Researchers Detect Hint of Oxygen 50 to 100 Million-Years-Earlier than First Believed
September 27, 2007
Two multinational teams of scientists, including researchers from Arizona State University, are reporting that traces of oxygen appeared in the earth's atmosphere 50 to 100 million-years-before the "Great Oxidation Event." Analyzing layers of sedimentary rock in a core sample from the Hamersley Basin in Western Australia, the researchers report finding evidence that a small but significant amount of oxygen--a whiff--was present in the oceans and possibly in the earth's atmosphere.
