MR41E:
Experimental Measurements and Theoretical Constraints on Transport Properties of Geomaterials I

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#: 15955

Session Description:
Basic understanding of the dynamic evolution of our planet is linked to knowledge of the physical properties of the relevant solid materials. This session is dedicated to studies of the deformation, diffusion, electrical conductivity, and other kinetic properties of geomaterials. These transport processes are linked to each other by the thermodynamic properties and point defect chemistry of the minerals, providing an integrated understanding and cross-calibration of the measurements and calculations. This session emphasizes a broad perspective with insights from both experimental and computational studies as well as theoretical connections between the different transport properties.
