Elongate rutile (TiO2) in a ~3.5 x 2.5 cm block of eclogite, a high-pressure rock composed of garnet, pyroxene, rutile, and quartz. The sample is from the Montagne Noire structural dome, France. Imaging of a similar rock from another region of the Montagne Noire dome yielded a different fabric, documenting variation in strain under high-pressure conditions of the deep crust during the late stages of evolution of this mountain system.
In the All phases video different colors correspond to different phases: Quartz is dark blue, garnet is green, rutile is yellow, and red is matrix. In the videos for individual phases different colors correspond to unique grains.
