    摘要:

    本文对胶东地区的石英脉型和蚀变岩型金矿床的储量分布进行了研究。结果表明,金矿床的储量服从多重分形分布,且具有普遍意义。金矿床的储量分形结构是成矿系统处于混沌边缘的一种表现形式。分维D值的地质意义与研究范围有关,就胶东金矿带而言,它可用于划分蚀变岩型和石英脉型矿床。

    Abstract:

    Because of different properties of orecontrolling structures, deposits in Jiaodong area have been divided into two types of mineralization: quartz veins type and altered rock type. Reserve distribution of these two types of deposits has been discussed by fractal models. It is shown that reserves of gold deposits obeys mult ifractal distribution. This phenomenon seems to be a general rule. It is suggested that frequency distribution pattern of the reserves of gold depositsis an expression of the fact that metallogenic system evolves on the edges of chaos.The geological meaning of fractal dimension D will be changed with the scope of studied area.In the Jiaodong ore zone, D can be used to distinguish quartz vein type and altered rock type gold deposits.
