Abstract
Geological regions with abnormally high endowment in metals appear to have resulted from the fortunate juxtaposition in space and time of numerous, possibly exceptional, processes. The gold mineral system of the Eastern Goldfields Superterrane (EGST) is an example. In order to understand why this is so, we have taken an approach that considers the mineral system as a series of integrated components known as the Five Questions: viz 1) geodynamics; 2) architecture; 3) sources & reservoirs; 4) drivers & pathways; and, 5) depositional mechanisms. In order to better understand these components and the geological processes that define them, a range of scales needs to be considered. However at each scale the relative benefits of considering any one of the five components varies. Ultimately the aim is to use this scale-integrated process-based understanding for prediction. Understanding why a region is particularly endowed or a deposit so rich is important but only half the question. The other half is where is the next favourable region and/or camp and deposit? In this regard, we 'Answer' the Five Questions.
