ABSTRACT
In modeling the geodynamic evolution of economic deposits, our aim is to adopt an holistic view of the crastal scale ore forming system with the goal of constraining the critical factors responsible for ore mineralisation and, in particular, those factors responsible for localising high grade, high quality deposits. A number of ore-forming processes are unique to areas such as the Yilgam or Mary Kathleen, and the goal in this paper is to show how FLAC can be used to assist in thought experiments that greatly improve our understanding of such processes. Surprising results often ensue, and examples are given whereby the modeling opens up new possibilities for ore genesis or regional fluid flow, not previously considered by geologists.
