中文摘要
在1990年阿尔文的11次潜水中,在赫斯深渊的裂谷中暴露出来的东太平洋隆起产生的最上层洋壳的连续部分,包括枕层岩脉和岩脉-辉长岩的过渡,被勘探和取样。在9次挖泥船拖运中发现了200多个岩石样本。通过使用斯克里普斯海洋研究所的新的电感耦合等离子体质谱获得一套全面的主要氧化物、微量元素和矿物数据,初步研究将得到扩展。
英文摘要
Continuous sections of uppermost ocean crust produced at the East Pacific Rise, including the pillow-sheeted dike and dike-gabbro transitions, have been exposed by rifting in the Hess Deep were explored and sampled during 11 dives of ALVIN in 1990. Over 200 rock samples recovered in 9 dredge hauls. The preliminary studies will be extended by obtaining a comprehensive suite of major-oxide, trace-element, and mineral data using the new ICP-MS at Scripps Institution of Oceanography.
