Mantle Flow Models for Melt Extraction at the Incipient Rift at 2 deg 40 N, East of the East Pacific Rise

这一奖项是对E.Klein和D.Smith(0099154)资助的一个实地项目的附加项目，该项目旨在调查位于北纬2度40‘的东太平洋隆起东侧的早期裂谷。这个初生的裂谷是火山活动的，可能提供了一个独特的机会，可以随着距离轴线的增加而采样EPR下的熔融制度。该附加模块将对上升流和熔融再结晶进行理论模拟，以便更好地了解熔体在EPR过程中的产生和迁移。PI将与M.Spiegelman合作修改现有的2D地幔流动和熔融模型，以包括早期的裂谷。之后，将开发3D模型，并针对地球化学数据进行测试。

This award is for an add-on to a funded field program to investigate the incipient rift located on the east side of the East Pacific Rise at 2 degrees 40'N by E. Klein and D. Smith (0099154). This incipient rift is volcanically active and may provide the unique opportunity of sampling the melting regime under the EPR with increasing distance from the axis. This add-on would carry out theoretical modeling of the upwelling and melting reime in order to improve understanding of the melt production and migration bvelow the EPR. The PI will work with M. Spiegelman to modify existing 2D mantle flow and melt models to include the incipient rift. After that, 3D models will be developed and tested against geochemical data.
