Short summary
Rocks are brought to great depths and back to the Earth's surface by the tectonic processes that shape mountain ranges. Tiny mineral inclusions can record how deep rocks went. Quartz, a common mineral inclusion, was put in the laboratory at conditions that mimic those encountered at depths to about 100 km. A laser-based spectroscopy (Raman) was calibrated to read pressure from quartz inclusions in rocks and to unravel their deep travel.
