Outline of Final Research Achievements

To get a better understanding of fault-weakening mechanism in silicic material, we have studied microstructure of the fault surface material in the samples derived from intermediate-velocity friction experiments on chert, and frictional properties of silicic sediments from the Cocos plate offshore the Osa Peninsula, Costa Rica. TEM observation reveals that the fault surfaces in chert after the experiments consist of several hundred-nm-thick amorphous silica layer. Wear rolls exist on the smooth fault surface. We find that rolls are also made of amorphous silica. Friction of the silicic sediments from the Costa Rica show velocity-weakening at velocities to 0.3 mm/s and neutral to velocity-strengthening behavior at velocities from 0.3 mm/s to 3 mm/s. At velocities higher than 30 mm/s, steady state friction values are as low as 0.1. These results imply the important influence of the generation and/or incorporation of amorphous silica on frictional behavior of silicic faults.
