These data sets are associated with an article that is currently under review.-- Estos conjuntos de datos están asociados a un artículo que está actualmente en proceso de revisión, A new code for anisotropic traveltime tomography is presented. We describe the equations governing the anisotropic ray propagation algorithm and the modified inversion solver. This code can provide better understanding of the Earth's subsurface in the rather common geological contexts in which seismic velocity displays a weak dependency on the polar angle of ray propagation. We study the sensitivity of two medium parametrizations and compare four inversion strategies on a canonical model.

The data acquisition contract was funded by the "Programa estatal de fomento de la investigación científica y técnica de excelencia-subprograma estatal de generación de conocimiento" of the Ministry of economy and competitiveness and took place in 2015. Seismic data was successfully collected in Alhama de Murcia (Spain). The total amount of seismic reflection data collected was 13.2 km in 6 profiles NW-SE oriented. Technical specifications of the profiles: Receiver number: 240, Receiver interval: 2 m, Source: accelerated weightdrop 250 kg, Source interval: 6 m, Sample rate: 1 ms, Record time: 4 s. Contact people: Martínez-Díaz, J.; jmdiaz@geo.ucm.es and Carbonell, R.; rcarbo@ictja.csic.es, This work is part of the research project: “InterGeo”. One of the main objectives of this project is to understand the seismogenetic behavior of the Alhama de Murcia Fault (FAM) located in the Betic Cordillera (Spain). In this study several intersegment areas were defined. Some structural and paleoseismic studies and geophysical surveys have been carried out on these zones., Research project reference code: CGL2013-47412-C2-1-P, Peer reviewed

The acquired data comprises 2D/3D and 3C components. The acquisition employed 647 seismic receivers, distributed in a 3D mesh around the target and along six 2D crooked lines sampling the study area. The source employed was a 32 t vibroseis truck, operating at c. 900 points in the pathways along the 2D profiles. Each vibration point was used three times, with frequency sweeps of 10-100 Hz., Fair and sustainable production of raw materials is one of the main challenges faced by our society. Through its RawMaterials Programme, the European Institute of Technology (EIT) encourages research and innovation solutions for mineral exploration to make them safer, sustainable and cost-effective. The SIT4ME project, funded by EIT, addresses these objectives by undertaking seismic mineral exploration methods in crystalline tectonic settings, at a reduced cost. The SIT4Me project will analyse the efficiency of passive seismic methods (i.e. ambient noise interferometry) for subsurface imaging, by comparing active- and passive-source datasets in mining areas. The files in this dataset correspond to the controlled-source acquisition., European Institute of Innovation & Technology, Grant number EIT 17024, SIT4ME project, Peer reviewed

The data acquisition contract was awarded to ENRESA and took place in November and December 2013. Seismic data was successfully collected in the Záncara river basin (Cuenca, Spain). The total amount of seismic reflection data collected was 9.7 km in 4 high-resolution seismic reflection profiles E-W oriented. Technical specifications of the profiles: Seismometer: 10 24-channel GEODE ultra-light seismic recordes, Receiver number: 240, Receiver interval: 2 m, Source: accelerated weightdrop 250 kg and 100 kg, Source interval: 6 m, Sample rate: 1 ms, Record time: 4 s. Contact person: Carbonell, R., rcarbo@ictja.csic.es, A high-resolution 2-D seismic reflection survey was acquired to obtain a seismic image of the geological structure of the Záncara river basin (eastern Spain). The study area consists of lutites and gypsum from a Neogene sedimentary sequence. The project also targeted the geometry of the geological structure and the mechanical properties of the underground materials. In addition, this study allowed for an improvement of the geophysical acquisition technics and protocols that provided with a better resolution seismic imaging. Thus, reducing costs and improving the effectiveness of the seismic acquisition., Convenio Colaboración CSIC-ENRESA. Código CSIC: 20133830, Peer reviewed

The data acquisition contract was awarded to ENRESA and took place in January 2014. Seismic data was successfully collected in the Záncara river basin (Cuenca, Spain). This is a high-resolution seismic tomography survey to obtain a full 3-D P-wave seismic velocity image of the studied area. A regular and dense grid of 676 shots and 1200 receivers was used to image a 500 m x 500 m area of the shallow surface. A 240-channel system and a seismic source, consisting of an accelerated weight drop, were used in the acquisition. Half a million travel-time picks were inverted to provide the 3-D seismic velocity distribution up to 120 m depth. The 3-D survey was acquired in five swaths, each one consisting on five receiver lines, resulting in a total of 3380 shot gathers. Technical specifications of the profiles: Receiver number: 240, Receiver interval: 2 m, Source accelerated weightdrop: 250 kg, Source interval: 6 m, Sample rate: 1 ms, Record time: 4 s., In this repository, in addition to the seismic 3DSurvey, a resistivity model (VICANAS_3D_Res_UTM30), a lithological model (VICANAS_3D_Vp_Res_Lito_UTM30), and a training set (VICANAS_Training_set) are available. In order to improve the geological interpretation of the seismic tomography, we integrated it with the resistivity model to build a 3D lithological model. To this aim, we created a new bi-parameter grid with Vp and Res values at each node. Then, we lithologically classified the nodes using supervised learning according to a training set extracted from the wells., A high-resolution seismic tomography survey was acquired to obtain a full 3-D P-wave seismic velocity image of the Záncara river basin (eastern Spain). The study area consists of lutites and gypsum from a Neogene sedimentary sequence. The project also targeted the geometry of the underground structure with emphasis on defining the lithological contacts but also the presence of cavities and faults or fractures. An extensive drilling campaign provided uniquely tight constraints on the lithology; these included core samples and wireline geophysical measurements. The analysis of the well log data enabled the accurate definition of the lithological boundaries and provided an estimate of the seismic velocity ranges associated with each lithology. The final joint interpreted image reveals a wedge-shaped structure consisting of four different lithological units. The study features the necessary key elements to test the travel time tomographic inversion approach for the high-resolution characterization of the shallow surface. In this methodological validation test, travel-time tomography demonstrated to be a powerful tool with a relatively high capacity for imaging in detail the lithological contrasts of evaporitic sequences located at very shallow depths, when integrated with additional geological and geophysical data., Convenio Colaboración CSIC-ENRESA.
