摘要
We made Au grade fractal distribution and multi-element cluster analysis to theⅠand Ⅴgold ore bodies of the Xincheng gold deposit,and discussed their implication on superimposed mineralization.The Au grade of theⅠore body show multi-fractal distribution with fractal values at 2.2948 and 0.5845 which imply two stage superimposed mineralization.The Au grade of the Ⅴore body show single-fractal distribution with fractal value at 0.8831 which implies no superimposed mineralization.The multi-element cluster analysis shows that the Au has no obvious relation to other base metal elements,which indicate that the Au would be an independent mineralization event added by later Ag and other base metal mineralization.The Au grade fractal distribution and multi-element cluster analysis are all agree with previous studies on geological characters.
