项目摘要
The purpose of this research is to quantify a mechanism for lateral melt migration beneath mid.ocean ridges; namely freezing induced melt channeling. Preliminary results suggest that rapid freezing near the sloping base of the lithosphere may lead to the fromation of high permeability m lt channels that allow melt to migrate to the ridge axis. The questions remaining are: (1) What are the fundamental parameters that control the process? (2) Are channels expected in the earth? (3) What is the efficiency of this process? (4) What are the observable consequences for volume timing and chemistry of mid.ocean ridge volcanism? By combining high resolution 2.D magma migration code with large scale thermal and mantle flow models, a systematic series of problems will be investigated to address these questions.
这项研究的目的是量化一种机制, 大洋中脊下的横向融化迁移;即冻结 诱导熔体沟道 初步结果表明, 岩石圈倾斜底部附近的冻结可能导致 形成高渗透性MLT通道, 迁移到脊轴。 剩下的问题是:(1)什么 是控制这个过程的基本参数吗(2)是 在地球上预期的渠道?(3)什么是效率 这个过程?(4)对成交量有什么明显的影响 大洋中脊火山活动的时间和化学成分? 通过组合 高分辨率二维岩浆运移大尺度热模拟 和地幔流模型,一系列系统的问题将是 调查这些问题。
