Publicación Restringido Magnetic Induction-Based Susceptometer: Calibration Procedure for Complex Susceptibility Measurement and Extended Application in Natural Scenarios(Institute of Electrical and Electronics Engineers, 2023-01-27) Mesa, José Luis; Hernández Ros, C. A.; Díaz Michelena, Marina; Instituto Nacional de Técnica Aeroespacial (INTA); Ministerio de Ciencia e Innovación (MICINN); European Commission (EC); Agencia Estatal de Investigación (AEI)The fast and in situ measurement of the complex magnetic susceptibility stands a potential geological tool for enhanced characterization of rocks and comprehension of the geological context of the landing and exploration sites when used on board planetary rovers. The real part of susceptibility is related to the capability to acquire magnetization and the imaginary part, with resistivity and magnetic energy loss mechanism of rocks. Therefore, the determination of the rocks’ susceptibility provides key information as to the need for the presence of water in the formation of certain minerals, which can be used as one of the rocks selection criteria, in sample return missions. Previous work has been done in the conception of a novel portable instrument, based on magnetic induction, to measure the complex susceptibility of rocks in the context of planetary exploration. The next step is to create a comprehensive calibration procedure to extract magnetic properties information from the direct readings. This work describes a novel instrument calibration methodology. The calibration of the novel instrument comprises a comparative methodology with representative patterns for the real and the imaginary components of the susceptibility. Therefore, the work also includes calibration sample conception, manufacture, and characterization by different techniques.Publicación Restringido Synthesis and magnetic properties of single phase titanomagnetites(AIP Publishing, 2014-03-11) Schoenthal, W.; Liu, X.; Cox, T.; Mesa, José Luis; Maícas, N.; Díaz Michelena, Marina; Laughlin, David E.; McHenry, M. E.The focus of this paper is the study of cation distributions and resulting magnetizations in titanomagnetites (TMs), (1−x)Fe3O4−xFe2TiO4 solid solutions. TM remnant states are hypothesized to contribute to planetary magnetic field anomalies. This work correlates experimental data with proposed models for the TM pseudobinary. Improved synthesis procedures are reported for single phase Ulvöspinel (Fe2TiO4), and TM solid solutions were made using solid state synthesis techniques. X-ray diffraction and scanning electron microscopy show samples to be single phase solid solutions. M-H curves of TM75, 80, 85, 90, and 95 (TMX where X = at. % of ulvöspinel) were measured using a Physical Property Measurement System at 10 K, in fields of 0 to 8 T. The saturation magnetization was found to be close to that predicted by the Neel model for cation distribution in TMs. M-T curves of the remnant magnetization were measured from 10 K to 350 K. The remnant magnetization was acquired at 10 K by applying an 8 T field and then releasing the field. Experimental Neel temperatures are reported for samples in the Neel model ground state.Publicación Acceso Abierto The formation of a giant collapse caprock sinkhole on the Barda Negra plateau basalts (Argentina): Magnetic, mineralogical and morphostructural evidences(Elsevier BV, 2020-10-15) Díaz Michelena, Marina; Kilian, R.; Baeza, O.; Ríos, F.; Ángel Rivero, M.; Mesa, José Luis; González, Veracruz; Arlensiú Ordoñez, A.; Langlais, B.; Rocca, M. C. L.; Acevedo, R. D.; Agencia Estatal de Investigación (AEI); European Research Council (ERC)The 1.5-km-wide, 40-m-deep, crater-like structure in the 10 Ma old Barda Negra basaltic plateau in Central Argentina was discovered in the early 2000s. Based on remote sensing surveys and on its morphological characteristics, similar to those of the Barringer crater in Arizona, the structure is described to be originated by an impact. In this study we ran several field work campaigns and collected and analysed samples, in order to find more evidences to endorse or reject this hypothesis. We observe a circular depression not generally surrounded by raised rims, in contrast to craters produced either by a meteorite impact or phreatomagmatic eruption (maars). Mineralogical investigations of rocks and sediments do not show high pressure and temperature minerals, such as coesite or stishovite, or any remnants of an impactite or impact melt/glass. Likewise, no textural evidences for impact-related fracturing or stress are observed. A detailed geomorphological mapping indicates a successive crater development which invokes local stepwise subsidence. Magnetic mapping performed with the EU-funded NEWTON multisensor novel instrument shows a ~2000 nT field anomaly associated to the edges of the crater, and susceptibility measurements cast an important contrast between the basaltic rims and plateau, and the crater interior. Therefore, we propose a sinkhole origin for the crater, with a former collapse of the plateau basalts and a latter infill with sedimentary material. This hypothesis is supported by the fact that the 40 to 85 m thick and 14 to 15 Ma old carbonate-bearing Collón Curá Formation, underneath the 100 to 150 m thick basaltic plateau lava sheet, represents ideal rocks