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.

The Ciexaus yamana ceremony that toke place in 1920 in Estancia Remolino (northern Coast of the Beagle Channel, Argentina) was described by the ethnographer Martin Gusinde. The site was excavated archaeologically during 2001 to obtain an image of an actual and historially documented ceremonial archaeological layer. The final aim was to evaluate the significant variables that would potentially allow to identify an ceremonial place. The conclusion was that a ceremonial place can be identify not just by the kind of items but by the treatment given to those materials and to the place. These important ceremonies did not happen at an especifical place. The effemeral use of the places difficults to separate and to identify the occupied surface. The excavation recovered some features of the ceremonial hut, materials of previous occupations as well as materials from later moments. All those materials were recovered by square meters and by the strata identified. The database is contained in an Excel file. This file has five sheets. The first one contains the description of the square and layer where each item was found as well as a formalised analitical desciption. The second sheet contains the keys for the descriptions. The third contains tables of distribution of the different types of materials by layers and squares. The fourth a dinamic table that can be used for obtained a frequency distribution graph by squares. The fifth contains the tables used to graph the frequencies of materials types by layers., The DataBase contains an analitical description of the materials found. Basically fragments of glass containers, bones and and metal items, as well as some stone tools in the lowest level corresponding to some pre-european contact moment. The most significant material has been fotografied and included in the collection SORIYAM., Agencias financiadoras: CSIC, CONICET, Ministerio de Educación y Ciencia (España) y Universidad de Barcelona (España)., No

The study area covers an area of 36 km2 and included approximately 5000 mixed (Vibroseis and explosives) source points recorded with a 25 m inline source and receiver spacing., The Basque–Cantabrian Basin of the northern Iberia Peninsula constitutes a unique example of a major deformation system, featuring a dome structure developed by extensional tectonics followed by compressional reactivation. The occurrence of natural resources in the area and the possibility of establishing a geological storage site for carbon dioxide motivated the acquisition of a 3-D seismic reflection survey in 2010, centered on the Jurassic Hontomín dome. The objectives of this survey were to obtain a geological model of the overall structure and to establish a baseline model for a possible geological CO2 storage site., Spanish Ministry of Industry, Tourism and Trade through the CIUDEN and ICTJA agreement.--European Union through the Technology Demonstration Plant of Compostilla.--Spanish Ministry of Education Science.--Generalitat de Catalunya.--, Peer reviewed
