The Dongxiang tungsten–copper deposit is a large W–Cu located in the northeast of Jiangxi province south China. Previous studies have mainly considered geochemical and isotopic attributes ore deposit, but information still lacking on genesis setting mineralization-related intrusive rocks. This paper presents systematic elements Sr–Nd–Hf data granodiorite porphyry. porphyry intermediate–acidic c...

The genesis of deeply buried deposits in the Duobaoshan ore district, largest porphyry-related Cu-Mo-Au field northeastern China, is not well understood and their exploration lacking because fine velocity structure this region comprehensively understood. Herein, first-arrival seismic travel times were picked along a deep reflection profile inverted using tomographic method to obtain detailed up...

Whole-rock geochemical data and compositional balance analysis (CoBA), combined with a magnetic susceptibility model obtained from high-precision survey, are useful exploration tools in the Jiama porphyry–skarn deposit, southern Tibet, China. In this paper, three innovative aspects of described that have assisted deposit: an improved geological understanding thrust–nappe structure, hydrothermal...

There are scattered exposures of young volcanic rocks in Hamun Lake Area in south western and north western of Zabol in east of Iran. The microscopic evidences and geochemical analysis show that these rocks are olivine basalt and basalt to trachy basalt. The main textures of these rocks are porphyry, microlitic porphyry and vesicular. The main phenocrysts of these rocks are olivine, clinopyroxe...

Chah Torsh intrusive body in S-W of Nadushan is a small part of extensive magmatism of Oligo-Miocene age in Urumieh-Dokhtar magmatic belt. This is the largest intrusive mass of SW of Nadushan complex which are all outcropped as masses cut through Eocene volcanics. The Chah Torsh intrusion consists of two phases with porphyry and granular textures. Geochemical properties of two phases on the bas...

The Vathi porphyry Cu-Au ± Mo mineralization is located in the Serbo-Macedonian metallogenic province of Western Tethyan Metallogenic Belt. It mainly hosted by a latite and genetically associated with quartz monzonite intrusion, which intruded basement rocks Vertiskos Unit latite, 18 to 17 Ma ago. A phreatic breccia crosscuts latite. was affected potassic alteration, whereas subjected local pro...

Porphyry copper ore is a vital strategic mineral resource. It often associated with significant hydrothermal alteration, which alters the original mineralogical properties of rock. Extracting alteration information from remote sensing data crucial for porphyry exploration. However, current method extracting ASTER does not consider influence disturbing factors, such as topography, and ignores we...

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...