for dissolution and karst formation; remote sensing data show other nearby sinkholes (20 km westward), with extensions of 3 × 6 km and 100 m depth, which are emplaced within a cogenetic neighboring basaltic plateau with a similar underlying lithology; and the consistence of the magnetic model computed with this scheme and on measured rock remanence and susceptibilities of the structure and surroundings. These giant collapse sinkholes, up to 6 km in diameter, within caprocks of very thick plateau basalts, represent unique examples for planetary surface shaping processes which also occur on Mars and comets in areas with basalts or rigid caprocks.Publicación Acceso Abierto Single Point Gradiometer for Planetary Applications(Institute of Electrical and Electronics Engineers, 2015-03-09) Mesa, José Luis; Díaz Michelena, Marina; Ciudad, D.; Schoenthal, W.; McHenry, M. E.; Maicas, M.; Aroca, C.; Ministerio de Ciencia e Innovación (MICINN)We have designed and fabricated a microelectromechanical device, based on the alternating field gradient concept, to measure surface magnetic field gradient on planets. Its sensitivity is 4 10 -4 T/m, which is appropriate for magnetite outcrops and areas with rocks formed at different stages recording geomagnetic field reversals. We present the results obtained with three different prototypes.Publicación Acceso Abierto A novel induction-based device for the measurement of the complex magnetic susceptibility(Elsevier, 2017-08-13) Díaz Michelena, Marina; Mesa, José Luis; Pérez jiménez, M.; Maicas Ramos, M. C.; Cobos Arribas, P.; Hernández Ros, C. A.; Mesa, José Luis; European Research Council (ERC)A device named magnetic susceptometer for a complete determination of the magnetic complex susceptibility of materials and minerals has been conceived and manufactured as a complement for the in situ characterization of rocks during high resolution magnetic prospections. In this work a device and its capabilities for susceptibility measurements are described, the calibration performed with artificial samples, and the values of real and imaginary susceptibility of natural samples in a range comprising: χ = 10−4 to 10−7 [SI], representative of Earth and also Mars rocks.Publicación Acceso Abierto Magnetometric Surveys for the Non-Invasive Surface and Subsurface Interpretation of Volcanic Structures in Planetary Exploration, a Case Study of Several Volcanoes in the Iberian Peninsula(Multidisciplinary Digital Publishing Institute (MDPI), 2022-04-24) Díaz Michelena, Marina; Kilian, R.; Ángel Rivero, M.; Fernández Romero, S.; Ríos, F.; Mesa, José Luis; Oyarzún, A.; Instituto Nacional de Técnica Aeroespacial (INTA); Agencia Estatal de Investigación (AEI); European Commission (EC)Volcanoes are typical features of the solar system that offer a window into the interior of planets. Thus, their study can improve the understanding of the interiors and evolution of planets. On Earth, volcanoes are monitored by multiple sensors during their dormant and active phases. Presently, this is not feasible for other planets’ volcanoes. However, robotic vehicles and the recent technological demonstration of Ingenuity on Mars open up the possibility of using the powerful and non-destructive geophysical tool of magnetic surveys at different heights, for the investigation of surfaces and subsurfaces. We propose a methodology with a view to extract information from planetary volcanoes in the short and medium term, which comprises an analysis of the morphology using images, magnetic field surveys at different heights, in situ measurements of magnetic susceptibility, and simplified models for the interpretation of geological structures. This methodology is applied successfully to the study of different examples of the main volcanic zones of the Iberian Peninsula, representative of the Martian intraplate volcanism and similar to Venus domes, as a preparatory action prior to the exploration of the rocky planets’ surfaces.Publicación Restringido Design of a Portable Susceptometer With No Electromagnets(Institute of Electrical and Electronics Engineers (IEEE), 2023-12-04) Rivelles García, Alejandro; Sanz Lluch, María del Mar; Maicas, Marco; Mesa, José Luis; Díaz Michelena, Marina; Aroca, Claudio; Ministerio de Ciencia e Innovación (MICINN); European Research Council (ERC)Magnetic materials characterization usually requires heavy equipment based on electromagnets, which limits their use to the laboratory. The volume of the typical samples is small in order to keep a good uniformity of the applied magnetic field in the sample. This kind of equipment is not appropriate for geological measurements in the field, where portable systems are required and samples have typically a higher volume. Here, we study the limits and applicability of a portable susceptometer device based on strong magnets potentially applicable in geological prospections. A new prototype has been built and tested. The device makes use of Nd–Fe–B magnets and an iron magnetic circuit (MC) to apply the magnetic field to the sample. A quasi-spherical geometry of the MC provides good uniformity of the magnetic field while keeping a moderate measuring volume. The equipment is powered by a 12-V battery and a mechanical design allows the control of the magnetic flux density in the range of approximately 30–130 mT.
