Igneous Petrology of Upper Crustal Sections of the East Pacific Rise at Hess Deep

东部形成的最上层洋壳的连续部分 太平洋隆起，包括枕席状岩墙和岩墙辉长岩 在赫斯深渊的裂谷作用下暴露出来的 在1990年ALVIN号的11次潜水中进行了探索和取样。 200多 在9次挖掘中回收了岩石样本。 初步研究 将通过获得一套全面的主要氧化物， 在斯克里普斯使用新的ICP-MS的微量元素和矿物数据 海洋学研究所。

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.
