which features these ore-bearing intrusions are crucial for enormous metal enrichment how they correlate magmatic fertility. In this study, we ...
