Resumo
In the present work, the mineralogy of the Chamorga outcrop (Tenerife, Canary Islands, Spain) has been studied by means of combining Raman-infrared spectroscopy (through laboratory instrumentation and the ExoMars Raman Laser spectrometer simulator (RLS)), X ray diffraction (XRD) and X ray fluorescence (XRF) (through portable systems). The research carried out, which includes a field-trip analysis and laboratory studies, is focused on the mineralogical characterization of terrestrial analogs. We have detected and analyzed iron-oxides, titanium-oxides, chromium-oxides, silica, phosphates, pyroxenes, plagioclases, K-feldspars, zeolites, clays, and organics (through carbonaceous material). The applied Raman methodology allowed us to carry out a full characterization of the samples’ mineralogy. Also, we have conducted a mineralogical semi-quantification (RIR) of samples by XRD that also includes the detection of elements such as Ca, Mn, Ti, and Fe obtained through XRF. The results obtained are: 1) the Raman characterization of the primary and secondary minerals; 2) the mineralogical comparison of the analog site with other nearby regions for constructing a database; 3) substantiate the importance of vibrational spectroscopy on planetary missions; 4) highlight the need to carry out this line on research for future testing of the prototypes in the field such as the ExoMars rover; and 5) to propose the Chamorga outcrop in combination with related outcrops of the Anaga Massif as a possible region of interest for a planetary database of terrestrial analogs and a possible place for astronaut simulated missions, given their mineralogy and geomorphology.
