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...

The Xinjiazui gold deposit, a newly discovered is situated in the northwestern margin of Yangtze Block, China. source and genesis mineralization are poorly understood. It urgent to use H–O isotopic composition quartz geochemistry pyrite evaluate origins Au ore-forming fluids this deposit. Three types were identified, including synsedimentary framboidal pyrites (Py0), directional arrangement pre...

This work investigates the electrochemical study of glutathione self-assembled monolayers (SAMs) prepared from aqueous solution on gold and platinum surfaces. The deposit SAMs monolayers were characterized by cyclic voltammetry and electrochemical impedance spectroscopy methods. In addition, the interpretation of electrochemical impedance spectroscopy results was based on the charge-transfer re...

Literature is well supplied with studies of gold deposit on mica for fabricating ultra-flat template-stripped surface. Gold silicon has not received much attention. Our study optimizes the deposition rates, annealing temperatures and time to obtain a surface very low roughness large (111) oriented crystallites. Atomic force microscopy performed in tapping peak mode evaluate roughness. The cryst...

in this study, the reliability of the primary gold mineralization exploration using multispectral etm+ imagery was investigated in lahroud region, northwest iran, which was conducted by integration of alteration and structural indicators. co-occurrence of the clay minerals and iron oxides is an important criterion in gold deposit exploration; therefore, their alteration zones were mapped using ...

An electroless deposition method comprised of seed formation and subsequent seeded growth is developed for the decoration of surface-grown single-walled carbon nanotubes (SWCNTs) with gold nanoparticles of controlled size and interparticle distance. The density of the gold nanoparticles is determined by the density of seeds. Gold seeds are used for the SWCNT arrays grown on SiO(x)/Si substrates...

The formation of gold microparticles on a silicon substrate through the use of energetic surface plasmons is reported. A laser-assisted plasmonics system was assembled and tested to synthesize gold particles from gold thin film by electrical field enhancement mechanism. A mask containing an array of 200 nm diameter holes with a periodicity of 400 nm was prepared and placed on a silicon substrat...

A comparative analysis of typomorphic features gold placers and indigenous sources was carried out for the Glukharinsky ore-placer node (the Nadezhda deposit Glukharinskoye, Tyomnoye, Tyi-Jurye ore occurrences). correlation between fineness placer native composition relic minerals preserved inside particles obtained first time. This made it possible to establish mineral parageneses from potenti...
