dc.description.abstract	The Sudbury Structure (SS) is an impact crater in Northern Ontario (Canada), known for its significant concentrations of sulfide ores and the complexity of its structural setting. Even after decades of research and exploration, essential questions about its basin structural arrangement remain unresolved. One of these unsolved problems is the existence of the impact crater’s central uplift, a structure that, if recognized, might improve the understanding of the Sudbury Structure's geological history and its mineral deposit arrangement. Here, we evaluated whether the SS’s South Range could house the Structure’s central uplift. A 3D model of the SS's South Range's central zone using magnetic and structural data is presented here to evaluate the presence of the central uplift within this area. We identified a dome-shaped structure on the model's lower noritic surface, accompanied by a horizontalizing behavior on the model's upper overlaying surfaces. By comparing the observed modeled structural disposition with a conceptual model representing a present central uplift scenario, we propose the presence of this structure in the SS’s South Range's central zone. This consideration might help to clarify Sudbury Structure subsurface rocks disposition relating some of its main magnetic and structural characteristics to the final modeled surfaces' magnetic values and geometrical tendencies.
