Exploration geochemistry continues to be a major contributor to mineral exploration programs at all scales. The decade has spanned a complete economic cycle in the minerals industry, during which there has been a change in exploration emphasis from the dominance of Au and diamonds to the addition of a range of base metals and the recent revival of U exploration. Increasing metal prices and the ...

The purpose of mineral exploration is to find ore deposits. The main aim of this work is to use the fuzzy inference system to integrate the exploration layers including the geological, remote sensing, geochemical, and magnetic data. The studied area was the porphyry copper deposit of the Kahang area in the preliminary stage of exploration. Overlaying of rock units and tectonic layers were used ...

in the centeral iranian volcanic belt (civb), north-west of shahre-babak, in area of javazm, dehaj and khabr, about 20 plutonic porphyritic tonalitic to granodioritic masses (1-50 km2) are intruded into a varity of rock sequences from eocene to early miocene in age. tonalitic and granodioritic rocks are some part of dehaj-sardoieh belt and having early miocene age. the civb contains intrusive a...

structural analysis of remotely sensed data provides a method of assessing the structural significance of large-magnitude regional metallogenesis in the kerman porphyry cu belt in the southern part of the central iranian volcanic belt. the role of large-magnitude ring structures in the distribution of hydrothermal alteration zones and porphyry copper deposits in the southern part of the kerman ...

All sorts of anomaly graphs of physical geography and geochemistry, such as aeromagnetic anomaly graphs, bouguer gravity anomaly graphs, regional geochemical anomaly graphs and so on, are all parameters for exploration deposit. And following the remote sensing image shortwave and infrared bands coming, researchers of remote sense have engaged in many highly effective experiments and have approv...

A new approach towards the composite structure of quarks and leptons in the context of the higher dimensional unified theories is proposed. Owing to the certain strong dynamics, much like an ordinary QCD, every possible vectorlike set of composites appears in higher dimensional bulk space-time, however, through a proper Sherk-Schwarz compactification only chiral multiplets of composite quarks a...

introduction several valuable calcite deposits are located in ghare-gheshlagh, south basin of urmia lake, nw iran. ghare-gheshlagh area is situated in the northern part of tectono-sedimentary unit, forming nw part of tertiary sanandaj-sirjan geological belt (stocklin and nabavi, 1972). the predominant rock types of the area include light color limestones (qom formation) and quaternary alluviums...

The metamorphosed mafic-ultramafic sequences of the Eastern Andean Metamorphic Complex outcropping in Patagonian Andes are critical to disclose late Paleozoic tectonic evolution southwestern margin Gondwana. In study area, bodies thrusted onto polydeformed metasedimentary rocks and intruded by mid-Carboniferous composite Leones Pluton. metabasalts (mostly tremolite-chlorite schists amphibolites...
