【摘要】 沉积盆地是诸多沉积矿产成生、赋存的基本单元和成藏(矿)的大系统,具有既相对独立又统一的成藏(矿)环境和动力学背景,有其自身的成矿特点和规律,可命名为盆地成藏(矿)系统(单元)以与造山带等成矿系统相并列和区别。目前国内外的矿产勘查、开采利用和研究揭示,油、气、煤和铀主要赋存在沉积盆地中。这4种重要能源矿产同盆共存富集存在普遍、含矿层位联系密切、空间分布复杂有序、赋存环境和成藏(矿)作用有机相关、成藏(矿)-定位时期相同或相近,表明其间有着密切的内在联系和统一的地球动力学背景。在盆地演化和后期改造过程中,油、气、煤、铀等沉积矿产同盆成生共存、相互作用、各自成藏(矿)和改造定位。它们成生-成藏(矿)和定位的主要期次,与盆地演化-改造的阶段及主要地质事件有明显的响应联系和密切的耦合关系。文中讨论了其中部分相关前沿科学问题,初步建立了鄂尔多斯盆地演化-改造阶段及其主要地质事件与油、气、煤、铀成藏(矿)作用期次的时序对应关系。更多还原

【Abstract】 Sedimentary basin is the basic unit of the generation and occurrence of various sedimentary mineral deposits,and is also a large reservoiring/mineralization system.It has both relatively independent and unified mineralization environments and dynamic settings,and has its own mineralization characteristics and patterns.It can be named as basin reservoioring/mineralization system/unit,for differentiating from the other mineralization systems,such as orogen mineralization system.Recent mineral exploration,exploitation and research both at home and abroad show that oil,gas,coal and uranium deposits mainly occur in sedimentary basins.These four major mineral deposits commonly coexist and get enriched in the same basin.Their producing formations are closely related and their space distributions are complicated but ordered.The environments of their occurrences are intrinsically related,with reservoiring/mineralization processes and the time of reservoiring/mineralization and finalization to be the same or similar.All these features indicate that they have close intrinsic relationships and a unified geodynamic setting.The sedimentary minerals,such as oil,gas,coal and uranium,are generated and coexist in the same basin,interact with each other and separately accumulate and are finally allocated through reformation in the process of basin evolution.The main times and stages of generation-reservoiring/mineralization have evident responsive relations and close coupling relations with the main geologic events and basin evolution and reformation stages.This paper discusses some relevant frontier scientific issues and preliminarily establishes the chronogenesis and corresponding relationships between basin’s evolution-reformation stages and major geologic events and the reservoiring/mineralization of oil,gas,coal and uranium deposits.更多还原
