Abstract

Field studies and analytical scanning electron microscopy indicate that a hydrothermal system was created by the interaction of groundwater with hot, impact-generated rocks at the 24 km diameter, 23 million year-old Haughton impact structure on Devon Island, Nunavut, Arctic Canada (Osinski et al., 2001). The nature, distribution, duration, and preserved record of this hydrothermal activity at Haughton is of interest not only for gaining a better understanding of the impact cratering process on planets with H2O-rich surface materials, but also for helping assess the possible biological opportunities created by impacts. Here, I review recent hydrothermal findings at Haughton and discuss possible implications in the specific case of Mars.
