中文摘要：

南水北调（中线）安阳主干渠段施工过程中开挖出大量成熟度低且受近源构造影响较大的河湖相沉积岩。对现场采集的上第三系岩石样品开展了化学成分、岩石骨架成分测试。利用Dickinson法和化学指标法，研究得到安阳主干渠段西部物源区属于被动陆缘，在上新世晚期向活动陆缘变化的认识。同期构造活动强烈的克什米尔N—J引水隧洞段的沉积岩，属于岛弧和活动陆缘的大地构造背景。本文结果丰富了构造稳定和活跃区新近纪沉积构造背景认识，可为喜马拉雅运动以来不同构造活动背景下的岩石组分和化学指标特征提供参考。

英文摘要：

Middle Route of South-to-North Water Diversion Project provides a big and ideal ＂geological trench＂ to reveal the Tertiary strata along the east piedmont of Taihang Mountain. The Neogene strata are made of the fluvial and lacustrine sediments, which are in low maturity and greatly influenced by regional tectonic activities. In this paper, the author applies Dickinson and geochemistry indicators to compare sedimentary petrology and geochemistry characteristics of Anyang main canal section with that of the Pakistani Kashmir N-J diversion tunnel. The results suggest that the Anyang main canal section belongs to passive continental margin and developed to active continental margin in Late Pliocene, while Pakistani Kashmir N-J diversion tunnel belongs to tectonic features of island arc and active continental margin. It is found that the Anyang main canal section and the Pakistani Kashmir N-J diversion tunnel, which developed under different Neogene tectonic activity settings, differ significantly in the rock components and chemical characteristics.
