Hydrothermal activity

Post by admin »

Hydrothermal activity involves the circulation of water in the crust driven by a heat source, such as volcanism or an impact event, and were the topic of my PhD dissertation. There is evidence of hydrothermal activity in Mars' past (1,2,3). Hydrothermal activity has the ability to concentrate relatively rare elements and produce mineral assemblages such as clays, sulfates, zeolite, hematite, magnetite, sodium silicates, carbonates, borates, phosphates, etc. All of these have been detected on Mars in significant quantities from orbit (using instruments such as CRISM and OMEGA), by Mars rovers, and/or found in martian meteorites. These minerals have potential uses as construction and manufacturing materials, adhesives, dyes, detergents, disinfectants, fertilizers, etc.
