9314711 Froelich Funds are recommended for this project to test the concepts of mineralogical and fluid chemical evolution of a deep sea site on a subduction zone at the Chile Triple Junction. Pore Fluids will be analyses for Rb, Cs, Ba, Ni, Cr, rare earth elements, and U, O, Sr and He isotopes. These data will show whether a collisional phase of hydrothermal or metamorphosed fluids produced the observed mineralogical sequence and fluid chemistry 100 k.y. ago.

建议为该项目提供9314711弗罗里希基金，以测试智利三交界处俯冲带深海地点的矿物学和流体化学演化概念。将对孔隙流体进行Rb、Cs、Ba、Ni、Cr、稀土元素以及U、O、Sr和He同位素的分析。这些数据将显示热液或变质流体的碰撞相是否产生了所观察到的矿物学序列和流体化学100K.Y。那是以前的事了。
