“…For such a scenario one would expect also the formation of a set of associated secondary minerals, such as carbonates and sulfates. These are commonly found in terrestrial playa evaporates [e.g., Eugster and Hardie , 1978; Baldridge et al , 2004; Sgavetti et al , 2009]. While carbonates have not been detected by OMEGA so far [ Jouglet et al , 2007], they have been remotely observed as excavated materials only with CRISM higher spatial resolution data [ Ehlmann et al , 2008; Michalski et al , 2012].…”

1] Several hundred occurrences of chloride-bearing salt deposits have been proposed in terrains within the southern highlands of Mars on the basis of Thermal Emission Imaging System and Thermal Emission Spectrometer infrared observations. The spectral identification of chloride salts by remote sensing is challenging because they are transparent over much of the thermal infrared portion of the spectrum. Further ambiguity arises from the diverse geologic settings in which the putative chloride-bearing materials are found. In order to better constrain the composition of these unique compositional units, we perform a global survey of these materials in the Near-Infrared (NIR) domain with the Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité (OMEGA) imaging spectrometer. The spectral signatures of the deposits are consistent withalthough not specific ofchlorides. We do not observe olivine to be associated with the deposits, which confirms that sulfides are an unlikely alternative candidate. Our systematic search reveals the global lack of association with hydrated minerals (phyllosilicates, sulfates, hydrated silica) except for a few deposits (noteworthy in northwestern Terra Sirenum) where a small fraction of chloride material overlaps Fe/Mg-rich clay-bearing terrains. Even in these locations, the morphology and crosscutting relationships of the deposits suggest two separate episodes of mineralization, first phyllosilicates then chlorides, followed by subsequent formation of sulfates. Our study shows that local groundwater upwelling seems to be the most frequent source for the water involved in the formation of chloride, rather than surface runoff.

“…The few previous studies have indicated supergenic sulfate in Solfatara and Pisciarelli (Parascandola, 1947;Valentino et al, 1999) and similarities between the hydrothermal phases at Solfatara and those sampled on Mars (Sgavetti et al, 2008). The environment is colonized by algae (Cennamo et al, 2002) and bacteria (Glamoclija et al, 2004), as a function of water presence, temperature, and pH.…”

“…In particular, Site 1 is situated above the Solfatara cryptodome whereas Site 2 is seated in an area of formation and circulation of condensate flow originating from the intense degassing characterizing the sector . The mineralogy of Solfatara is characterized by native sulfur and a sulphate paragenesis, alunite, and alunogen with other sulphates derived from supergenic oxidation of volcanic H 2 S …”

To study the dynamics of active volcanic environments, minerals involved in fresh lava flows are a nice probe and Raman spectroscopy is an excellent tool for their characterization. Because of the highly hostile environment linked to volcanic activity, studying lava cooling and weathering needs remote setups and specific procedures dedicated to medium‐high temperature targets. In this paper, we present the remote Raman characterization of sulfur produce by the fumarolic activity at Solfatara crater (Phlegraean Fields, Italy). Two medium temperature sites (280–380 K) were probed with two different Raman setups. For both, β‐sulfur is the prominent type in the entire temperature range and the absolute local temperature of the sulfur was remotely estimated by mean of a Stokes/anti‐Stokes procedure with ±10 K uncertainty. These results represent a good starting point for the development of new setups and protocols aimed to an increase of both measurement distance and temperature range.
