中文摘要
该项目将继续对从奥罗斯科和里维拉转换断层之间的东太平洋海隆采集的样品进行岩石学和地球化学分析。 关于是否存在一个热点,为洋中脊的这一部分提供岩浆,这一问题需要更详细的分析,并对离轴较老地壳的样本进行分析。 此外,从迄今为止的工作中发现了新的问题,这些问题将得到解决。
英文摘要
This project will continue petrological and geochemical analyses of samples recovered from the East Pacific Rise between the Orozco and Rivera transform faults. The question of the existence of a hotspot contributing magmas to this section of mid-ocean ridge requires more detailed analyses and analyses of samples from older crust off-axis. In addition, new questions have been identified from the work to date, and these questions will be addressed.
