Resumen

The need to satisfy the increasing demand for raw materials in a safe, sustainable and cost-effective manner, is the main moti- vation of the SIT4ME project, financed by the EIT-Raw Materials program. The main objective of SIT4ME is to develop an effective and efficient methodology to apply seismic techniques in the search of mineral resources. This project focuses on the acquisition, processing and interpretation of seismic data (controlled and natural sources) in a real environment: Sotiel-Co- ronada, located at the SW of the Iberian Pyrite Belt. These data will allow us to obtain images of the principal structures and mineralized levels at depths of 300-500 m. The 2D seismic data process flow includes static corrections, deconvolution, amplitude equalization, frequency filters and velocity analysis. The correlation between seismic images, surface geology and existing drill cores allowed identifying the main deep structures. The results show good, north-dipping reflectivity up to 2000 ms TWT. A high reflectivity zone, c. 380m long, exists in the center of the profile at 130 ms TWT, related to one of the mineralized areas. Future work will include the pre-stack depth migration, processing of 3D seismic data and first arrivals tomography to obtain a robust model that increases the probability of success in the exploration.
