    摘要:

    “找矿方式”是指技术上采用什么观点和方法手段进行找矿活动,大体上可分为“经验式”、“成因式”、“技术式”和“信息式”。经验式主要依靠直接或间接标志找矿,不太深究标志的成因;成因式则试图通过对找矿标志的成因解释以使其具有普遍意义,进而指导找矿;技术式侧重于研制某种适当的技术方法,用以寻找矿床;信息式不拘泥于上述任何一种找矿方式,而是强调借助数字化技术对各类找矿信息进行综合分析。上述各种方式均在找矿实践中发挥着作用,但也都存在着这样那样的难题。无论选择何种方式,对下述三个方面必须有清醒认识,否则可能会事与愿违甚至造成经济损失。其一,矿床成因研究探索性极强,勘查者要对研究成果客观评价并恰当应用。其二,地质找矿实践性极强,不能把一些必要的基础地质工作和经验性认识混同于矿床成因研究和成矿理论。其三,地质找矿工作是项复杂的系统工程,所选择的技术方式应该视工作进展情况和实际需要而变化。这凸现出能对各种观测资料、成因观点和技术手段作出综合评价的集成信息系统的重要作用。

    Abstract:

    The way of orefinding refers to the technical point of view and the methods to be applied to mineral exploration, which can roughly be identified as empirical, genetic, technical, and information approaches. For empirical way, ore finding relies on the direct/indirect indicators of ore without much concern about their geneses. The genetic study tries to explain the underlying mechanisms of ore formation so that they can be applied to orefinding more universally. The technical approach focuses on technical devices applicable to orefinding. The information system integrates all available geological and mineralogical data with modern digital tolls so that a more comprehensive strategy for orefinding can be achieved. All the way above have played roles in mineral exploration, although problems from each category remain to be solved. No matter what way is being chosen for ore exploration, the following three issues should be clear in mind ,otherwise things may go to the opposite of one's wishes and cause major uncertainties and economic lose. Firstly, ore genetic research is highly tentative, and its conclusions should be valued objectively and applied properly. Secondly, mineral exploration is a series of practical activities aimed at finding ores that can be developed economically. Those geological studies necessary to mineral exploration should not be viewed the same as genetic research in ore deposits, and, in the meantime, some of the empirical knowledge summarized from practices should not be confused with oreforming theories. Thirdly, mineral exploration is such a complicated systematic practice that the way of orefinding must be changed based on situation and reality, for which an integrated information system is critical to evaluate the existing data, ideas, and technical requirements.
