Deformed monazite yields high-temperature tectonic ages.

The article discusses research by T. M. Erickson on how deformed monazite yields high-temperature tectonic ages. Topics covered include how Erickson considers crystal plastic processes of monazite as the only deformation mechanisms that completely reset the ages of U-Th-Pb and how microstructures diagnostic for crystal plastic creep of monazite are rare and restricted to fluid-deficient rocks.
