| 摘 要： | 大型超大型矿床在其时空分布、控矿因素、形成机制、成矿模式诸方面与一般中小型矿床有相似甚至雷同之处,也有其特殊、独特方面,研究预测大型超大型矿床相当复杂,需要从不同学科、不同侧面、不同角度、不同途径、不同方法及不同思路进行综合研究。本文给出大型超大型矿床预测的综合信息方法,认为地质地球物理地球化学多学科综合分析是今后找矿的最主要途径。通过对大型、超大型矿床的趋群性特点分析,给出了矿床密集区的概念以及圈定的基本原则和边界条件。通过对大型超大型矿床发现途径的分析,指出大型超大型矿床的分布具有可预测性。并表述了综合信息预测方法流程,以矿床密集区为模型单元,以异常密集区为预测单元,通过地质、地球物理、地球化学等综合信息控矿地质变量的提取和合理赋值,加上数理统计方法的合理应用,达到对大型超大型矿床的预测目的。 |

| Abstract: | Researching for the super-large ore deposits (SOD) is considered a complicated problem. The SOD not only has the similar and even the same aspects in spatial-temporal distribution, ore controlling factors, metallogenic mechanism and metallogenic models, as the other common large, medium and small ore deposits, but has the special aspects for itself. It is necessary to study the SOD synthetically with different subjects, aspects , methods , ways and so on. According to the phenomenons of "Cranes stand in the chickens' folk" for the large and super-large ore deposits, the concentrated area and its basic division rules are proposed in the paper. The scope of remanent abnormal metallogenic elements and abnormal catch-basin and deep structure must be thought about during dividing the concentrated area's boundary, after studying the ore deposits distribution rules. Basing developing exploration engineering, it is discussed in the paper that the large and super-large ore deposits can be forecast, by summarizing the found ways of large and super-large ore deposits, such as finding the other ore deposits in the depth and outside of the old and known ore deposit, finding the large and super-large ore deposits by applying geochemistry methods, in the concentrated areas of medium and small ore deposits, with the metallogenic theories and models instruction, analyzing synthetic information synthetically and so on. In the paper, the ore deposits concentrated area and abnormal concentrated area are regarded respectively as the modeling and forecasting sector, in order to forecast the large and super-large ore deposits, through abstracting and evaluating the geology, geophysics, geochemistry, remote sensor and the other synthetic ore control factors, using mathematical statistics methods reasonably. |
