摘要

摘要: 通过对胶东新城金矿床金品位分形分布和多元素聚类分析，讨论多阶段成矿作用叠加信息。新城金矿Ⅰ号矿体的金品位分形分布具有分段拟合特征，分维值分别为2.2948和0.5845，说明存在两个阶段的叠加成矿作用。Ⅴ号矿体的金品位分形分布具有单一拟合特征，分维值为0.8831，说明不存在多阶段叠加成矿作用。多元素聚类分析显示，金元素与银及其他多金属成矿元素相关性较差，可能是独立的成矿作用，后期有银多金属成矿作用的叠加。金品位分形特征和多元素聚类分析得到的认识与前人通过地质研究得到的认识是一致的。

Abstract: We made Au grade fractal distribution and multi-element cluster analysis to theⅠand Ⅴ gold 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.
