| 摘要: |
| 中国正处在快速工业化和经济腾飞的前夜，必须有大量各类金属矿产资源的支撵，当今国内却供给不足。供需矛盾日益尖锐，导致了对外依存度的不断增长。本文从这一前提和解决的途径出发，分析了金属矿产资源形成与聚集的深层过程和动力学响应、地壳深处金属矿产资源探查的科学依据与例证、地球物理方法和技术支撑。据此提出：①当今国家所公布的资源量系指第一深度空间（0-500m）找矿、勘探和开发的资源量，尚不能完全表征全国金属矿产资源量的全部；（多实施第二深度空间（500-2000m）金属矿产资源的找矿、勘探和开发已迫不及待；③在深部金属矿产资源的探查和开发中，必须依靠新的认识和新的理念，采用先进的、高精度的地球物理探测方法和技术，并建立起有自主特色的深部矿产资源探查理论、方法和技术体系。 |

| Abstract: |
| China is just on the eve of rapid industrializing and economic development, which must be supported by great quantities and all kinds of metallic mineral resources. At present the domestic supply is insufficient and the contradiction between supply and demand is becoming increasingly acute, thus resulting in increasing reliance on imports. Proceeding from this premise and ways of solving the problem, the paper analyzes the deep processes of formation and accumulation of metallic minerals and their dynamic response presents the scientific basis and examples, geophysical methods and technical support of metallic mineral exploration in the interior of the crust. According to these the author suggest that: 1 the present resources published by the state are those for exploration and exploitation in the first deep space (0-500 m), which cannot represent all the metallic mineral resources of the country; 2 it is very pressing to carry out metallic mineral exploration and exploitation in the second deep space (500-2000 m); and 3 we must rely on new ideas and new concepts, use advanced and highly precise geophysical exploration methods and techniques in exploration and exploitation of deep metallic mineral resources and to establish a theoretical and methodological and technological system of mineral exploration with our own characteristics. |
| Key words: formation and accumulation of metallic minerals deep processes dynamic response mineral exploration in the second deep space high-precision geophysical method and technique |
