9300275 Castillo 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.

9300275 Castillo这是一条巡游，可将太平洋 - 南极 - 东太平洋2200公里长的岩石岩石样品挖掘出来，向南35至56度。这项工作将提供沿直脊段的爆发岩石之间的系统性比较，以及从相邻的变换断层地板上构建的隔着山脊以及来自相同转换域中孤立的转变内扩散段所获得的。这项工作还将提供以前从未有样本的区域的样本。
