该奖项将支持一个项目的最后一年,该项目旨在建立流体和矿物机制、流体循环途径和时间尺度,这些机制与智利三重交界处形成的自生矿物的形成有关。埋藏脊系统的热液脉冲产生了一系列矿物相,除了已经完成的一系列其他分析外,还将使用Li, B和O同位素对其进行分析。将利用局部构造和运动学约束建立水文地球化学模型,以估计与脊俯冲有关的流体和地球化学通量。
英文摘要
This award will support the final year of a project to establish the fluid and mineral mechanisms, fluid circulation pathways and time scales responsible for the formation of authigenic minerals formed at the Chile Triple Junction. Hydrothermal pulses from the buried ridge system have produced a series of mineral facies, which will be analyzed with Li, B and O isotopes in addition to a range of other analyses already accomplished. A hydrogeochemical model will be constructed using local tectonic and kinematic constraints, in order to estimate fluid and geochemical fluxes associated with ridge subduction.
