COEXISTENCE AND ENRICHMENT OF OIL,GAS,COAL AND URANIUM IN A BASIN AND THEIR ORGANIC MATERIAL BASE

Ordos basin accumulates various energy resources.Taking the oil,gas, coal and uranium in the basin as subjects,the scientists of China's State "973" multi-energy minerals enrichment project study the scientific issues of interest concerning the coexistence and accumulation of energy minerals in one basin,such as the material base and geodynamical setting,the accumulation(or mineralization) mechanism and enrichment environment,and the temporal and space distribution and control factors.This interdisciplinary study provides a new perspective on comprehensively understanding energy geosciences.Through reviewing foreign literature and discussing the macroscopic relationship and the macro-organic material base of oil,gas,coal and uranium coexisting and accumulating in the same basin,the paper is expected to benefit the research.
