| 中文摘要:金属成矿省等级体制成矿研究保证程度与技术-经济条件研究保证程度双因素控制的和对其保证程度相对优选的合理区域，是深化认识矿产勘查-开发客观规律和合理进行评价的新发展，也是把以往仅按在一定地质构造背景基础上，研究不同类型矿床特征及其勘查类型的传统方法，变革为按“景、场、相、床”4个等级体制成矿序次及其随成矿史演化进程的耦合程度，以及有机地结合经济-技术条件进行勘查评价的新方法。重点阐述了等级体制成矿概念的形成、意义和研究内容，提出了地质、技术经济和合理投资的矿产勘查评价三原则，建立了以保证等级体制成矿研究程度和技术-经济条件研究程度双因素控制，以及研究程度相对合理优选区域的矿产勘查模型。 |

| Abstract:Hierarchy systematic metallogeny in a metallogenetic province is based on the principle that a coupling regularity of metallogeny is formed by a dynamic ore-forming process of four metallogenetic levels of " tectonic setting" ," metallotect convergence" ," metallogenetic phase" , and " ore deposits" through geological time in a metallogenetic province. The concept of hierarchy systematic metallogeny in a metallogenetic province has been proposed which aims at deepening the cognition for evolution of metallogenetic province through geological time and developing the reasonable assessment of mineral exploration. It also greatly reforms the conventional assessment method of mineral exploration based only on delineating the temporal and spatial distribution of different types of ore deposits in a certain tectonic setting. This paper has elucidated the formation of hierarchy systematic metallogeny as well as its geological significance and research contents , proposed three principles of geological economic technique and reasonable investment for assessment of mineral exploration, established a conceptual exploration model according to the double controlling factors both of the research extent of hierarchy systematic metallogeny and of the economic technique condition , and also set up a " reasonable assessed area" of relativity and optimization of exploration stage with economic investments . |
