The role of passive seismology in imaging sedimentary basins
Convener: Simone Pilia | Co-conveners: Caroline Eakin, Shubham AgrawalECSECS, Nicola Piana Agostinetti
Sedimentary basins are crucial geological features. They house vast reserves of natural resources, strongly influence ground shaking during an earthquake, and provide valuable insights into Earth's subsurface dynamics. Accurately determining the geometry of these basins is fundamental for various geoscientific and economic applications, including resource exploration, seismic hazard assessment, and the comprehension of crustal tectonics. Notably, determining seismic properties in sedimentary basins is of paramount importance, as sediment-bound minerals represent a burgeoning frontier in mineral exploration.
In recent decades, passive seismology has emerged as a powerful and versatile tool for imaging sedimentary basin, offering non-invasive and cost-effective insights into subsurface structures. Numerous methodologies such as the horizontal to vertical spectral ratio, receiver function analysis, ambient noise correlation, and seismic interferometry, have been developed or adapted for the study of sedimentary basins. These methods have demonstrated remarkable success in retrieving information about the large-scale structure of sedimentary basins. Meanwhile, the growth of large nodal networks and Distributed Acoustic Sensing (DAS) offers the potential to study sedimentary basins at different scales and in new ways.
The primary objective of this session is to stimulate discussion regarding the current state of sedimentary basin imaging using passive seismic methods, with a particular emphasis on recent advancements in acquisition and processing techniques. We aim to explore the different ways in which passive seismology is enhancing our understanding of sedimentary basin architecture. Contributions that take a multidisciplinary approach are particularly welcome.
