V51B:
Geochemistry of Sediments and Sediment Recycling and Implications for Crust and Mantle Evolution over Earth History II Posters


Session ID#: 10934

Session Description:
Sedimentary rocks record information on diverse topics such as environmental conditions from the distant past, the average composition of the continents, and the redox state of the oceans and atmosphere.  Although much of the Earth’s sedimentary record has been removed from our view by subduction processes, a long term consequence may be that the mantle “sees” and is influenced by Earth surface conditions.  We seek a broad range of contributions that deal with the record of continental evolution and the rise of oxygen, seen both in the sedimentary record and also potentially in igneous systems as a result of sediment recycling over Earth history.
