我国砂岩型铀矿“断隆成矿观点”的提出与应用分析——将遥感应用“从技术层面提升到科学层面”的探索
|
摘要
本文对鄂尔多斯盆地和塔里木盆地铀矿床(含矿化集中区)进行了遥感研究,发现其成矿环境与断块隆起(断隆构造)密切相关。鉴此,与重力、航磁、航放、地震探矿等物化探信息和现代信息技术(G IS技术、三维可视化技术、计算机模拟技术)结合,注入铀矿地质专业知识,使信息转化为新的认识,提出了中国克拉通盆地铀矿"断块成矿的理论"和"断隆成矿的观点",并强调围绕断隆构造及其边缘是这类盆地区域找矿的主要方向。通过上述研究,探索了陈述彭院士倡导的将遥感应用从"技术层面提升到科学层面"的理念。这一理念指明了遥感技术深度开发与深化应用的方向。实践表明,首先,充分利用遥感技术的优势,发现问题,提出问题,然后,通过信息综合和技术集成,对遥感的发现进行延伸研究,并注入专业知识,使数字和信息转化为创新知识,来指导实践和决策。这是将遥感应用从"技术层面提升到科学层面"的重要途径。
Through remote sensing research of uranium deposit in Ordos and Tarim basins,the close relationship of its metallogenic environment and fault-block uplift(fault-uplift structure) was found.Based on this discovery,and combined with modern information technology(GIS,3d visualization,computer simulation,etc.) and geophysical and geochemical information such as gravity,aeromagnetic,airborne radiometric survey and earthquake prospecting,then adding in uranium geology professional knowledge,the information transform was made into new cognition,and finally,a viewpoint of fault-uplift mineralization and the theory of fault-block mineralization in Craton basin of China were put forward.To encircle the fault-uplift structure and its brink is the main direction of prospecting in this type of basin.So,the conception of putting the application of remote sensing "from the technical aspect to scientific aspect",which,was advocated by the late academician Chen Shupeng,was explored.This concept designated the direction of deep development and further application of remote sensing technology.The practice shows that it is an important approach to make full use of the advantages of remote sensing technology at first,to discover and put forward problems,then to use comprehensive information and integration technology,to make extension study of the remote sensing discovery and combine with professional knowledge,to make the data and information transform into innovation cognition,and finally to direct the practice and decision-making.
