L154 North Yilgarn Seismic Survey, WA, 2001. Stacked and migrated seismic data and images for lines 01AGSNY1, 01AGSNY2, 01AGSNY3 and 01AGSNY4.

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. Raw data for this survey are available on request from clientservices@ga.gov.au
