Ancient Earthquake Broke Garnets Deep in the Earth's Crust (1 of 6)

Caption

Focused ion beam image of small mineral inclusions that formed inside the fragmented garnet crystal due to fluid transport into pores in the garnet in the wake of the earthquake. The largest inclusions are about 20 micrometers long. This material relates to a paper that appeared in the Feb. 22 2017, issue of Science Advances, published by AAAS. The paper, by H. Austrheim at University of Oslo in Oslo, Norway, and colleagues was titled, "Fragmentation of wall rock garnets during deep crustal earthquakes."
