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...

This paper documents the exploration significance of Ag/Au, Au/Cu, Cu/Mo and (Ag×Au)/Cu×Mo) ratios of the supra-ore and sub-ore halos versus fluid inclusion evolution for 24 Cu, 6 Cu- Mo and 10 Cu-Au porphyry deposits worldwide. The ratios are based only on the economic and mineralized hypogene alteration zones. The results indicate that (Ag×Au)/(Cu×Mo), Au/Cu and Cu/Mo ratios increase with dec...

Abstract The 1,500-km-long Banatitic Magmatic and Metallogenetic Belt (BMMB) of Romania, Serbia and Bulgaria is a complex calc-alkaline magmatic arc of Late Cretaceous age. It hosts a variety of magmatic-hydrothermal Cu, Au, Mo, Zn, Pb and Fe deposits, including Europe’s only world-class porphyry-copper deposits. Regional metallogeny can be linked to subduction of the Vardar Ocean during the La...

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 ...

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...

Detection of deep and hidden mineralization using the surface geochemical data is a challenging subject in the mineral exploration. In this work, a novel scenario based on the spectrum–area fractal analysis (SAFA) and the principal component analysis (PCA) has been applied to distinguish and delineate the blind and deep Mo anomaly in the Dalli Cu–Au porphyry mineralization area. The Dalli miner...

1. The ability of organic and inorganic sulphur to influence the copper and molybdenum metabolism of sheep was compared in a series of three 2 X 2 factorial design experiments. In each experiment, four groups of five to seven hypocupraemic ewes were repleted with a basal diet supplemented with 6 mg Cu/kg and containing S and Mo at one of two concentrations, 1 or 4 g S and 0-5 or 4-5 mg Mo/kg re...
