PP14B:
Diagenesis and Its Effects on Geochemical Records II

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17416

Session Description:
The purpose of this session is to bring together geochemists from multiple disciplines who study the myriad chemical processes which occur after the emplacement of sediment (diagenesis). One focus of discussion will be on the application of geochemical tools towards studying the mechanisms and rates of these reactions. Additionally, submissions which assess the ways in which these chemical reactions can affect geochemical records, as well as potential approaches towards correcting for these effects, are encouraged.
