摘要:

从非线性科学在矿产资源中的勘察、评价、异常识别等应用角度出发,尤其是多重分形理论的应用,本文引入一种新的多重分形谱估计方法——累积量估计。鉴于对数正态和对数泊松分布在矿产资源勘察中的重要地位,本文首先通过对数正态(LogNormal Multiplicative Cascade Process,CMCLN)和对数泊松(LogPoisson Multiplicative Cascade Process, CMCLP)多重级联过程模拟数据验证,其次针对云南个旧锡矿区Cu、Pb水系沉积物元素富集值的分布进行多重分形分析,结果表明,对应于均值周围的谱段累积量估计给出了精确且稳定的估计,基本可以满足一般的地学信息处理要求。

Abstract:

This paper, based on the application of non-linear science, specially the multifractal theory, in exploration, evaluation and telling anomalies of mineral resources, adopts a new method multifractal spectrum estimation on cumulative quantities to verify the lognormal multiplicative cascade process (CMC-LN) and the log-poisson multiplicative cascade process (CMC-LP), which play an important part in minerals exploration, calculates the Cu and Pb elements enrichments in the stream sediments in Gejia Tin mine district, Yunnan province. The results return a precise and stable estimation of spectrum cumulative quantities around the mean values. The method can meet the requirements of geological information processing.

Key words: Log-Normal Multiplicative Cascade Process (CMC-LN), Log-Poisson Multiplicative Cascade Process(CMC-LP), cumulative analysis
