Airborne magnetic and radiometric datasets have, over the past few years, become powerful tools in identification of porphyry systems which may host economic copper–gold–molybdenum ore bodies. Magnetisation contrasts with unaltered rocks, coupled elevated signature, compared to rock, makes large-scale copper possible. Integrating these two different stream sediment data other geochemical explor...
The Grouh area is located about 19 km north-east of Sarduyeh city in Kerman Province. The major lithological units in this area include Eocene andesite and andesitic basalt. Oligo-Miocene intrusive units include diorite, quartz diorite and granodiorite; while pyroclastic units include tuff and breccia. The alteration in the Grouh area is remarkable due to the penetration of the intrusive masses...
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...
