The overarching objective of my research program for the next five years is to gain a better understanding of the geologic processes that lead to the formation of what are commonly referred to as economic grade iron oxide apatite (IOA) deposits. This includes the initial emplacement and crystallization, the subsequent metasomatic alteration of the host rocks, the mineralization, and any post mineralization alteration. These deposits are a major source of iron from many well-known localities around the world. There are at least two major unresolved issues with our current understanding of IOA deposits.

未来五年我研究计划的总体目标是更好地了解导致形成通常称为经济氧化铁磷灰石（IOA）沉积物的地质过程。这包括最初的扩增和结晶，寄主岩石的随后变质，矿化和任何矿化后改变。这些沉积物是来自世界许多著名地区的铁的主要来源。我们目前对IOA存款的理解至少有两个未解决的问题。
