Witwatersrand Basin showing location of mines sample during LExEn deep microbiology project.

The South African Deep Microbiology Project - characterizing the microbiology and geochemistry of continental crust down to 5 km! (sponsored by NSF/NASA)

HighLakeSatelliteImage

Satellite image of High Lake site in Arctic Canada selected as a Mars analog site where 200 meters of permafrost was collected this summer. Drill site and horizontal projection of 530 meter borehole penetrating the permafrost is show by red dot and line. Orange regions are oxidized sulfide deposits, natural acid drainage sites for future investigations.
