biogeochemistry is a useful tool for assessing geochemical dispersion patterns. sari gunay epithermal gold deposit was selected in order to assess the application of biogeochemical exploration for gold in northwestern iran. in this study, four sites were sampled in a profile perpendicular to mineralized vein with a control site two km far-off mineralized vein. a sample from each dominant plant ...

The term "Carlin-type" deposit has been applied to a number of low-grade, sedimentary rock-hosted gold deposits that have been discovered and brought into production in the western United States since the 1960s. Carlin-type deposits are characterized by replacement of carbonate and silty carbonate rocks by silica, pyrite, barite, various arsenic, mercury, antimony, and thallium minerals and by ...

The paper presents the results of comprehensive isotope geochemical (Re-Os, Pb and ?34S) study sulfide mineralization Morozkinskoye deposit. ore zones deposit are localized in syenite massif Mount Rudnaya, which is located within Central Aldan region (southern Yakutia). Gold represented by vein-disseminated or vein type manifested acidic low-temperature metasomatites – beresites (Qz-Ser-Ank-Py)...

Abstract The paper comprises new analytical data on the nature and occurrence of gold in solid pyrobitumen, closely associated with main gold-bearing sulfide arsenic ores Bakyrchik deposit (Kazakhstan), related to post-collisional magmatic-hydrothermal origin. Gold mineralization occurs mainly form an “invisible” type structures arsenian pyrite arsenopyrite, gold-organic compounds pyrobitumen c...

We report the electrochemical characterization of chitosan films deposited at gold electrodes from an acidic solution at reducing potentials. Cyclic voltammetry was used to characterize the deposition and electroactivity of chitosan coated gold electrodes. Chitosan films were found to deposit at gold electrodes at potentials more negative than −1.0 V versus Ag/AgCl, a potential associated with ...
