成矿过程奇异性与矿产预测定量化的新理论与新方法
Singular mineralization processes and mineral resources quantitative prediction:new theories and methods
【摘要】 在分析地震、滑坡、洪水、暴雨、森林火灾等一系列非线性地球系统过程共同特征的基础上,笔者提出了成矿过程作为奇异性过程的命题。探讨了成矿过程奇异性、广义自相似性、自组织临界性等基本非线性特征的内在联系。从多重分形理论出发给出了:(1)度量成矿域空间结构不均匀性的局部奇异性分析模型;(2)度量成矿多样性与自相似性关系的系列广义自相似性度量模型;(3)首次给出了奇异性指标作为度量控矿要素与矿床分布相关关系的非线性模型,提出了从奇异性出发计算成矿后验概率的新的对数概率模型;(4)介绍了成矿奇异性的动力学模拟过程。详细介绍了非线性矿产资源预测理论和方法的基本内容和模型。
【Abstract】 Analyzing several types of non-linear hazardous processes such as earthquakes,clouds,landslides,rainfalls,floods,hurricanes and forest fires,the paper puts forward a proposition that mineralization processes can be considered as singular processes.The fundamental properties of singular processes including spatial heterogeneity and singularity,diversity and generalized self-similarity,and self organized criticality and fractal/multifractal distributions were discussed first and followed by an introduction to non-linear models for characterizing mineralization and for mineral deposit prediction.These models include a local singularity analysis model,generalized self-similarity models,and a log-probability model associating singularity of mineral deposit controlling factors(evidential layers)and posterior probability of mineral deposit.The contents of the newly proposed non-linear theories and methods for mineral resource prediction were introduced.
【Key words】 non-linear theory; complexity theory; mineralization processes; singularity; generalized self-similarity; self organized criticality; posterior probability; weights of evidence;
