The project aims to understand the geological controls on high-grade(>65wt%Fe)iron ore deposits of the Hamersley Province. In particular, the role of hydrothermal fluids in the transformation of banded iron formation (BIF) to high-grade iron ore. Three deposits (Mt Tom Price, Paraburdoo and Channar) provide an ideal study of the relationship between the structural evolution, timing, and characteristics of hydrothermal and supergene processes. In particular, the the study aims to investigate the structural control and fluid chemistry of the hydrothermal system. The outcomes of this study will include a better understanding about the timing and fluid characteristcs of hydrothermal/supergene events and their significance to the formation and geometry of high-grade iron ore deposits in the Hamersley Province.

该项目旨在了解哈默斯利省高品位（>65wt%Fe）铁矿床的地质控制。 特别是热液流体在条带状铁建造（BIF）转化为高品位铁矿石中的作用。 三个矿床（Mt Tom Price、Paraburdoo和Mt Pastar）为研究构造演化、时间和热液与表生作用特征之间的关系提供了理想的研究。 特别是，该研究旨在研究热液系统的构造控制和流体化学。 本研究的成果将包括更好地了解热液/表生事件的时间和流体特征及其对哈默斯利省高品位铁矿床的形成和几何形状的意义。
