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.

Key words: oil-gas-coal-sandstone uranium deposit, coexistence in the same basin, reservoiring/mineralization mechanism, basin dynamics, basin reservoiringing/mineralization system, Ordos basin
