#hydrothermal

Life on Mars has always been a draw, so where should we look? 25 years ago a popular idea was hydrothermal sites. As the name suggests, they combine heat and water, so obvious candidates would be volcanic areas with evidence of water. James Dohm (then at U. Arizona) mapped two sets of them, shown on this map. 1998 sites were in Thaumasia where many channels indicate water. Sites in 2000 were more widely distributed around Tharsis. None of these have been visited yet.

"the crater it left behind in the #GulfOfMexico was a literal hotbed for life, enriching the overlying #ocean for at least 700,000 years... a #hydrothermal system created by the #asteroid impact may have helped marine life flourish at the impact site by generating and circulating nutrients in the crater environment."

photo - View to the southwest of the eastern front of the Gallatin Range from Gardners Hole. The East Gallatin-Reese Creek fault system runs along the base of the range at the prominent break-in-slope in the trees.

maps - Lidar hillshade maps of fault scarps that offset Pinedale glacial till along the East Gallatin-Reese Creek fault system (EGRCFS) near Fawn Creek (A) and Panther Creek (B). Fault scarps are visible as darker lineaments in the hillshade and are marked by the black arrows. Red rectangles on inset maps show location along the EGRCFS.

map - Shaded relief location map for the East Gallatin-Reese Creek fault system (EGRCFS) in northwest Yellowstone National Park (YNP). The location of the EGRCFS is shown as mapped in the U.S. Geological Survey Quaternary Fault and Fold Database, subdivided into the southern East Gallatin section (blue dashed line) and the northern Reese Creek section (black dashed line). Red rectangle on inset map shows location within Yellowstone National Park.

Discovery of the first hydrothermal field along the 500-km-long Knipovich Ridge offshore #Svalbard (the Jøtul field) https://www.nature.com/articles/s41598-024-60802-3

The Jøtul Field’s intense #methane concentrations suggest an intense interaction between magma and oceanic sediments.

photo - underwater - Thriving at a depth of 3,000 meters near the Jotul Vent Field s hydrothermal vents, this Hairy decapod shrimp hosts bacteria colonies forming hairs that convert toxic hydrogen sulfide into energy, mirroring a process similar to photosynthesis.

maps - (A) Map of the Norwegian-Greenland Sea (GEBCO data) with locations of active seafloor spreading centers and the study area. (B) Detailed map of the study area (ship-based multibeam data acquired during cruise MSM109) including the Brøgger Axial Volcanic Ridge (AVR) and the newly discovered hydrothermal active area called Jøtul hydrothermal field. (C) AUV-based bathymetry of the Jøtul hydrothermal field (data acquired during cruise MSM109 and provided by the Norwegian Offshore Directorate). Track lines of ROV dives are shown and track portions, where hydrothermal activity was visually observed, are marked in yellow. Four sites were sampled for fluids during MSM109 and are indicated by circles.

thin section photos - Thin section images of precipitates from Jøtul hydrothermal field taken under reflected light. (A) Thin section part of a copper-rich domain typical for the black smoker chimney (GeoB25031-2). Chalcopyrite and ISS are tightly intergrown and co-occur with cubanite and sphalerite. Some of the FeCu-sulfide grains are covered with chalcocite (lower left corner). Anhydrite occurs in veins and as void fill. (B) Typical paragenesis of blade-like, pseudohexagonal pyrrhotite crystals with cubanite and Fe-rich sphalerite in a thin section sample of the chimney structure at Yggdrasil vent site (GeoB25034-8), location shown in Fig. 1C. Small grains of galena appear to have formed coevally with sphalerite.

photos - (A) Low-temperature vent sites associated with magmatic host rocks. Hydrothermal activity between volcanic blocks with chilled columnar joints is documented by white precipitates of mostly barite, white bacterial filaments and siboglinid tube worms. Small limpets are attached to the white surface in the front and below the rock. (B) Sediment-dusted pillow lava flow with indications of hydrothermal venting from in between the lava tubes. (C) Seafloor outcrop of mineral precipitates dominated by dolomite, partly associated with siboglinid tube worms covered with white microbial mats. (D) Sampling of hot (316 °C) fluids at the black smoker through the intake nozzle of the KIPS sampling device. The sulfide chimney, composed of chalcopyrite, sphalerite, pyrrhotite and anhydrite did not grow vertically, but leans over to the north. This can be explained by bottom-water currents deflecting the outflowing fluid from a vertical to a northerly direction. (E) Barite and amorphous silica-rich chimney at Nidhogg venting edifice, densely populated by amphipods. (F) Top-most region of Yggdrasil vent site showing multi-flanged precipitation structures and shimmering water.

Perseverance Rover to Begin Long Climb Up Martian Crater Rim

Priority regions to study at the top of the crater are nicknamed “Witch Hazel Hill” and “Pico Turquino”, which contains ancient fractures that may have been caused by past hydrothermal activity.
