SIT4ME project carried out its first 3D seismic survey in Spain, in the province of Huelva. The field data acquisition campaign started at the beginning of October and was completed in three weeks.
The study area was the mining zone known as Elvira-Sotiel, near the towns of Valverde del Camino and Zalamea la Real, in the eastern shore of the Odiel river, in southern Spain.
The campaign staff was made up of around a dozen researchers and technicians of the SIT4ME project partners: Institute of Earth Sciences Jaume Almera (ICTJA-CSIC), TU Bergakademie Freiberg (TUBF) and Uppsala University.
Almost one thousand seismic stations were deployed during this fieldwork, which main goal was to acquire data to perform a 3D seismic profile of the subsurface that can be used as a mineral exploration solution.
Two different types of seismic signal sources were used during this survey: seismic noise and controlled source. The stations were deployed irregularly on the study area to record the seismic noise of the zone.
This data will be used later to analyse the resolution capacity of the images obtained through technologies based on seismic noise interpherometry.
In addition, the team used also a vibroseis truck from the TUBF as a controlled seismic source of the signal to be recorded by the stations which were already set in the area to record the seismic noise. The data obtained from this source will be compared later with the other registered data to verify the new imaging technology that the project aims to develop.
