Within active plate boundaries, the rock cycle involves lithospheric deformation to exhume rocks to the surface. We show that trapped inclusions in garnet sand from the actively exhuming high- and ultrahigh-pressure metamorphic terrane of eastern Papua New Guinea preserve a record of crustal subduction and rapid exhumation linking upper mantle and surface processes operative on short geologic timescales (<10 My). Detrital garnet geochemistry and their inclusion suites from both modern sediments and stratigraphic sections can be used to reveal rock recycling processes throughout Earth’s history. %Z https://katalog.ub.tu-freiberg.de/Record/ai-49-aHR0cDovL2R4LmRvaS5vcmcvMTAuMTA3My9wbmFzLjIwMTcyMzExMTg %U https://katalog.ub.tu-freiberg.de/Record/ai-49-aHR0cDovL2R4LmRvaS5vcmcvMTAuMTA3My9wbmFzLjIwMTcyMzExMTg
