Constructing a Comprehensive Seismological Model of the EPR near the MELT Experiment

摘要本项目是对南纬17度东太平洋地幔电磁层析成像（MELT）实验地震资料进行的第二代分析和建模。分析的目的是建立一个基于地幔流动和熔体生成模型的综合模型，该模型同时满足所有不同类型的地震数据。分析将分为四个阶段；分析尚未开发的地震数据和波形信息，共同反演所有地震学约束条件，以找到一个三维的、自洽的模型，基于物理原理和对流态的猜测测试三维各向异性正演模型，并结合其他约束条件，包括与电磁数据建模团队共同解释。

ABSTRACTThis project is the second generation analysis and modeling of seismological data from the Mantle Electromagnetic and Tomography (MELT) experiment conducted on the East Pacific Rist at 17 degrees South. The goal of this analysis is to develop a comprehensivew model based on models of mantle flow and melt generation that satisfies all the different types of seismological data simultaneously. There wil be four phases of analysis; analyzing seismic data and waveform information that have not yet been exploited, inverting all the seismological constraints jointly to find a three-dimensional, self-consistent model, testing 3-D anisotropic forward models based on physical principles and guesses about the flow pattern, and incorporaing other constraints, including working toward a joint interpretation with the team of modelers of the electromagnetic data.
