【副题名】多目标矿产预测评价理论与实践探讨

【摘要】 把地质异常、成矿多样性、矿床谱系三者进行有机关联与综合研究作为矿产预测评价切入点的“三联式”成矿预测，是矿产预测评价研究领域的创新探索。本文以矿产系统勘查为目的，提出了“多目标矿产预测评价”新理念，并在“三联式”成矿预测理论指导下，较系统地开展了不同尺度下的多目标矿产预测评价新探索。初步构建了“三联式”多目标矿产预测评价的理论框架与方法基础，并在实践中取得明显成效。 本文主要结论与研究成果： 1、“三联式”成矿预测的理论核心是“求异”。求异是创新之源、求序之本，更是多目标矿产预测评价之关键。充分认识地球矿物质组成的不均一性、多样性、多变性、共生性和多用性等特征与规律，在求异的基础上求序，在求序的指导下进行科学预测与评价。 2、多目标矿产预测是矿产系统勘查的理论依据与技术途径。必须树立科学的地球资源现，贯彻“综合性、系统性、整体性、实践性”等预测评价基本准则，根据勘查阶段与尺度要求，逐级开展多目标找矿预测与评价。 3、在区域致矿地质异常解析，成矿多样性分析和矿床谱系研究的基础上，系统建立找矿预测模型，定量圈定和优选不同矿产预测靶区，是区域多目标矿产预测评价的基本途径。本文实例(滇西北地区喜山期富碱斑岩相关矿产)研究，圈定不同类型找矿有利地段预测靶区：重晶石类6个；Cu-Au-Mo类4个；Pb-Zn-Ag-Au类5个。并对预测靶区进行了分类解剖，预测和新发现：隐伏矿体(热液脉型Pb-Zn-Ag-Au矿)4个；不同成因类型的重晶石矿体远景地段5个，预测成矿远景规模可达大型-特大型。 4、矿床多目标预测评价是实现“无废矿业”之基础。本文实例(西沟超基性岩体)研究，较系统地查证西沟超基性岩体为一颇具资源潜力的综合性“矿床”。初步创建了该超基性岩体由浅部到深部，由蛇纹岩矿、装饰石材矿到金属-贵金属矿的“立体勘查-系统评价-综合开发模式”。 5、矿体多目标预测评价是“综合利用”与“最佳利用”研究之基础。本文实例(穆棱沸石矿)研究，系统地探讨了不同类型沸石矿体的矿化特征、矿石类型、矿化组分、矿石品级和物化性能的多样性、多变性特征与空间变化规律，以及矿石组分与物化性能之间的相关规律；提出并初步建立了不同类型沸石矿的岩矿地球化学预测评价模式；发现并初步查证：高品级的丝光沸石矿体1个，丝光一斜发混合型矿体1个。在此基础上探讨了研究区不同矿体以及矿体不同部位沸石矿的多目标开发利用研究方案。更多还原

【Abstract】 The "Three-component" mineral prediction is a new theory and approach of mineral prospecting by the synthetic combination and comprehensive studies of geo-anomaly, diversity of mineralization and spectrum of mineral deposit. In this thesis, to the purpose of systematic mineral prospecting the new argument of "Multi-objective mineral prediction and assessment" has been put forward. Based on the theory of the "Three-component" mineral prediction, the multi-objective mineral prediction and assessment has been systematically practiced in different areas and in different scales. The theoretical frame and method basis of the ’Three-component" multi-objective mineral prediction and assessment have been preliminarily established and put into practice with remarkable success.The main achievements presented in this thesis can be summarized as follows:1. The theoretical key of the "Three-component" mineral prediction is "seeking anomaly or / and difference". It is source of blazing new trails, basis of seeking orders, much important to the multi-objective mineral prediction and assessment Based on systematic studies of the inhomogeneity, diversity, variety, intergrowth law, multiple properties and uses of earth mineral resources, the multi-objective mineral prediction and assessment goes deeply into practice from seeking anomaly or / and difference to order or / and law of ore-forming.2. The multi-objective mineral prediction is the theoretical basis and important approach of systematic mineral prospecting. We should have a scientific outlook of earth mineral resources, and implement synthetic, systematic, entire and practical standards of mineral prediction and assessment. Also we should carry out in different prospecting stages and different scales.3. Based on the comprehensive studies of geo-anomaly, diversity of mineralization and spectrum of mineral deposit, the basic way of the regional multi-objective mineral prediction and assessment is: systematically setting up the mineral prospecting model, quantitatively delineating and optimizing the target areas of different mineral resources. In the studies of this thesis, we have quantitatively delineated and optimized ore-finding target areas in northwestern of Yunnan. There are 6 target areas of barite, 4 of Cu-Au-Mo, and 5 of Pb-Zn-Ag-Au. In addition, we have prospected 4 buried ore-bodies of Pb-Zn-Ag-Au and found 5 perspective barite ore-body areas with large- to huge-size perspective reserves.4. The multi-objective mineral prediction and assessment of ore deposit is the basis of achieving the "non-waste mining industry" or "green / clean mining industry". In this thesis, studies show that the Xigou ultrabasic rock body is a synthetic ore deposit composed of serpentinite ores, decorative stone ores, metallic and precious metallic ores. They differently occur in shallow and deep parts of the rock body. The model of "stereoscopically prospecting, systematically evaluating and synthetically exploiting" has been preliminarily established.5. The multi-objective mineral prediction and assessment of ore body is basis of studing on "comprehensive utilization" and "best utilization" of mineral resources. In this study, we have systematically studied on the diversities, variations of zeolite ores and the relationship between compositions and properties of zeolite ores in the Muling ore-deposit, preliminarily established the prospecting and evaluating geo-chemical models of different types of zeolite ore bodies. Moreover, We have found and verified one modernite ore-body and one clinoptilolite ore-body in Muling. A multi-objective exploiting and utilizing plan has been preliminarily put forward to different zeolite ore-bodies.更多还原
