Minerals-companions of microsized and nanosized gold at the deposit Pioneer (Amur region)

For the first time it was obtained data on minerals-companions of microsized and nanosized gold at the Pioneer Gold Deposite. The main minerals-companions of gold are quartz, adular, pyrite, silver telluride (hessite), stibnite and sulphoantimonites. For all ore types the growth of free gold occurred on a single mechanism - from nanoparticles close to spheroidal one to formation the free gold membrances.
