Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

Photoluminescence and Cathodoluminescence of the Solid Cometary Substance
Open Astronomy, 2019 We have proposed that solar ultraviolet and corpuscular radiations may excite photoluminescence and cathodoluminescence of the solid cometary substance including mineral halos of comets.
