槽河渡槽是南水北调中线工程河北省段最大的建筑物，河床段卵石层深厚且含砂量小，钻探取样难度极大；就漕河渡槽深厚卵石层勘探中钻具的选用、技术参数的选择及植物胶配制方法、注意事项、取芯样技术进行了较详细的叙述并进行了总结，可供以后类似地层勘探时参考。

Greywacke samples of Middle and Late Triassic collected from Hongcan well in Zoige were analyzed by ICP-MS for REE and trace elements. The result shows that these samples were originated continental crust because they enriched in Cs,Rb,Th and high REE contents and depleted in Sr,Nb and Ta. Negative Eu anomalies and strong differentiation between heavy and light REE are significant. Both the contents and ratios of the inactive trace elements and the results based on discriminant diagrams indicated that the sedimentary tectonic setting of Zoige Basin was dominated by continental island arc and the sediment in this basin was strongly affected by continental island arc between Middle and Late Triassic.
