MR32A:
Physical Properties of Earth Materials (PPEM): Rock Deformation over Various Time and Spatial Scales 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#: 16432

Session Description:
This session is to showcase results of geoscientists and materials scientists who use experiments, theory and observation to study the properties of Earth’s materials. Deformation processes occur at various time scales, from seismogeneic fault slip to mantle convection. The nature of macroscopic properties and the forms of constitutive laws that operate at the plate scale depend upon physical and chemical processes that operate at scales down to atomic dimensions. The PPEM session welcome studies that discuss the nature and controls on rock strength, fracture, friction and ductile flow during both engineered and natural tectonic loading and at various time and spatial scales.
