Seminar Detail
Life in igneous rocks on Earth and Mars
Presenter: Martin Fisk
November 29, 2005 02:30 PM Pacific
Microbes are found in and near microtunnels in a variety of igneous rocks on Earth. Although the microtunnels have not been produced in laboratory cultures, all indications are that microbes made the tunnels. The tunnels provide long-lasting markers of life on Earth and if microbes ever lived on Mars, they would have left similar evidence in the igneous rocks there.
