| 摘 要： | 赋存油、气、煤和（或）铀能源矿产的沉积盆地，称为能源盆地。沉积作用及建造是影响油气煤铀同盆共存、成藏及分布的重要因素和物质基础。能源等沉积矿产及其形成，是沉积学的重要组成部分。通过讨论能源盆地沉积建造与油气煤铀赋存成藏及分布的内在联系，提出成煤建造在盆地演化和空间分布上，总体处于成油气建造和成铀建造的过渡、衔接部位和承前启后的演化阶段。并探讨了厚煤层的初始成煤物质来源与成因，蚀源区物源对盆地沉积建造、油气储层和铀成矿的重要影响。分析认为当前存在重先进技术观测测试，轻露头区精细剖析的倾向；对后期改造的影响程度和原盆古沉积面貌恢复的水平尚需重视和提高。能源盆地沉积学内涵的自然外延领域广阔，与之相关的前沿科学问题颇多。应将沉积学置于盆地形成演化和改造的时空过程中，兼顾地球环境和生物演变进程，进行整体、动态、综合研究。重点讨论了其中部分相关前沿科学问题，如:沉积盆地动力学、地球环境及生命演变对沉积和成矿作用的影响、有机与无机相互作用对能源矿产形成的影响、事件沉积学及深部作用与成矿作用的关联、能源矿产空间分区性及偏富极形成的沉积学环境、沉积建造和沉积矿产年代学等。

| Abstract: | Energy sedimentary basins refer to the sedimentary basins which can contain energy mineral deposits as oil, gas,coal and/or uranium. Sedimentation and sedimentary formation are the important factors and material basis influ-encing the occurrence,accumulation and distribution in a certain basin. The sedimentary energy deposits and the for-mation consist of the key section of sedimentology. It is discussed that the inner relations of the sedimentary formation and the occurrence,accumulation and distribution of the oil,gas,coal and uranium deposits,and proposed that the coal formation is in the transition,cohesion,and the evolutionary stage of past and future during the basin evolution and spatial distribution.It shows that the material source and origin of the initial coal-forming material of the thick coal seam,and indicates that the source area has important influence on sedimentary formation,oil and gas reservoir and uranium mineralization.Two weak points exist in energy basin′s sedimentology field.One is the inclination of emphasi-zing the advanced technology observation test and ignoring detailed analysis of outcrop area.Another is the need to pay attention to and improving the influence degree of later reformation and the restoration level of the paleo sedimentary features of the original basin. Energy basins sedimentology has broadly extensional field and various frontier scientific problems. Therefore,comprehensive,dynamic,integrated research is needed through putting the sedimentology in the space-time evolution of basin formation and reformation together with the evolution of the earth's environment and bio-logical processes. Partial relative frontier scientific problems are focused in this paper, which are dynamics of sedi-mentary basins,influence of earth's environment and biological processes to sedimentation and mineralization,organic and inorganic effects on the formation of energy minerals,event sedimentology,deep action and mineralization, spa-tial distribution of energy minerals and sedimentary environment of lack-rich-extreme rich deposit formation,sedimen-tary formation and geochronology of sedimentary minerals. |
