9811483 Carbotte This project will continue anaylsis of multichannel seismic data collected in 1995 along two contrasting segments of the East Pacific Rise at 16 degrees north. The data set is of very high quality and is suited for further study. Questions to be addressed include: How does the physical state of the magma lens vary with the tectonic and magmatic segmentation of the ridge? Are discrete magma lenses associated with the segmentation of the summit caldera? How does the layer 2A/2B transition zone evolve and what are the implications for the geological significance of this layer and for accretion processes?

小行星9811483 该项目将继续分析1995年收集的多道地震数据 沿着东太平洋海隆的两个截然不同的部分在北纬16度。 的 数据集的质量非常高，适合进一步研究。 疑问待 解决的问题包括：岩浆透镜的物理状态如何随温度变化而变化？ 构造和岩浆的分割脊？ 是离散的岩浆透镜体 与山顶破火山口的分割有关吗 图层如何 2A/2B过渡带的演化及其对地质的影响 这一层和吸积过程的重要性？
