The Jiadi gold deposit, situated in the Southwestern region of Guizhou, is a large-scale, recently discovered, basalt-hosted, and fine-grained disseminated deposit. This study has unveiled that tectonic deformation deposit can be categorized into four stages: Late Paleozoic crustal uplift brittle (D1-deformation) stage; Early Yanshanian NW-trending compressive ductile (D2-deformation) NS-trendi...

introduction the mahour exploration area is a polymetallic system containing copper, zinc and silver. the mineralization can be seen in two forms of veins and disseminations. this area is structurally within the lut block, west of deh-salm village. recent exploration work and studies carried out by geologists on this volcanic-plutonic area of lut demonstate its importance indicating new reserve...

Typomorphic features of placer gold conglomerates the Ortokinskaya formation Early Permian age (P1or) Sololiy Uplift Olenek High and modern channel alluvium Ortoku Eekit river, which drains these deposits, are studied. It is found that extremely heterogeneous composition complex inner structure typical vast majority conglomerates. There several stages different fineness (from 251‰ to 999‰) with...

in order to assess the potential of copper mineralization and its associated elements in soltan meydan basaltic formation situated in the north of shahrud, the method of stream sediment and heavy mineral has been used. to achieve this aim, totally 68 samples of sediments (-80 mesh in particle size) and 6 samples of heavy minerals (-20 mesh in particle size) have been collected in an optimized n...

Orogenic gold deposits are currently the world’s major source of Au, but uncertainty exists in timing mineralization relative to ages host rocks, metamorphism, and magmatism. Consequently, origin detailed evolution ore-forming fluids have long been elusive. Apatite occurs widespread various types mineral can provide valuable information on ore genesis. Here, we present textural, high-precision ...
