中文摘要
9303524朗缪尔这是一艘邮轮,从太平洋-南极东太平洋隆起南纬35度至56度之间长达2,200公里的地段挖掘火成岩样本。这项工作将对沿直脊段喷发的岩石与从建造在转换断层底板上的毗邻过冲山脊获得的岩石以及从同一转换域中孤立的转换内扩展段获得的岩石进行系统的岩石学比较。这项工作还将提供来自以前没有样本的地区的样本。
英文摘要
9303524 Langmuir This is a cruise to dredge igneous rock samples from a 2200-km long section of the Pacific-Antarctic East Pacific Rise between 35 and 56 degrees south. The work will provide a systematic petrologic comparison between eruptive rocks along straight ridge segments and those obtained both from adjoining overshot ridges constructed on the floors of transform faults and from isolated intra-transform spreading segments in the same transform domains. The work will also provide samples from a region that has not previously been samples.
