Abstract The Huayangchuan ore belt is located in the western segment of Xiaoqinling Orogen southern margin North China Craton (NCC), and hosts voluminous magmatism significant U?REE?Mo?Cu?Fe polymetallic mineralization. However, geochronological framework various mineralization phases this region poorly understood. Here, we present new Re?Os isochron ages on magnetite from Caotan Fe deposit (2 ...

Intrusive rocks related to porphyry copper mineralization are part of the wide diversity of subduction-related, mantle-derived, igneous rocks generated in convergent margin settings. What differentiates them from barren igneous rocks results ultimately from the multi-component and multi-stage processes that condition magma composition in these settings. Unfortunately, the petrogenetic history i...

This work aims at figuring out the spatial relationships between the geophysical and geological models in a case study pertaining to copper-sulfide mineralization through an integrated 3D analysis of favorable target. The Ghalandar Skarn-Porphyry Cu Deposit, which is located in NW Iran, is selected for this research work. Three geophysical surveys of direct current electrical resistivity and in...

This article describes the geology and industrial mineral potential of corundum, pyrophyllite and andaluite at the Empress deposit in the Taseko Lakes area (Figure 1). The Empress is a copper-goldmolybdenum porphyry deposit located 225 kilometres north of Vancouver and 50 kilometres northwest of Goldbridge and the Bralorne mining camp. Fine-grained corundum, in association with andalusite-pyrop...

Abstract Detailed mineralogical and textural studies, combined with sequential X-ray diffraction geochemical modeling, helped to solve the “copper pitch/wad” enigma in Exótica deposit located downstream of Chuquicamata porphyry copper deposit. Copper pitch wad are essentially chrysocolla co-precipitated Mn oxides, mainly birnessite, as well pseudo-amorphous oxide/oxyhydroxides. Linking mineralo...

The Sungun porphyry copper deposit is located in northwestern Iran and is associated with diorite/granodiorite to quartz-monzonite of Miocene age, which intruded Eocene volcanosedimentary and Cretaceous carbonate rocks. Copper mineralization was accompanied by both potassic and phyllic alteration. Three main mineralization related alteration episodes (potassic, transition, and phyllic alteratio...
