| 摘 要： | 重矿物资料在沉积物物源分析中被广泛的应用。采用聚类分析的数学统计方法,将重矿物资料在垂向上分出不同的沉积期次,得出表征不同母岩区的重矿物组合类型,进而在整个研究区对比划分物源体系并结合ZTR等值线图研究各沉积期次物源方向。由此涠西南凹陷古近系流三段下亚段可划分为四大物源体系,分别为北西物源体系,南西物源体系,北东物源体...

| Abstract: | Heavy mineral data are widely used in the analysis of sediment source.Source rocks of different depositional stages and different source areas can be identified based on heavy mineral suites.In this study using Q-type clustering analysis,the sample group with the same or similar features in the vertical profile is identified as sediments of the same depositional stages,so each sample group is representative of a certain depositional stage or source rock.On the basis of Q-type clustering analysis,using R-typ... |
