| 摘 要： | 泌阳凹陷是南襄盆地中的一个次级凹陷。在核桃园组沉积时期存在3个主要物源区。根据砂砾岩的成分、碎屑重矿物组合等资料综合分析研究表明核三下亚段沉积时期3个主要物源区的母岩性质以变质岩和花岗岩为主,其次为沉积岩。但不同物源区和同一物源区不同沉积时期的母岩类型组合有所差异。物源区母岩性质的研究对研究砂体储集性能以及沉积相类型具有十分重要的意义。

| Abstract: | Most of material of the Hetaoyuan formation were derived from three provenances.The study of composition of sandstone and conglomerate and heavy minerals indicates that parent rock in the provenances was composed of metamorphic rock and granite as well as sedimentary rock.They are of great importance to sedimentary type and reservoir character of the sand bodies. |
