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.

9303524 Langmuir这是一艘从南纬35度至56度之间的太平洋-南极东太平洋隆起2200公里长的区域中挖掘火成岩样本的游轮。这项工作将为沿直脊段的喷发岩石与在转换断层底板上构造的相邻上冲脊和在同一转换域中孤立的转换内扩展段获得的喷发岩石提供系统的岩石学比较。这项工作还将提供一个以前没有样本的地区的样本。
