[MSA-talk] IMA (Johannesburg, South Africa) session on carbon-mineral interactions

[Glenn Waychunas]

Dear Folks:

A reminder that abstracts are due for the IMA general meeting in Johannesburg South Africa (September 1-5, 2014) on Monday March 10.  Our session deals with carbon-mineral interactions and should be of interest to many:

Environmental mineralogy and the carbon cycle

 

Convenors: Dr. Ben Gilbert, LBNL; Dr. Glenn Waychunas, LBNL

 

Description:

Interactions between minerals and organic carbon in the environment can exert a major effect on biogeochemical processes including many aspects of the carbon cycle. For example, there is gathering evidence that such interactions stabilize organic materials (OM) in deep soil horizons, reduce the rate of OM oxidation, and affect OM aggregation behavior and dispersal. Knowledge from the molecular-scale to colloid scale and larger is likely necessary to understand these observations, and thereby potentially enable improvements in environmental carbon stabilization. We seek contributions that address all aspects of organic-mineral interactions, including mineral precipitation and growth, molecular adsorption to mineral interfaces, and abiotic and biological carbon degradation. We welcome field studies that reveal the mechanisms and extent of mineral effects on carbon cycling such as the coupled evolution of mineralogical and OM contents of soils, or mineral colloid controls on OM transport. We further encourage laboratory and computational studies on fundamental aspects of mineralogical controls on organic processes.
