摘　　要： 成矿元素含量分布具有不规则性和自相似性,运用适当的模型来刻画成矿元素分布的整体规律是实行进一步地质预测的重要基础.针对山东某矿成矿元素的统计特征,采用可有效描述元素的自相似性和长程相关性的稳定分布模型对其分布特征进行刻画.结果显示,稳定分布模型可较好地描述该金矿成矿元素的分布特征,是系统和全面刻画成矿元素品位分布规律的有效模型之一. The abundance distribution of metallogenic element has irregularity with self-similarity. It is an important basis of further geological forecast to use suitable models for depicting the holistic law of metallogenic elements distribution. Considering the statistic features of metallogenic element in a gold deposit, Shandong, China, the stable distribution model, which can describe both its self-similarity and long-range correlation effectively, has been applied to depict the distribution characteristics there. The results show that the stable distribution model can describe better the distribution features of metallogenic element in the gold deposit and is one of the effective models to depict the abundance distribution laws of metallogenic element systemically and overall.
