NAA of Au in a number of minerals from different intrusive and skarn rocks enables calculation of a coefficient of accumulation (Ka) which indicates a persistent accumulation of metal in all intrusive rocks studied (Ka 1.3-3.5) in the fine-grained rock matrix. Higher Au concentrations in minerals of pegmatites and contact-metasomatites (Ka 20-190) indicate substantial Au accumulation. Experimental data indicate the ratio of partition of Au between fluid phase and ore-generating granitic melt is approx 50. -S.R.
