Granular titanite from the Roter Kamm crater in Namibia: Product of regional metamorphism, not meteorite impact

Accessory minerals with so-called granular texture have risen in importance as geochronological tools for U-Pb dating of meteorite impact events. Grain-scale recrystallization, typically triggered by a combination of high-strain deformation and post-impact heating, can create a polycrystalline micro...
