[作者:Chen, CW; Rondenay, S; Evans, RL; Snyder, DB,期刊:Science, 页码:1089-1091 , 文章类型: Article,,卷期:2009年326-5956]
- When plate tectonics started on Earth has been uncertain, and its role in the assembly of early continents is not well understood. By synthesizing coincident seismic and electrical profiles, we show that subduction proce...
- Atmospheric Sulfur in Archean Komatiite-Hosted Nickel Deposits
[作者:Bekker, A; Barley, ME; Fiorentini, ML; Rouxel, OJ; Rumble, D; Beresford, SW,期刊:Science, 页码:1086-1089 , 文章类型: Article,,卷期:2009年326-5956]
- Some of Earth's largest iron-nickel (Fe-Ni) sulfide ore deposits formed during the Archean and early Proterozoic. Establishing the origin of the metals and sulfur in these deposits is critical for understanding their gen...
