查询词典 sediments

Such features are typical of ancient lower continental crust, e.g., Archean granulite terranes that experienced extensive U-Th loss and developed time-integrated low radiogenic Pb compositions. The occurrence of the west Ujimqin andesites indicates the existence of ancient continental lower crust beneath the NE China fold belt.4 The Mesozoic granitoids in the Zhangguangcai Range and Jiamusi block have lower Nd ε_(Nd =-3.5～+ 2.1, T_ = 1.0～1.27Ga and highly radiogenic Pb and Sr isotopic composition ~(206Pb/~(204)Pb = 18.4～18.9,~(87)Sr/~(86)Sr = 0.705～0.711, suggesting that the pelagic sediments of the Paleo-Asian Ocean or their metamorphosed derivates were an important component in the region.5 The Pb isotope mapping results show that the mafic rocks in the northern Hinggan Mountains have higher and weakly variable ~(206)Pb/~(204)Pb ratios than those from the southern Hinggan Mountains and the Liaoyuan-Yanji area.

该套岩石的出现为证明东北地区存在古老大陆下地壳提供了重要证据。4张广才岭-佳木斯地区中生代花岗岩表现出低ε_(-3.5～+2.1)、高T_(1.0～1.27Ga)和高放射成因Sr~(87Sr/~(86)Sr=0.705～0.711和Pb同位素组成~(206Pb/~(204)Pb=18.4～18.9，反映了古亚洲洋远洋沉积物或变沉积岩为区域地壳的重要组分之一。5同位素填图结果表明，大兴安岭北区基性火山岩表现出较高且变化小的~(206)Pb/~(204)Pb比值；而南兴安岭-辽源-延吉地区中生代基性火山岩整体上表现出相对北区低~(206)Pb/~(204)Pb同位素比值特征。

developed 过去分词作后置定语：这里强调一句，如果是现在分词作后置定语，因为现在分词不可能直接跟在名词后面作谓语动词吧，除非有be动词一起表示进行时。而过去分词，如果它的过去式和过去分词形式不同，也好判断。困难主要出现在过

The Glomar Challenger定位到原文第二段第二句Using techniques first developed for the offshore oil and gas industry,the DSDP's drill ship,the Glomar Challenger,was able to maintain a steady position on the ocean's surface and drill in very deep waters extracting samples of sediments and rock from the ocean floor.

推理判断题[考频：66]。原文第二段讲述了对海底进行第一次探索的情况。对海底首次进行探索始于 1968年的深海钻井工程，而在这一工程中发挥了主要作用的正是Glomar Challenger，它能在海平面上保持稳定并且能够钻入深水中，从而抽取样本。故D正确。
