【摘要】 层序地层学是在地震地层学基础上发展起来的一门新兴学科,在油气等沉积矿产勘探中得到了广泛应用,并取得了丰硕的成果,但在砂岩型铀矿勘查中的应用却刚刚起步。本文总结了近年来层序地层学研究在砂岩型铀矿勘查中取得的成果,分析了层序研究中存在的问题及产生的原因,并根据砂岩型铀矿成矿特征和层序地层学发展情况展望了其应用前景,明确了层序地层学的具体应用方向,提出了具体工作建议。更多还原

【Abstract】 Sequence stratigraphy is a newly developed subject based on seismostratigraphy,and has been widely applied in the exploration of hydrocarbon and other sedimentogenic mineral deposits and great achievements have been obtained.However,the application of sequence stratigraphy to the exploration of sandstone-hosted uranium deposits is just at the beginning.In this paper,some primary research achievements of sequence stratigraphy to the exploration of sandstone-hosted uranium deposits are summarized,and problems and their reasons of the application of sequence stratigraphy are discussed.Further more,according to characteristics of sandstone-hosted uranium deposits and the development of sequence stratigraphy,the application vistas of sequence stratigraphy to the exploration of sandstone-hosted uranium deposits are estimated.Finally,application directions are proposed,and some specific suggestions are given.更多还原
