What sedimentary rocks can tell us about the evolution of Earth’s atmosphere
Home
Rocks have a lot to tell us about the history of our planet. Geologists study rocks to identify the clues they hold and decipher the answers they reveal.
Dr Robert Rainbird, a sedimentologist at the Geological Survey of Canada, is examining ancient sedimentary rocks in the Temagami region of northeastern Ontario to look for evidence of the Great Oxygenation Event – the time at which Earth’s atmosphere first became oxygen-rich, setting the stage for the emergence of early life.
This brochure introduces Rob's work, offers an insight into careers in sedimentology, contains an interview with Rob and includes an activity sheet that challenges students to describe a sedimentary rock based on the conditions under which it formed.
