成矿预测理论与方法新进展 摘要：成矿预测研究的历史与人类进行矿产勘查的历史紧密联系，随着找矿难度的增大，成矿预测对勘查工作的指导作用越来 越重要。现代地质科学的重要特征是冲破学科的界线，立足于整个地质学的高度进行跨学科的联合攻关，方能在理论上和技术 方法上有所创新。论述与总结了一些现有成矿预测新方法的特点，包括美国“三步式”固体矿产资源潜力评价方法、成矿系列缺 位预测法、基于GIS 的综合信息预测法及人工神经网络、多重分形等非线性数学预测方法。这为今后进行成矿预测时在方法选 择上提供了一些有益的建议和参考。 关键词：成矿预测；综合信息；人工神经网络；地理信息系统；模糊逻辑 中图分类号：P612 文献标志码：A 文章编号：1671-2552（2010）06-0953-08
Hou C X, Shen W. New method and theory of metallogenic prediction.
Geological Bulletin of China, 2010, 29(6):953-960 Abstract： Metallogenic prediction research history is closely related to human's mineral exploration. With the increasing difficulty of prospecting, it's indicated that metallogenic prediction can be an important guide to mineral exploration. An important characteristic of modern geosciences is breach of discipline the restriction. Thus focus on the whole geosciences, to conduct jointly inter-disciplinary research, we can obtain theoretical and technical innovations. This paper has summarized characteristics of several existing metallogenic prediction methods, such as "three-step" solid mineral resources evaluation method form USA, Vacancy of Metallogenic Series Prediction, Synthetic Metallogenic Prognosis Method Based on GIS, Artificial nerve network, and Multi-fractal non-linear methods for mineral resource prediction, which will provide useful reference to metallogenic prediction in future. Key words: metallogenic prediction; comprehensive information; artificial nerve network(ANN); GIS; fuzzy logic 成矿预测研究现状及发展趋势

Abstract :The ore-finding is more difficult because the
outcropping and recognizable ore deposits are very few .Fortunately , the spread application of high-tech GIS shows a new advance in the metallogenetic prognosis .According to a historic review of metallogenetic prognosis , we put forward the main thoughts and working steps of future meltallogenetic prognosis in geological exploration working , ie , to realize scientific , systematic , informative , dynamic , visible multiple information comprehensive prognosis and ore-finding under direction of new metallogenetic theory and using GIS technique in oreder to provide the basis for approval ore prospecting project .

Zhao Pengda. Quantitative mineral prediction and deep mineral
exploration. EarthScience Frontiers , 2007 , 14(5):001-010 Abstract :This study is a brief review of the char acte ristics of mine ral prediction and assessment. The necessity of quantita tive prediction is due to the unce rtainty of predictio n caused by the diver sity of miner al depo sit types , the complex ity of mineral depo sit g ene sis, the implicitne ss of mine ral de po sit co nt rolling facto rs a nd the no n-unique under standing of the e xplo ratio n info rmatio n. The multiple character s of mineral sy stem s (multiple types , sca les , levels , e lements and subsy stems) also make it necessa ry to predict miner al deposits quantitatively. Fo r discove ring supe r-la rge depo sits , the principle o f “ similar-a nalogy” is no t suitable , and the principle of “finding diffe rences” must be applied. A case study o f the geo anomalie s of the Gejiu Tin depo sits demonstra tes the close relatio nships betw een different g eo anomalies and the spa tial distribution of tin o re bo dies. The paper also discusse s sever al to pics co ncer ning the deep mine ral depo sits, w hich a re the main pro blems facing the current mineral ex plo ratio n. The se topics are the kinds of deep ex plo ratio n, the co ncepts of so called “ seco nd mine ral e xplo ration space” , the impo r tance o f studie s on the deep structures o f Ear th crust , the impo rtance of high “eco nomic r eturn ra te” and hig h “co nv ersio n rate” , and the difficulties o f determination o f an ex plo ratio n object being a commercia l one , ev en the object being a super-la rge depo sit.
