Abstract

Deep-seismic reflection data across the Eastern Goldfields Province, northeastern Yilgarn Craton, Western Australia have provided information on the regions crustal architecture and on several of its highly mineralised regions. The 2001 Northeastern Yilgarn Deep Seismic Rflection Survey data has imaged several prominent crustal scaled features, including an eastward thickening of the crust across the northeastern Yilgarn Craton, the subdivision of the crust into three broad layers, the presence of a prominent east dip to the majority of the reflections and the interpretation of three east-dipping crustal-penetrating shear zones. These three east-dipping shear zones are major structures that subdivide the region into four terranes.

Lineage

The granite-greenstone terrains of the Eastern Goldfields Province, Yilgarn Craton, contain numerous world-class gold deposits that are spatially associated with major structures. The three-dimensional geometry of these major structures reveals information on the size and architecture of the gold mineralising systems and the geodynamic processes responsible for their generation. Our current knowledge of the three-dimensional nature of the Eastern Goldfields Province is largely restricted to the Kalgoorlie region, where the collection of deep seismic profiles has allowed the development of detailed 3D geological maps (Goleby et al., 2002). Along with previous seismic interpretations (e.g. Drummond et al., 2000), these 3D maps define the geometry of the major structures and show that the greenstone succession is 5-7 km thick and controlled by interlinked crustal shears that compartmentalise the granitegreenstone succession into distinct domains. To follow up, a further deep seismic reflection survey was proposed to acquire additional seismic data within other areas of the Eastern Yilgarn Craton to examine the geometry of additional major structures and to enhance our understanding of the 3D structure over a wider area.
