REU: ROW: Origin of Magnetite Deposits at El Laco, Chile

该项目旨在通过详细的野外和同位素研究，确定智利埃尔拉科的磁铁矿矿床的来源。这一结果将用于开发世界范围内稀土富集型氧化铁矿床的成因和勘探模型。这种类型的元古界和显生宙矿床在大小和构造环境上的明显对比，提出了大规模成矿系统形成中的构造背景和地壳演化的更大问题，并将这一项目与什么构成世界级矿床的根本问题联系在一起。

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.
