This data set contains synchrotron diffraction images in TIF format. The images are of San Carlos Olivine minerals compressed and sheared in a newly introduced dynamic rotation diamond anvil cell. The purpose for collecting this data set is trying to induce olivine-spinel phase transformation at room temperature for the first time under severe plastic strain and investigate the strain-induced phase transformation mechanism of olivine. The strain-induced phase transformation of olivine could be the key to solving many enigmas of deep-focus earthquakes.
