大水金矿床是著名的超大型矿床.在借鉴前人矿床地质研究成果的基础上,通过对矿体规模数据的多重分形特征及吨-品位关系研究,揭示了成矿过程中资源量生长的数量规律.矿体长度服从简单分形分布,矿床资源量的吨-品位关系能用指数函数或直线方程更好地拟合,矿床与矿体资源量双对数图、吨-品位的双对数图的多重分形特征表明:在分形构造成矿空间中,特定成矿阶段的矿床资源量的生长方式是自组织非线性增殖过程,与自组织有关的随机性使吨-品位关系趋于指数关系;在整个成矿过程中,矿床资源量的生长方式是各阶段矿体资源量的线性叠加.进一步根据熵最大化原理及效用理论导出了与统计结果吻合的矿床吨-品位方程,并得到柴家庄金矿矿体地质数据的验证.
Dashui gold deposit is a famous super-large deposit.Based on the research results of predecessor deposit geology, the multifractal characteristics and tonnage-grade relationship of ore body size data are used to reveal the growth of resources in the process of mineralization The number of ore bodies obeys the simple fractal distribution, the tonnage-grade relationship of ore resources can be better fitted by exponential or linear equations, the logarithm of ore resources and the logarithm of t-grade The multifractal characteristics of fractal structure show that the growth pattern of mineral resources in a particular ore-forming stage is self-organizing nonlinear propagation in a fractured tectonic metallogenic space and the t-grade relationship tends to be exponential with the randomness of self-organization In the whole process of mineralization, the growth pattern of ore resources is a linear superposition of ore resources in each stage.According to the theory of entropy maximization and utility theory, the tonnage-grade equation of ore deposits is deduced according to the statistical results, Verification of geological data of ore body in Jiazhuang Gold Mine.
