This project involves the systematic collection and analysis of rock samples form near-ridge seamounts on the pacific plate within 150 KM of the East Pacific Rise axis between 16 and 19 S. Rock, natural glass, and constituent minerals will be analyzed using electron probe, wavelength-dispersive X-ray fluorescence, and mass spectrometer techniques. These data, in conjunction with existing geochemical data on the nearby East Pacific Rise axis, will form the basis of a 3-D analysis of the upwelling zone associated with this fast-spreading extreme of ocean ridge accretion.

该项目涉及系统收集和分析 岩石样本形成太平洋板块上的近洋脊海山， 东太平洋海隆轴在南纬16度和19度之间的150公里。 岩石， 天然玻璃和组成矿物将使用 电子探针、波长色散X射线荧光和质谱 光谱仪技术 这些数据与现有的 东太平洋海隆轴附近的地球化学数据，将形成 上升流区三维分析的基础， 这片快速扩张的海脊增生带
