The relative roles of tectonism, metamorphism and hypogene processes in the enrichment of banded iron-formations
Enriched iron ore bodies within banded iron-formations (BIFs) represent the largest and most concentrated known accumulations of iron. Thus, understanding the evolutionary history of these resources has immense significance to the future of the steel industry worldwide. Llyam White's PhD project aims to determine the timing of enrichment, and to distinguish the different geochemical conditions necessary for the generation of highly enriched ores. Enriched iron ores are known to exist in somewhat structurally complex areas. Thus, understanding the structural evolution of these deposits has the potential to facilitate further exploration in areas sharing a similar structural history. The combined field and micro-analytical study proposed here will promote significant advances in the exploration for enriched iron ore bodies still awaiting discovery.
