Towards adapting reverse vertical seismic profiling for ambient-noise imaging with transient sources
Automatic estimation of stationary-phase receivers for improved retrieval of the interferometric Green's function
Most of the ambient-noise studies are performed with sensor arrays located at the surface. Passive recordings containing seismic arrivals from subsurface sources could be seen as having a geometry resembling reverse vertical seismic profiling (RVSP). In such scenarios, the int ...
Reflection imaging of complex geology in a crystalline environment using virtual-source seismology
Case study from the Kylylahti polymetallic mine, Finland
Seismic interferometry for mineral exploration
Passive seismic experiment over kylylahti mine area, Finland
Despite the unrivalled spatial resolution and depth penetration of active-source seismic methods used for mineral exploration in hardrock environment, economic and environmental restrictions (e.g., source permitting) may preclude its full-scale application. In such a case, 2D ...
The main issues related to passive-source reflection imaging with seismic interferometry (SI) are inadequate acquisition parameters for sufficient spatial wavefield sampling and vulnerability of surface arrays to the dominant influence of the omnipresent surface-wave sources. ...
We apply a full-scale 3D seismic virtual-source survey (VSS) for the purpose of near-mine mineral exploration in the Kylylahti sulfide deposit, Finland. Based on the ambient-noise (AN) characterization including beamforming results, we created a 10-days subset of AN recordings ...
