Recent research in the Yilgarn Craton and the Pilbara Craton has highlighted the importance of granitoid domes not only as a heat engine and possible fluid source for gold deposits, but also as an important controlling factor on the regional stress field and structural inventory. Because gold mineralization is largely structurally controlled, it is important to resolve the regional and local tectonic evolution of a granite-greenstone terrane, not only to understand the evolution of early Earth but also to constrain the formation and localization of major lode gold deposits. To understand the sources and pathways of fluids involved in gold mineralization it is of key importance to understand the interplay between metamorphism, magmatism and flow in the lower crust, but also the formation of early rift basins and late orogenic basins in Archean lithosphere, as all of these processes relate to different fluid reservoirs. In this project we will combine field work and 3D structural models of suitable areas in the Yilgarn Craton with a numerical modeling approach to better constrain the tectonic evolution and gold endowment of granite-greenstone terrains. The work will be carried out in collaboration between Stockholm University, the Geological Survey of Western Australia, the University of Sydney, and CSIRO Earth Sciences and Resource Engineering.
The successful candidate holds a MSc or equivalent degree in the Geological Sciences. We are seeking a highly motivated researcher with genuine interest in field geology and numerical modelling of tectonic processes.
