| 摘 要： | Gold abundances iu granitic rocks of differeat geological periods of Southern China were estimated. A review of the quantitave data now availabe indicates that unaltered granitic rocks have a rather restricted range in gold content, rarely exceeding 4 ppb and generally range from 1.4 to 3.3 ppb.Mean gold content tends to decrease from basic to acid granitoids. This tendency suggests that gold is not concentrated in the residual silieate melt during the formation of granitic rocks. Abundance dtata for granitoids in Southern China provide no geochemical clues or guides to distinguish areas favorable or unfavorable for gold mineralization, but they are necessary to establish background values for various rock types.
