New Evidence Suggests Mars Has Been Cold and Dry

Denver - Oct. 31, 2000 - U.S. Geological Survey (USGS) scientists studying Mars have discovered minerals with profound implications for the past history of the planet. The mineral olivine, an iron-magnesium silicate that weathers easily by water, has been found in abundance on Mars. The presence of olivine implies that chemical weathering by water is low on the planet and that Mars has been cold and dry throughout its geologic history.
