This project is to determine the origin of magnetite deposits at El Laco, Chile through a detailed field and isotopic study. The results will be used to develop a genetic and exploration model for the origin of REE-enriched iron oxide deposits worldwide. The apparent contrast in size and tectonic setting of Proterozoic and Phanerozoic deposits of this class raises the larger issue of tectonic setting and crustal evolution in the formation of large- scale mineralizing systems, and relates this project to the fundamental question of what it is that makes a world-class ore deposit.

该项目旨在通过详细的领域和同位素研究来确定El Laco的磁铁矿沉积物的起源。 结果将用于开发一个遗传和探索模型，以用于全球富含REE的氧化铁沉积物的起源。 该类别的properokoic和Phanerogoic沉积物的大小和构造设置的明显对比，在形成大规模矿化系统的形成中引发了更大的构造环境和地壳演化的问题，并将该项目与使世界级矿石沉积物的基本问题联系起来。
