摘要: 以大型隐伏矿床的发现历史为依据,系统地总结了隐伏矿勘查的经验与策略,并从矿产勘查哲学的角度进行了深入的思考。针对拟寻矿床的地质特征,抓住深部关键的地质因素,查明地球物理和地球化学特征与它们的对应关系,把地球物理和地球化学判据转化成找矿标志,是提高隐伏矿找矿效率的关键。成矿作用的分带现象是一个普遍的规律,对于指导隐伏矿预测和矿床深部勘探具有重要的意义。直接信息是矿产勘查最可靠的信息。直接信息和间接信息并不是以学科划分的,在一定的条件下和一定的研究程度上两者可以转化。以直接信息为先导,实现从区域到局部的转变,使找矿迅速突破。必须充分重视各类方法的应用条件与前提,重视各种直接信息的挖掘与印证,加强各类方法的集成与综合。对于一个重要的成矿区(带)来说,随着地质研究与找矿工作的深入,需要不断地修订和调整勘查准则。矿产勘查投资是一种高风险、高效益的投资,是一项创造性很强的实践,集调查与研究于一体。矿产勘查不以研究 “水平”论高低,而以“成败”论英雄;要看勘查的实效,而非理论的高深;要看是否见矿,而非勘查过程的简繁。经验与理论、科学与技术的交叉与融合是通向矿产勘查的成功之路。Abstract: Based on the discovery history of large buried deposits, the authors summarize the experience and strategies in buried deposit prospecting and deliberate on them in the context of the mineral exploration philosophy. To improve the efficiency and effectiveness of prospecting for deep-seated buried deposits, the key geological factors at depths related to the geological characteristics of the prospecting deposits are illustrated by their corresponding relations to the geophysical and geochemical indicators, and the geophysical and geochemical criteria for ore deposits can be transformed into prospecting indicators. The direct information is the most reliable information of mineral exploration. Direct information is the most reliable information for mineral exploration. Direct information and indirect information are not distinguished according to disciplines, and the two kinds of information may be transformed mutually under certain conditions and on degrees of survey. Direct information is used as a guide to achieve transformation from the whole region to local areas step by step until a breakthrough in mineral exploration can be made rapidly. It is necessary to pay full attention to the application conditions and preconditions of various methods and attach importance to the extraction and confirmation of various kinds of direct information and strengthening the integration of diversified methods. For an important metallogenic province (belt), the exploration criteria need to be revised and adjusted constantly when geological research and prospecting deepen. Mineral exploration is an investment with both high risk and great benefits, also a highly creative practice which combines investigation with research. The success in mineral exploration is not judged by the “level” of research and the profundity of metallogenic theory or the simplicity or complexity and the exploration process, but by the actual results of exploration and whether new deposits are found. Integration between experience and theory and between science and techniques leads to the road to the success in mineral exploration.
